When Help Isn't Coming
EMS response time in rural areas averages 14 minutes — but that assumes the road is passable, the dispatcher can be reached, and the system isn't overwhelmed. During a grid-down event, a severe storm, or a regional emergency, help may be hours away or unavailable entirely. This guide synthesizes the Medical foundation's Tier 1 procedures into a single field reference: what to do, in what order, when you are the hospital.
Educational use only
This guide is for emergency preparedness scenarios when professional medical care is unavailable. It is not a substitute for professional medical advice or training. Seek professional care whenever possible. Use this information at your own risk.
Source foundations covered in this guide: Bleeding control · Wound care · Fractures and splinting · Wound infection recognition and treatment · Allergic reactions and anaphylaxis · Cold chain during power outages · Elder care and caregiver preparedness · Pandemic preparedness · Field hygiene · Heatstroke · Hypothermia · Dehydration · Post-disaster recovery
Field note
The procedures below assume you have the supplies, the training, and the household routine to use them. The Preparedness Self-Assessment is a 5-minute, 12-Foundation scorecard that exposes which gaps would bite you first in an extended event. Run it before you need this guide.
Any-1 tiebreaker (Medical / Water / Energy first wave): When the assessment surfaces multiple weak Foundations, close them in this order — Medical → Water → Energy first wave; Food / Shelter / Security second; the remaining six third. The rationale is mortality window: medical gaps kill in minutes (anaphylaxis, hemorrhage), water gaps kill in 3 days, energy gaps amplify medical (cold-chain meds, oxygen, CPAP) and food (refrigeration) failures within hours. This is also the order in which an unrehearsed household will discover, mid-event, what it doesn't have.
For households with chronic-condition members, infants, elderly, or other elevated medical exposure, read Medical-dependent household: routing and first-wave plan before relying on the field-medicine sections below — it routes you to the chronic-conditions, elder-care, infant-care, and cold-chain pages that this guide assumes you've already absorbed.
Triage first: sort before you treat
When multiple injured people are present, resist the impulse to treat the first person you reach. Use a 60-second scan to sort by urgency before committing to any one patient.
Immediate (treat now): Arterial bleeding, severe airway compromise, anaphylaxis with cardiovascular collapse, unconscious with pulse.
Delayed (treat next): Controlled bleeding, fractures without vascular compromise, moderate allergic reaction, conscious and stable.
Minimal (treat last): Minor wounds and abrasions, superficial burns, walking injured.
Expectant: Injuries incompatible with survival given available resources — absent pulse without airway obstruction, severe traumatic brain injury with fixed dilated pupils.
For every patient, use the Massive hemorrhage, Airway, Respiration, Circulation, Hypothermia (MARCH) sequence to prioritize your interventions: Massive hemorrhage → Airway → Respiration → Circulation → Hypothermia/Head injury. This order differs from the traditional "airway first" approach because hemorrhage kills faster than airway obstruction in most trauma scenarios.
Bleeding control
Uncontrolled hemorrhage is the leading cause of preventable traumatic death. A severed femoral artery empties in under three minutes. The interventions below are the only thing that stand between a bleeding patient and that outcome.
Classify the bleed
- Arterial: Bright red, pulsing in rhythm with the heartbeat. Tourniquet is the correct first response for limb arterial bleeding — not direct pressure alone.
- Venous: Dark red, steady flow. Responds to sustained direct pressure.
- Internal: No visible bleeding, but signs of shock — pale, cold, rapid weak pulse, confusion, falling blood pressure. Cannot be managed in the field. Recognition and rapid evacuation are the only interventions.
Direct pressure technique
- Expose the wound — cut or tear clothing away. You cannot control bleeding through fabric.
- Fold two or three gauze pads into a firm pad. If gauze is unavailable, use the cleanest cloth available.
- Apply firm, continuous pressure using the heel of both hands. Press with your full body weight for a thigh wound; firm pressure for a head wound.
- Maintain uninterrupted pressure for 10 full minutes without lifting to check. Every lift breaks the forming clot and restarts the clock.
- At 10 minutes, gently lift. If controlled, add a second dry pad over the first — do not remove the original — and secure with a wrap.
- If not controlled after 10 minutes on an extremity, escalate to tourniquet.
Never lift early
The most common bleeding control failure is checking the wound before 10 minutes have passed. Set a timer. Do not lift.
Wound packing
Use for deep wounds, junctional wounds (groin, armpit, neck/shoulder junction), and any wound where surface pressure is insufficient.
- Identify the deepest visible point of the wound cavity.
- Press hemostatic gauze (Combat Gauze, QuikClot) or plain gauze firmly into the deepest point with your finger.
- Pack tightly from the base upward until the cavity is filled and gauze is level with the skin surface.
- Apply hard pressure with both hands for 3 minutes with hemostatic gauze or 5 minutes with plain gauze.
- Do not remove the packing. Cover with a pressure dressing and maintain pressure during transport.
Tourniquet application
Apply immediately — before direct pressure — for arterial limb bleeding, amputation with hemorrhage, or blast trauma to a limb.
- Expose the limb — apply to bare skin only.
- Route the tourniquet around the limb 2–3 inches (5–7.5 cm) above the wound.
- Thread and pull the strap until all slack is removed.
- Twist the windlass until bleeding stops completely — not slows, but stops. This typically requires 3–5 full rotations and causes significant pain. If the patient tells you it hurts, continue.
- Lock the windlass rod into the retention clip.
- Write the time of application directly on the patient's forehead with a permanent marker: "TQ 14:32." This is not optional — it determines hospital treatment decisions.
- Do not cover the tourniquet. Do not loosen it in the field once applied.
Under-tightening creates venous congestion
A tourniquet that reduces but does not stop blood flow creates blood pooling below the tourniquet while arterial flow continues — worse than no tourniquet at all. If oozing continues after application, tighten further or apply a second tourniquet immediately above the first.
Shock prevention
After hemorrhage is controlled, prevent or treat shock:
- Lay the patient flat.
- Elevate legs 8–12 inches (20–30 cm) unless head, neck, chest, or abdominal injury is suspected.
- Cover with any available insulating material — hypothermia impairs clotting. A cold, shocked patient bleeds worse.
