First aid when the ambulance is two hours away

Most first-aid advice quietly assumes an ambulance is coming in eight minutes. In an outage, in a rural house, in a storm, it is not. That single change — no ambulance, no phone, no car — reorders what you do first, and it makes three cheap skills worth more than everything else in the kit.

The order of operations

Not ABC in the abstract — the order that matches what actually kills people before help arrives:

1. Bleeding — a limb bleed can kill in minutes. This is first, every time.
2. Breathing — airway and positioning. If they are not breathing, start CPR and do not stop to look for a pulse you are not trained to find.
3. Warmth — in a cold house the injury is not the only threat; a cold patient bleeds and clots worse and can die of exposure while you treat a cut.
4. Infection — the slow one, and the one that kills on day four rather than day one.

Bleeding: pressure, pack, tourniquet

This is a summary, not training. Reading it does not make anyone competent, and a tourniquet is a skill you practise on a limb simulator before you need it, or not at all.

• Direct pressure. Press hard on the wound with a dressing, a clean cloth, or a bare hand, and do not lift to look. Lifting restarts the bleeding. If it soaks through, add layers on top — never remove the soaked ones. Hold well past the point you want to stop.
• Wound packing. For deep bleeding in a limb, groin, armpit or neck, surface pressure may never reach the source. Push gauze firmly into the wound to the bottom, fill it, then press down hard over the packed wound and hold. It hurts, and it is meant to.
• Tourniquet. For life-threatening limb bleeding that pressure and packing have not stopped: high and tight, above the wound, over clothing. Never over a joint — if the wound is at the elbow or knee, go above the joint. Write the time on the limb or on tape. Do not loosen it "to let blood through".

Infection: the day-four killer

Scarce clean water, dirtier hands, more manual work — an outage is an infection factory. Irrigate with the cleanest water you have, 250 mL minimum per wound, under pressure from a squeeze bottle. Bottled water beats well water; well water beats snowmelt. Remove what you can see at the surface; never dig blind into a deep wound. Cover with a clean dressing and change it daily — a wet dressing left on is worse than none.

Check at 24 hours and again at 48 for the four signs: increasing pain, spreading redness, warmth, pus — plus fever and red streaks tracking up the limb. With no phone and no car, any of those is an emergency today, not tomorrow. This is the part where waiting is the mistake.

Cold injuries: gentle, and trunk before limbs

Two rules save lives. Handle a hypothermic person gently — rough handling of a cold heart can trigger a fatal arrhythmia. And warm the trunk, not the limbs, because warm limbs push cold blood back toward the heart. Blankets, body-to-body heat, warm packs to neck, armpits and groin. No alcohol, no rubbing, no hot bath.

And the rule that gets forgotten: nothing by mouth — no fluid, food or medicine — for anyone drowsy, confused or unconscious. A cold, dulled patient cannot protect their airway, and aspiration is a faster way to die than the hypothermia you were treating.

Frostbite is white, waxy, numb skin that does not rebound when pressed. Never rub it — rubbing destroys the ice crystals inside the cells. Warm water at 37–39 °C for 20–30 minutes; it will hurt badly as feeling returns. No dry heat, no hair dryers. If the part might refreeze, do not thaw it — thaw-refreeze is far worse than staying frozen to hospital.

The recipe that prevents the most deaths

Diarrhoeal illness kills through dehydration, and the treatment is salt, sugar and clean water in the right ratio. The oral rehydration solution used by health agencies is 1 litre of clean water, 6 level teaspoons of sugar, and half a level teaspoon of salt. Stir until dissolved. Sip it. Do not add more salt to "make it work faster" — too much salt makes it worse, and it is the one ingredient small errors matter on.

Do not give ORS to someone who is drowsy, vomiting continuously, or unable to swallow — that is a medical emergency, not a recipe problem.

The medication problem, which is the real one

Almost every first-aid chapter skips this, and it is more likely to matter to a household than any wound. Aim for 14 days of every chronic medication, not 3. It is achievable and almost nobody does it.

• Know the emergency-supply route before you need it. Ontario pharmacists can provide an emergency supply when a prescriber is unavailable — but that authority excludes narcotics and controlled substances, which is exactly the class where an interruption is most dangerous. For those, the plan is a prescriber's written plan and a real buffer, not a phone call.
• Keep a printed one-page medication list — drug, dose, frequency, prescriber, pharmacy and phone — in the kit and photographed on two phones. In a hospital in another town, that page is worth more than anything else you own.
• What must not freeze: insulin is ruined by freezing even after it thaws (keep above 0 °C); epinephrine auto-injectors are ruined too and must not be refrigerated or frozen — a unit left overnight in a −25 °C car is dead. Replace it, do not carry it and hope.
