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.

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.

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 (32–35°C / 90–95°F): Shivering, alert and oriented. Passive rewarming — dry clothes, insulation, shelter from wind — is usually sufficient.
HT II (28–32°C / 82–90°F): 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 28°C / 82°F): 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.