- Do not give fluids by mouth to unconscious or severely injured patients.
- Monitor mental status every 5 minutes — deteriorating consciousness indicates progressive shock.
For the full hemorrhage management protocol, including tourniquet time limits and junctional wound techniques, see bleeding control.
Wound care
Infection kills more people from wounds than the original injury. The first hour of wound care determines whether a wound heals or progresses to systemic sepsis.
Do not close these wounds
Regardless of appearance, never close: - Puncture wounds (narrow track traps bacteria; irrigation cannot reach the base) - Animal or human bites (oral bacteria cause aggressive deep tissue infection) - Any wound more than 8–12 hours old - Wounds with visible infection signs — pus, spreading redness, fever - Heavily contaminated wounds you cannot be certain are fully clean
Irrigation — the most important intervention
Research from the American College of Surgeons defines effective irrigation at 35–70 psi. This removes bacteria without driving contaminants deeper.
Equipment: A 35–60 mL syringe with an 18–19 gauge angiocatheter tip produces approximately 25–40 psi when the plunger is pushed firmly with both hands. This is your standard setup.
Saline recipe: Dissolve 2 level teaspoons (9 g) of non-iodized salt per 1 quart (1 liter) of boiled and cooled water to produce approximately 0.9% saline. Do not use hydrogen peroxide — it damages healing tissue.
Procedure: 1. Hold the syringe tip 1–2 inches (2.5–5 cm) from the wound surface — not pressed against it. 2. Push the plunger firmly and continuously into the deepest visible part of the wound. 3. Use at least 200–500 mL per irrigation session — more for infected wounds or heavy contamination. 4. Continue until the effluent runs clear. 5. For contaminated wounds, scrub the wound bed with a gauze pad after irrigation to dislodge embedded particles.
Field note
No syringe? A clean plastic bag with a pinhole or a water bottle with a small-hole cap can approximate low-pressure irrigation. Volume matters more than perfect pressure when equipment is limited.
Wound closure (strips)
For clean, low-tension lacerations under 1 inch (2.5 cm) that are less than 6–8 hours old and show no contamination:
- Dry wound edges completely — strips do not adhere to wet skin.
- Hold wound edges together with your fingers.
- Apply the first strip perpendicular to the wound, anchoring 1/2 inch (1.2 cm) from the edge on each side.
- Apply strips every 1/4 inch (6 mm) along the wound.
- Add a second layer parallel to the wound on each side, connecting the strip ends. This distributes tension and prevents peeling.
Dressing — the three-layer system
- Contact layer: Petroleum-impregnated gauze or non-stick pad directly on the wound bed. Never plain dry gauze — it adheres to healing tissue and tears it on removal.
- Absorbent layer: Standard gauze pads (4×4 inch / 10×10 cm).
- Securing wrap: Conforming bandage roll — snug, not tight. You should be able to slide one finger under the wrap. Check capillary refill: press the nail bed and release; color should return in under 2 seconds.
Change the dressing daily from 24–72 hours, or immediately if soaked, displaced, or contaminated.
For the full wound assessment grid, closure options, and dressing change schedule, see wound care.
Fractures and splinting
A fracture does not kill on its own. Vascular compromise, internal bleeding, and compartment syndrome do. Field splinting stops the injury from progressing and makes transport possible.
Identify a likely fracture
In the absence of imaging, look for: - Point tenderness: Firm, localized pain at one specific spot on the bone - Deformity: Angulation, shortening, or rotation compared to the other side - Crepitus: A grating sensation when the limb is gently handled - Inability to bear weight or use the limb
When in doubt, splint. You will not harm a sprain by splinting it; you will harm a fracture by leaving it unsplinted.
CSM check — before and after every splint
Perform a Circulation / Sensation / Movement check before splinting and immediately after.
- Circulation: Find the pulse distal to the injury (radial at the wrist for arm injuries; dorsalis pedis on the top of the foot for leg injuries). Check capillary refill — under 2 seconds is normal.
- Sensation: Touch the fingers or toes lightly and ask the patient to report feeling. Numbness or asymmetry is a significant finding.
- Movement: Ask the patient to wiggle their fingers or toes — not to move the injured limb.
Deteriorating CSM after splinting (loss of pulse, new numbness, loss of toe/finger movement) means the splint is too tight. Loosen immediately.
Splinting principles
- Immobilize the joint above and below the fracture.
- Pad all bony prominences before rigid material contacts the limb.
- Splint in the position of function: wrist slightly extended, ankle at 90 degrees, knee in slight flexion.
- Wrap snugly enough to hold position, loose enough for swelling.
- Recheck CSM every 30 minutes during transport.
Compartment syndrome — act on early signs
Compartment syndrome is a time-critical surgical emergency. The early signs are the ones that save the limb; the late signs mean damage is already irreversible.
Early signs (act now): - Pain out of proportion to the injury — severe, disproportionate - Pain on passive stretch: For lower leg: extend the toes backward toward the shin while holding the ankle; sharp calf pain is a positive finding. For forearm: extend the fingers backward; sharp forearm pain is a positive finding. - Tense, "woody" compartment: the skin over the affected area feels drum-like
Late signs (damage occurring): - Paresthesia (numbness or tingling) - Pallor distal to the injury - Paralysis — inability to move the extremity - Pulselessness — loss of distal pulse
The window closes fast
Paralysis and pulselessness indicate nerve and muscle death that fasciotomy may not fully reverse. Act when you feel pain on passive stretch and a tense compartment — loosen all wrappings immediately. If symptoms don't resolve within 30 minutes, this patient needs surgical fasciotomy and urgent evacuation.
For splinting by fracture location (forearm, ankle, femur, spine) and traction splint contraindications, see fractures and splinting.
Wound infection recognition
Infection begins 24–48 hours before any visible sign appears. Daily inspection catches it early; missing a day can mean the difference between oral antibiotics and a systemic emergency.
STONES daily assessment
Use this mnemonic for every wound, every day:
- S — Swelling: Increasing or decreasing since yesterday?
- T — Temperature: Hotter than the mirror-image location on the opposite limb?
- O — Odor: Foul smell = colonization; sweet/fruity odor with dark tissue = possible anaerobic infection
- N — New symptoms: Fever, chills, confusion, rapid heart rate?
- E — Exudate: Clear/pink = normal. Cloudy yellow = suspicious. Green/brown/bloody-opaque = infection.
- S — Size of redness: Use a permanent marker to outline the redness boundary, record date and time. Redness outside the line at the next check = spreading cellulitis requiring antibiotics.
Lymphangitis — red streaks mean emergency
A thin red line tracking from a wound toward the body core (arm → armpit; leg → groin) is lymphangitis — bacteria moving through lymphatic vessels toward the bloodstream. This is no longer a local wound problem.
When you see red streaks: 1. Start antibiotics immediately 2. Mark both ends of the streak with a marker, record date and time 3. Immobilize and elevate the affected limb 4. Monitor every 2–3 hours 5. Accelerate any evacuation plan — this patient may progress to bacteremia within hours
Red streaks are an emergency
Lymphangitis combined with fever above 102°F (38.9°C) and altered mental status is probable sepsis. No field intervention is adequate as definitive treatment. Begin evacuation immediately.
Sepsis recognition: qSOFA
When a wound infection goes systemic, use qSOFA to screen for sepsis without lab work. Score one point for each criterion:
| Criterion | How to assess |
|---|---|
| Altered mental status | Confused, disoriented, drowsy, unusual behavior |
| Respiratory rate ≥22 breaths/minute | Count breaths for 30 seconds, multiply by 2 |
| Systolic blood pressure ≤100 mm Hg | Check BP, or assess: rapid weak pulse, refill over 2 seconds, pale/mottled skin |
qSOFA score of 2 or 3 = probable sepsis. This is an evacuation emergency. Begin antibiotics immediately and move the patient toward emergency care. Every hour matters.
For the infection progression timeline, STONES framework, abscess drainage procedure, antibiotic selection by infection type, and lymphangitis tracking protocol, see wound infection recognition and treatment.
Allergic reactions and anaphylaxis
Anaphylaxis kills within minutes. The obstacle is almost never the drug — it is hesitation. Providers wait for textbook symptoms while the patient deteriorates. Epinephrine is the only first-line treatment, and nothing replaces it.
Grade the reaction
Mild — skin only: Hives, localized swelling, itching at one site. Not immediately life-threatening. Give antihistamine. Observe closely — mild reactions can escalate.
Moderate — skin plus one systemic sign: Add nausea, dizziness, mild wheezing, throat tightness, or diaphoresis. Prepare epinephrine for immediate use. Administer if symptoms are escalating rather than stabilizing.
Anaphylaxis: Two or more organ systems involved after allergen exposure — skin plus breathing difficulty, skin plus vomiting, breathing plus cardiovascular signs. Treat immediately. Also treat immediately for any cardiovascular or respiratory compromise alone after allergen exposure — up to 20% of anaphylaxis cases present with no skin signs.
No hives does not mean no anaphylaxis
A patient who suddenly develops hypotension, loses consciousness, or goes into respiratory distress after a suspected trigger has anaphylaxis until proven otherwise.
Epinephrine dosing
Epinephrine for anaphylaxis is always intramuscular (IM) into the outer mid-thigh — faster absorption than subcutaneous or deltoid injection. Never IV outside a monitored medical setting.
| Patient | Dose | Route |
|---|---|---|
| Adult or child over 30 kg (66 lb) | 0.3 mg | IM, outer mid-thigh |
| Child 15–30 kg (33–66 lb) | 0.15 mg | IM, outer mid-thigh |
| Infant or child under 15 kg (33 lb) | 0.01 mg/kg | IM, drawn in 1 mL syringe |
Auto-injector technique: 1. Remove the safety cap — pull straight off, never grip the tip end. 2. Press the tip firmly against the outer mid-thigh. Through clothing is acceptable. 3. Push firmly and hold for 10 full seconds after the click. 4. Remove straight out. Rub the injection site for 10 seconds. 5. Note the exact time. Save the used device.
Repeat dosing: If symptoms are not improving after 5 minutes, give a second dose. Approximately 25% of cases require more than one dose. A third dose may be given after another 5 minutes if available.
Positioning
- Cardiovascular signs (low BP, faintness): Lay flat with legs elevated 12–18 inches (30–45 cm).
- Airway distress (wheezing, stridor): Allow upright sitting.
- Never allow standing or walking during active anaphylaxis — cardiovascular collapse can occur within seconds.
Airway angioedema
Hoarse or muffled voice signals vocal cord swelling. Stridor (high-pitched crowing on inhalation) means significant airway narrowing — this is the last warning before complete obstruction. Give epinephrine immediately and keep the patient upright. Do not withhold a second or third dose because the patient already received one.
Biphasic reaction — observe for 4–6 hours
A second wave of anaphylaxis occurs in up to 20% of cases, typically within 8 hours but documented as late as 72 hours. After symptoms resolve: - Keep the patient in a supervised observation setting for a minimum of 4–6 hours - Monitor every 30 minutes: breathing, skin, pulse, mental status - Keep epinephrine immediately accessible throughout - If any anaphylaxis symptoms return, treat as a new event
Adjunct — antihistamine: Diphenhydramine (Benadryl) 25–50 mg after epinephrine reduces hive and itch symptoms. It does not treat hypotension, bronchospasm, or airway swelling. Give it after epinephrine, never instead of it.
For grading criteria, auto-injector error prevention, insect sting field protocol, and kit requirements for known-allergy households, see allergic reactions and anaphylaxis.
Medication continuity: the cold chain
The epinephrine you just used for anaphylaxis is a refrigerator-temperature-sensitive drug — and so are insulin, biologics for autoimmune conditions, GLP-1 agonists, and some prescription eye drops. When the power fails, every refrigerator-dependent medication in the household starts a clock. A refrigerator crosses 40°F (4°C) within two to four hours of power loss; food becomes a triage problem inside of four hours; insulin and biologics can degrade silently without changing color, smell, or appearance. The discipline below preserves usable medication through the outage.
The four temperature zones
Every cold-chain item lives in one of four zones. Mixing zones — particularly putting an EpiPen on ice or letting dry ice touch insulin — destroys the drug.
| Zone | Range | What lives here |
|---|---|---|
| Zone 1 — Room temperature | 59–77°F (15–25°C) | In-use insulin and biologics within their labeled window; EpiPen and epinephrine auto-injectors (never refrigerate); most oral medications |
| Zone 2 — Refrigerator | 33–40°F (0.6–4°C); CDC vaccine standard 35–46°F (2–8°C) | Unopened insulin reserve; unopened biologics; GLP-1 agonists (Ozempic, Trulicity, Victoza) before first use; dairy, eggs, leftovers |
| Zone 3 — Freezer | 0°F (-18°C) and below | Long-term food; bulk ice supply |
| Zone 4 — Ultra-cold | -70°C (-94°F) and below | Some mRNA vaccines at the clinic level — not a household concern |
EpiPens belong at room temperature — never in a cooler
Temperatures below 59°F (15°C) degrade epinephrine. The instinct to "protect" an EpiPen by putting it on ice during a hot-weather outage destroys the drug. Store epinephrine auto-injectors at room temperature in an insulated carrying case. If the solution has turned pink or brown rather than clear and colorless, it has degraded — replace it before relying on it.
Insulin and biologics: brand-specific room-temperature windows
Per FDA emergency-storage guidance, unopened insulin stores at 36–46°F (2–8°C) through its labeled expiration. Once a vial or pen is in use, each brand has its own room-temperature stability window — there is no single "insulin room-temperature rule." All windows below apply at room temperature up to 86°F (30°C) maximum. Above 86°F, the window shortens and the product should be protected from heat regardless of brand.
| Brand | Active ingredient | Room-temp window |
|---|---|---|
| Humalog | Insulin lispro | 28 days at ≤86°F (30°C) |
| NovoLog | Insulin aspart | 28 days at ≤86°F (30°C) |
| Lantus / Basaglar | Insulin glargine U-100 | 28 days at ≤86°F (30°C) |
| Tresiba | Insulin degludec | 56 days at ≤86°F (30°C) |
| Toujeo | Insulin glargine U-300 | 56 days at ≤86°F (30°C) |
| Humira (adalimumab) | Biologic | 14 days at ≤77°F (25°C) |
| Enbrel (etanercept), prefilled | Biologic | 30 days at ≤77°F (25°C) |
| Ozempic (semaglutide) | GLP-1 agonist | 56 days at ≤86°F (30°C) |
| Trulicity (dulaglutide) | GLP-1 agonist | 14 days at ≤86°F (30°C) |
Three rules apply regardless of brand:
- Mark the start date on every pen or vial in permanent marker the moment it first reaches room temperature. A pen without a start date has an unknown clock.
- Discard at window end. Do not return room-temperature insulin to the refrigerator and assume the clock resets — it does not.
- Freezing destroys insulin irreversibly. Direct contact with ice or dry ice will freeze insulin and biologics. A frozen-then-thawed vial may look normal — clear, without particles — but it may be partially or fully inactive. Discard any insulin that has been frozen. The same applies to all biologics and GLP-1 agonists.
For biosimilar products (lower-cost alternatives to branded biologics), do not extrapolate from the table above — read the specific package insert. Formulations differ.
Cooler workflow for medications
When power loss is expected to exceed four hours or when the refrigerator has crossed 40°F (4°C):
- Pre-chill the cooler for at least 30 minutes before loading medication. A room-temperature cooler wastes ice warming itself.
- Layer from bottom to top: one inch (2.5 cm) of loose ice or frozen gel packs, a folded cloth or paper-towel barrier, medications in original packaging, another cloth layer, then ice on top. The barrier is mandatory — never let ice contact insulin or biologic vials directly. Direct ice contact freezes the drug and destroys it.
- Target Zone 2: 36–46°F (2–8°C). A digital probe thermometer in the cooler is not optional — verify before closing. If the cooler reads below 33°F (0.6°C), the medication may freeze; add more insulation between ice and meds.
- Keep the cooler closed. Every opening costs 20–30 minutes of cold retention. Designate one household member to manage access.
- Check temperature every 8–12 hours. Block ice lasts 3–5 days in a quality cooler; bagged cubed ice lasts 1–2 days. Fill empty space with water bottles — a full cooler holds temperature longer than a half-full one.
One cooler per job. Medications live in their own small cooler that opens once or twice a day. Food lives in a separate, larger cooler that gets opened more often. Mixing the two guarantees that meal access cycles destroy the medication temperature stability.
A Frio cooling wallet (an evaporative polymer pouch activated by soaking in water for five minutes) maintains insulin at 59–77°F (15–25°C) for approximately 45 hours without electricity. It is Zone 1, not Zone 2 — appropriate for in-use pens during a short outage, not for the unopened reserve that needs to stay refrigerated through its labeled expiration.
Freezer and refrigerator triage
Per USDA FSIS guidance:
- Full freezer: holds 0°F (-18°C) for approximately 48 hours with the door closed.
- Half-full freezer: holds safe temperature for approximately 24 hours with the door closed.
- Refrigerator 4-hour rule: discard perishable refrigerated food (meat, poultry, fish, eggs, dairy, leftovers, cooked grains) that has been above 40°F (4°C) for 4 or more cumulative hours. Hard cheeses, whole produce, and unopened vinegar-based condiments do not require the 4-hour rule.
Refreezing rule: food that still contains ice crystals throughout, or that measures at 40°F (4°C) or below, is safe to refreeze. Food fully thawed above 40°F must be cooked immediately or discarded — never refrozen. Ice cream that has melted past 40°F must be discarded regardless of appearance.
The smell test is not a safety test
Salmonella, Listeria, E. coli O157:H7, and Staph aureus toxin produce no detectable smell or color change. A piece of chicken that smells normal may contain dangerous levels of toxin. Use a thermometer, not your nose. When in doubt, throw it out.
Generator and battery priority for cold-chain loads
When power backup is limited, the cold chain comes first — before lighting, before device charging, before comfort. A spoiled package of chicken is a loss. An insulin-dependent patient with no usable insulin is a medical emergency.
A standard refrigerator draws 300–800 running watts (1,200–2,000 starting watts during compressor cycling); a chest freezer draws 80–150 running watts. A 2,000-watt inverter generator handles both as long as no other high-draw appliance shares the load. You do not need to run the generator continuously: a proven pattern is one to two hours every six to eight hours. Two hours of operation brings a refrigerator from 50°F (10°C) down to 37°F (3°C) and a chest freezer back to 0°F (-18°C), assuming doors have stayed closed between cycles. This cycle extends a 5-gallon (19-liter) fuel supply to four or more days.
Load priority on a limited battery station or small generator:
- Refrigerator (or dedicated medication cooler if that is the medication storage location)
- Chest freezer
- Medical devices with life-safety power requirements (CPAP, nebulizer, oxygen concentrator)
- Communication (phone, weather radio)
- Lighting
- Everything else
Generators outside, always
Carbon monoxide from a generator accumulates to lethal concentrations within minutes inside a garage, shed, or enclosed porch. Place the generator at least 20 feet (6 m) from any window, door, or vent — ideally upwind. This rule is absolute; there are no exceptions.
For the full cold-chain framework — dry ice safe handling, vaccine storage rules, the Frio wallet details, and failure-mode recovery — see cold chain during power outages.
Caregiver coordination and vulnerable household members
Field medicine for trauma is one half of the job. The other half is the operational layer that keeps a household functioning when a primary caregiver is the link between a vulnerable person and survival. Elderly members with cognitive impairment, household members on life-critical medications, residents of assisted-living facilities, and the caregivers themselves all have failure modes that look nothing like a bleeding wound — and that kill just as reliably when missed.
For households with chronic-condition members, infants, elderly, or power-dependent medical devices, the routing in medical-dependent household: routing and first-wave plan takes precedence. The notes below summarize the coordination layer that bridges field-medicine procedures to long-stay caregiving.
Advance-directive instruments — know the four
Four distinct legal instruments govern medical decision-making for an incapacitated adult. They are not interchangeable, and confusion about which document does what is a documented failure mode at the point of care.
| Instrument | What it does | Who signs | Scope |
|---|---|---|---|
| Living Will | Written statement of treatment preferences if the patient cannot communicate | Patient (witnessed/notarized per state) | Guidance to providers; physicians retain clinical discretion |
| Healthcare Proxy (Healthcare Power of Attorney) | Names a specific person to make medical decisions | Patient (witnessed/notarized per state) | Broad — proxy acts from patient's known values, not a script |
| DNR (Do-Not-Resuscitate) | Medical order: do not perform CPR if heart and breathing stop | Patient's physician | Narrow — governs CPR only, not other interventions |
| POLST (Physician Orders for Life-Sustaining Treatment) | Portable physician-signed medical order — same legal weight as any medical order | Patient's physician | Broader than DNR — covers CPR status, level of intervention (comfort care vs. full intervention), and artificial nutrition |
In a crisis, the document that emergency responders act on is the POLST or DNR — both are physician orders. A Living Will and Healthcare Proxy describe preferences and authority but do not directly govern EMS treatment in the field. POLSTs are designed to be portable and immediately actionable; the convention is to store them where emergency responders can find them quickly — the refrigerator door is the standard location.
Practical preparedness for any household with a seriously ill or advanced-age member:
- Confirm which documents exist and are current (executed within the last 3–5 years or after a significant change in health status).
- Ensure the primary caregiver and at least one backup know where each document is stored.
- Keep a copy in the emergency kit.
- If documents do not exist, the conversation is overdue. Many states have standard POLST forms (called MOLST in New York, MOST in South Carolina, DMOST in West Virginia — names vary, substance is consistent) available at no cost through the patient's primary-care physician.
Assisted-living and long-term-care facility evacuation
If a family member lives in a CMS-certified nursing facility, assisted-living community, or skilled nursing facility, federal law governs what that facility must do in an emergency. Under the CMS Emergency Preparedness Rule, 42 CFR 483.73, all CMS-certified long-term-care facilities must maintain an emergency preparedness program with a written plan reviewed annually, a family-notification communication plan, subsistence policies, an emergency power plan, and annual training including tabletop and full-scale exercises.
What families should confirm before an event, not during one:
- Ask the facility director: Where will residents be transferred if this facility evacuates, and how will families be notified? Get the answer in writing.
- Confirm you are on the facility's notification list for your family member; verify the contact number is current.
- Identify the facility's primary receiving site. Know the route.
- Ask what medications and supplies the facility will transport with your family member and what you may need to provide separately.
- Confirm your name (and at least one backup) is on the authorized-release list — many facilities will not release residents to family members during evacuations without documented authorization on file.
For a 72-hour evacuation, facilities typically transport medications and medical records, but you should have independently: a 72-hour supply of life-critical medications in a labeled bag, a copy of the medical-history packet, advance directives and POLST, and comfort items (familiar object, preferred snack, hearing aids and spare batteries).
Note: 42 CFR 483.73 applies to CMS-certified facilities only. Private-pay assisted-living facilities not accepting Medicare or Medicaid may not be subject to the same federal requirements — verify your specific facility's obligations with your state health department.
Caregiver burnout — plan for the predictable failure
A caregiver who reaches collapse is a medical emergency for the person they care for. Sleep deprivation below six hours per night in a sustained event produces measurable cognitive impairment equivalent to alcohol intoxication by day three. Per Johns Hopkins and Cleveland Clinic guidance, watch for:
- Fatigue that does not improve with sleep
- Irritability and mood swings out of character
- Forgetting medication schedules or changes in the patient's condition
- Withdrawal from personal contacts
- Neglecting your own food, hydration, or medical needs
The single most effective intervention is a backup caregiver identified and briefed before the event. This person needs to know: where the medications are, what the schedule is, what to watch for as a missed-dose signal, and who to call if the patient deteriorates. People asked in advance almost always say yes; people asked in the middle of a crisis are harder to reach and slower to mobilize.
Establish a sleep rotation in any event lasting more than 48 hours. When you notice three or more burnout signs simultaneously, contact your backup caregiver and arrange a sleep block within 24 hours. That single action addresses the most operationally critical dimension of burnout.
Field note
A cognitively impaired person who insists they already took their medication may genuinely believe it — and may also be right. Arguing is counterproductive. A laminated daily medication sheet with a checkoff column, restarted each morning, lets a backup caregiver confirm without confrontation. One check mark per dose. No ambiguity.
For the full caregiver framework — fall prevention, dementia routine continuity, mobility-aid power continuity, hearing- and vision-aid backup, and the elder-care preparedness checklist — see elder care and caregiver preparedness.
Pandemic and infectious disease protocols
When a transmissible pathogen is spreading in your area, household management determines how many members get sick and how sick they get.
Quarantine vs. isolation
Quarantine is for people exposed but not yet symptomatic. Isolation is for confirmed or probable cases — anyone symptomatic. They require different room assignments and different caregiver protocols. Confusing them creates household risk.
Home isolation room
- Choose a room with a closing door. Attached bathroom is ideal.
- Place a box fan exhausting outward in the window — this creates negative pressure that draws air into the room rather than pushing room air out.
- Seal the gap under the door when the fan is running.
- Stock the room completely before the sick person enters: thermometer, water, medications, waste container. The sick person should not need to leave for supplies.
PPE donning and doffing sequence
Most personal protective equipment (PPE) exposure events happen during doffing, not during patient care. Contaminated equipment touching the wearer's face is the primary vector.
Donning order (outside the room): 1. Hand hygiene 2. Gown 3. N95 with seal check 4. Eye protection (goggles or face shield) 5. Hand hygiene 6. Gloves last — they contact contaminated surfaces directly
Doffing order (in a transition zone outside the door): 1. Remove gloves inside-out — discard without touching the outside 2. Hand hygiene 3. Remove gown rolling inward — contaminated outer surface folds in on itself 4. Hand hygiene 5. Remove eye protection from the sides or headband — never touch the front face surface 6. Hand hygiene 7. Remove N95 by lifting the bottom strap over the head first, then the top strap 8. Hand hygiene
Doffing errors are the primary exposure vector
Touching the face between removal steps is the most common failure mode. Practice the sequence with non-contaminated PPE until each transition is automatic. A contaminated glove that touches your eye undoes everything the rest of the PPE accomplished.
Escalation criteria
Move to emergency care immediately if any single criterion is met: - Severe shortness of breath at rest — cannot complete a sentence - Oxygen saturation below 94% on pulse oximeter (below 90% is immediately life-threatening) - Respiratory rate above 24 breaths per minute at rest - Fever above 103°F (39.4°C) unresponsive to medication within 2 hours - New confusion or altered mental status - Cyanosis — blue or gray lips, fingernails, or skin

Field hygiene: preventing the second crisis
After trauma and illness are managed, the next threat in a prolonged emergency is hygiene-related disease. Cholera, typhoid, and norovirus become primary killers faster than most people expect when sanitation infrastructure fails.
Hand hygiene — seven critical moments
These seven moments must not be skipped:
- After using the toilet or latrine
- Before preparing food
- Before eating
- Before any wound care
- After handling human or animal waste
- After caring for a sick person (before and after)
- After coughing, sneezing, or blowing your nose
No-power handwashing station
Puncture a small hole in the cap of a 1-gallon (3.8-liter) jug of clean water. Hang it over a basin. Add soap on a cord. Refill daily. This single setup replaces the running water tap for all critical handwashing moments during a power outage.
Wound prevention through hygiene
Wounds irrigated within the first hour have significantly lower infection rates. The hygiene habits that prevent contamination from entering wounds — washing hands before every wound care contact, keeping dressings clean and dry, and managing the environment — are as important as the irrigation volume itself. See field hygiene for waste disposal, food handling, vector control, and group hygiene protocols that prevent the second wave of casualties.
Environmental emergencies
Heat, cold, and fluid loss are as lethal as any wound — and more likely to sneak up on a caregiver who is focused on trauma management. All three share a common failure mode: the problem is obvious in retrospect and invisible until it isn't.
Heatstroke
Heat illness runs a spectrum. Heat exhaustion — heavy sweating, weakness, nausea, pale clammy skin — is serious but manageable with shade, oral fluids, and cooling. Heatstroke is the emergency: it is defined by altered mental status (confusion, combativeness, agitation, or unconsciousness) in a hot environment. Do not wait for a thermometer reading to begin cooling if mental status is abnormal.
First-line cooling: cold water immersion. Immerse the patient in cold water 35–59°F (2–15°C) up to the neck. This is the fastest field method — faster than ice packs, fans, or wet cloths alone. Target cooling rate is 0.15°C per minute. Stop immersion when rectal temperature reaches 102°F (38.9°C) to prevent overshoot. If immersion is impossible, strip the patient to skin, apply continuous cold water over the body, fan aggressively, and place ice packs at the neck, armpits, and groin simultaneously.
Cool first, transport second
Organ damage accumulates every minute the patient stays hot. Begin cooling before calling for evacuation, not after. A patient who cools before arrival has significantly better outcomes than one who arrives hot.
For the full heat illness spectrum, exertional vs. classic heatstroke distinctions, and complication monitoring, see heatstroke recognition and cooling.
Hypothermia
The Swiss staging system classifies hypothermia by clinical signs, not thermometer readings — because in field conditions you often have neither. The key transition is between stages:
- HT I (90–95°F (32–35°C)): Shivering, alert and oriented. Passive rewarming — dry clothes, insulation, shelter from wind — is usually sufficient.
- HT II (82–90°F (28–32°C)): Shivering has stopped. The patient is confused and cannot walk reliably. This stage is lethal without active rewarming and evacuation. A patient who has stopped shivering in cold conditions is in HT II until proven otherwise.
- HT III–IV (below 82°F (28°C)): Unconscious or no detectable vitals. Check pulse for a full 60 seconds before concluding absence — hypothermic vital signs are very slow. Continue cardiopulmonary resuscitation (CPR) if no pulse is found; the axiom is "not dead until warm and dead."
Two hazards require deliberate technique. Afterdrop: warming the limbs before the core drives cold peripheral blood back toward the heart; always heat the core first (axillae, neck, groin) and keep the patient horizontal. Ventricular fibrillation risk: below 86°F (30°C) the heart is electrically unstable — rough handling, sudden position changes, or chest percussion can trigger VF that will not respond to defibrillation until the patient is rewarmed. Handle HT II–IV patients with deliberate gentleness.
For the four-question field staging sequence, hypothermia wrap construction, and rescue collapse prevention, see hypothermia staging and rewarming.
Dehydration
Urine color is the most practical field assessment tool. Pale yellow (color 1–2) means well hydrated. Dark amber (color 5–6) means dehydrated — begin oral rehydration solution (ORS) now. Brown or orange (color 7–8) is a severe dehydration emergency.
Plain water alone does not correct dehydration when electrolytes have been lost through sweat, vomiting, or diarrhea. The WHO oral rehydration salts formula per 1 liter of clean water is: 2.6 g sodium chloride (slightly under ½ tsp table salt) + 13.5 g glucose (6 tsp sugar) + 1.5 g potassium chloride. When potassium chloride is unavailable, the salt-and-sugar shortcut handles the most critical components. Do not substitute plain water — hyponatremia (low sodium from overdrinking plain water) presents with confusion and nausea that can mimic dehydration and worsen with more plain water.
When the patient is vomiting: large volumes cannot be kept down. Give 5 mL every 1–2 minutes by syringe or spoon — this rate is almost always tolerated and adds up to meaningful rehydration volume over an hour.
Field note
Dehydration compounds every other emergency on this page. A dehydrated patient bleeds worse (impaired clotting), cools faster (reduced cardiac output), and overheats faster (impaired sweating). Maintaining hydration throughout a prolonged emergency is not comfort care — it is mission-critical.
For severity grading, skin turgor assessment, pediatric dosing, and the rectal proctoclysis fallback when oral route fails, see dehydration assessment and rehydration.
Putting it together: the field assessment sequence
When you encounter a casualty, move through this sequence:
- Scene safety: Is it safe to approach? Active hazards kill rescuers.
- Massive hemorrhage: Life-threatening external bleeding? Tourniquet or pack immediately.
- Airway: Is the patient speaking? Speaking = patent airway. Unconscious = check and open.
- Respiration: Adequate rate and depth? Look for paradoxical chest movement, sucking chest wounds.
- Circulation: Pulse character — rate and strength. Signs of shock?
- Hypothermia: Cover the patient. Blanket, mylar, clothing. Every patient in shock is at risk.
- Wound care: After hemorrhage is controlled, irrigate and dress wounds.
- Fractures: CSM check, splint, recheck CSM, monitor during transport.
- Infection watch: Begin the daily STONES inspection from day one. Mark redness baselines.
- Allergic response: Know the household allergy history before a crisis. Know where the epinephrine is.
- Environmental threats: Monitor everyone's urine color, hydration intake, and thermal status — dehydration, heatstroke, and hypothermia can develop quietly in caregivers as well as casualties.
The difference between a wound that heals and one that kills is usually not resources. It is discipline: the irrigation that happens on time, the tourniquet that is tightened past resistance, the red streak that gets marked and monitored at 2-hour intervals instead of noticed the next morning. None of these skills require a medical degree. All of them require deliberate practice before the moment they are needed.
After the immediate crisis: the recovery arc
Help arriving is not the end of the medical phase. The first 72 hours after the immediate threat passes — when you return to a damaged home, restart utilities, and begin documenting losses — concentrate hazards that injure people who survived the original event. Burns from flood-energized wiring, carbon monoxide poisoning from generators placed too close to the house, mold-driven respiratory crises within weeks, and contractor fraud are the recovery-phase failure modes that play out after the field-medicine work is done. The 4-phase framework below structures the medical and operational arc from immediate safety to financial recovery.
Phase 1 — Immediate safety (0–24 hours)
Return home only when local emergency management or law enforcement has lifted the evacuation order. Social-media reports and visual assessment from a distance do not substitute. When the official all-clear is issued:
- Photograph the exterior before entering. Walk the full perimeter if accessible. Photograph all four sides, the roof from ground level, and any visible foundation. Timestamps matter.
- Smell at the threshold. Crack the door an inch and pause. Gas odor — sulfur or rotten egg — means stop. Move upwind and call your gas company from a safe distance. Do not operate any electrical switch.
- Check utility meters before restoring service. Visible damage to the electric meter (melted insulation, scorch marks, water intrusion) means do not restore power — call the utility. Same rule for the gas meter and regulators.
- Ventilate before extended interior time. Open windows. Do not use open flame or cigarettes until the structure is confirmed gas-free.
- Do not turn power on in a flood-damaged structure until a licensed electrician has inspected all wiring. Submerged electrical panels require replacement, not just drying. Energized damp insulation and live outlets at floor level are the most common electrical-injury pattern in post-flood return-home incidents.
| Utility | Who clears it | Do not restore until |
|---|---|---|
| Natural gas | Your gas utility | Gas company technician inspects meter and shutoff |
| Electricity | Licensed electrician | All wiring inspected; panel dry; no submersion evidence |
| Water | Your municipality | Boil-water advisory lifted; pressure restored |
| Propane | Propane supplier | Supplier inspects tank and regulator |
Generator placement is a medical issue, not just an electrical one
Carbon monoxide poisoning from generators is the leading cause of fatality in the days after a major disaster. CO accumulates to lethal concentrations within minutes inside a garage, shed, or enclosed porch. Place the generator at least 20 feet (6 m) from any door, window, or vent — ideally upwind. Battery-powered CO alarms in every sleeping area are not optional during generator use. CO has no smell. The first symptom in an asleep person may be the last.
Phase 2 — Damage assessment and the mold 48-hour window (24–72 hours)
A homeowner's structural walkthrough is a triage tool, not an engineering assessment. Its purpose is to identify conditions that require a licensed structural engineer before you proceed. Foundation cracks wider than 1/4 inch (6 mm), visible foundation shift, multiple racked doors on the same wall, ceilings sagging more than 1/8 inch (3 mm) at corners, and any visibly bowing wall are professional territory. In many jurisdictions the municipal building department deploys ATC-20 rapid-evaluation teams to disaster zones at no cost — ask your local emergency management office.
Document before you touch anything. Insurance adjusters and FEMA inspectors work from evidence, not from your description. Video walkthrough first, narrating as you go ("northeast corner, carpet has standing water, baseboards buckled, drywall waterline approximately 18 inches above the floor"). Individual photos of every significant damaged item, plus the serial-number plate. Written room-by-room inventory: item, age, approximate purchase price, condition before the event. Send every photo to a cloud account or email immediately — a phone that is then damaged or stolen still leaves you with timestamped documentation.
Mold colonizes wet building materials within 24 to 48 hours of water intrusion, per EPA guidance. In warm humid conditions the window closes faster. The 48-hour window is the most time-critical recovery decision after Phase 1 utility clearance.
Within the first 48 hours:
- Remove standing water with a wet-dry vacuum, mop, or pump. Do not wait for a restoration contractor.
- Remove soaked carpet, carpet padding, and saturated drywall sections. These cannot be adequately dried and must be discarded if wet more than 48 hours.
- Run dehumidifiers and fans to accelerate drying — but only if mold has not yet started growing. If you can see fuzzy or discolored surface growth, do not run fans. Running fans in a mold-active environment distributes spores to unaffected rooms.
- Target indoor humidity below 50%.
- Leave interior doors and cabinet doors open for airflow.
The EPA's residential mold-remediation size thresholds:
- Under 10 sq ft (0.9 m²) of contiguous affected material: homeowner remediation is appropriate. Wear N95 respirator, goggles, and gloves.
- 10–100 sq ft (0.9–9.3 m²): consult or hire a professional with mold remediation experience. Single-layer polyethylene containment required.
- Over 100 sq ft (9.3 m²): full professional remediation. Double-layer containment, decontamination chamber, and HEPA-filtered negative air machines required.
Do not run the HVAC after a flood
If your HVAC system ran during or after a flood event, spores may have entered the ductwork. Do not run HVAC until the system has been inspected and cleaned. A contaminated HVAC system distributes spores throughout every room in the house.
Phase 3 — Insurance, FEMA Individual Assistance, and contractor vetting (72 hours to 30 days)
Contact your insurance carrier the same day you have documented losses. Most policies require "prompt notice" of loss; delays can complicate claims. Get a claim number and the assigned adjuster's name. Do not sign any paperwork at the initial visit without reading it — adjusters represent your insurer's interests.
Understand whether your policy pays Actual Cash Value (ACV) — what the item was worth on the day of loss with depreciation — or Replacement Cost Value (RCV) — what it costs to buy an equivalent item new today. A 5-year-old couch that cost $2,000 new might be worth $800 under ACV. Most homeowner policies pay ACV unless you specifically carry an RCV endorsement. Check your policy before assuming. Standard homeowner's insurance does not cover flood damage — flood coverage requires a separate NFIP or private flood policy.
Apply for FEMA Individual Assistance within 60 days of the Presidential Disaster Declaration. Register at DisasterAssistance.gov, the FEMA App, or 1-800-621-3362 (TTY 1-800-462-7585), 6 a.m.–10 p.m. CT. The 2024 reforms allow late applications for an additional 60 days without justification, but do not wait — apply as early as possible. Have ready:
- Social Security numbers for every household member
- Pre-disaster address and current temporary address
- Phone number and email that work right now
- Insurance policy number and your insurer's claims phone number
- Bank account routing and account number (for direct deposit)
- A one-paragraph description of losses, drawn from your damage walkthrough notes
- Proof of ownership (deed, mortgage statement, property tax bill) or proof of occupancy (lease, utility bill)
FEMA's Individuals and Households Program has two assistance buckets, each with a separate FY2025 maximum: Housing Assistance ($43,600/household) for temporary housing, home repair, and home replacement; Other Needs Assistance ($43,600/household) for personal property, medical, dental, funeral, transportation, and moving costs. These are program ceilings, not entitlements — awards are based on documented need. FEMA assistance is meant to bridge gaps to safe, sanitary, functional housing, not to fully fund reconstruction. For major reconstruction costs, the SBA Disaster Loan program provides low-interest loans to homeowners (not just businesses) up to $500,000 for real property.
Renters are eligible for FEMA IA, but the flow differs. Apply for Other Needs Assistance for personal property loss and FEMA Housing Assistance for temporary rental assistance — the structural claim on the building itself belongs to the landlord. Proof of occupancy (a lease, a utility bill in your name) replaces proof of ownership.
Phase 4 — Contractor fraud avoidance
The FTC, DOJ, and CFPB jointly warned in October 2024 that disaster-related fraud jumps significantly in the weeks after major events. The pattern is consistent: door-to-door contractors arrive in hard-hit areas within days, quote a fair-sounding price, require full or large up-front payment, and either do substandard work or disappear with the deposit.
Red flags that indicate a predatory contractor:
- Arrives unsolicited at your door (the "storm chaser" model)
- Cannot provide a local physical address or local license number
- Asks for full payment, or more than one-third, before work begins
- Pressures you to sign quickly ("I can only hold this price today")
- Offers to handle your insurance claim for you, including asking you to sign your insurance check over to them
- Wants payment by cash, wire transfer, gift card, cryptocurrency, or payment app
- Has no written contract, or offers a contract with no start and completion dates
Verification before signing:
- Verify the license directly through your state contractor licensing board's online lookup tool. Do not rely on a card or verbal statement.
- Verify insurance. Request a certificate of insurance showing general liability and workers' compensation. Call the issuing insurance agency to confirm the certificate is current — certificates can be forged.
- Get at least two competing estimates for any significant work. Post-disaster labor and materials prices inflate rapidly; multiple estimates protect against predatory pricing.
- Never pay more than one-third up front. A reasonable schedule is one-third at signing, one-third at a defined milestone, one-third at completion and your satisfaction.
- Get a written contract specifying scope, materials, start date, projected completion date, payment schedule, and what happens if work is delayed.
- Pay by check (payable to the company name, not an individual) or credit card. Cash, wire, gift card, and cryptocurrency leave no recourse if the contractor fails to perform.
If you believe you have been defrauded, report to the FTC at ReportFraud.ftc.gov, your state attorney general's consumer protection division, and your state licensing board.
Field note
Post-disaster mental-health responses — intrusive thoughts, hypervigilance, sleep disruption, irritability — are normal reactions to abnormal events. They become a clinical problem when they persist beyond a few weeks without improvement; that is the point to seek professional support. FEMA's Disaster Distress Helpline (1-800-985-5990 or text "TalkWithUs" to 66746) provides 24/7 crisis counseling for disaster survivors.
