Medical Preparedness and Field First Aid
Educational information only — NOT medical advice and not a substitute for certified training or professional care. Take an in-person first-aid course; skills practiced under supervision are what actually work in a crisis. In any real emergency, contact emergency services (112 in Europe) if at all possible.
Training beats gear
Priority order: a certified first-aid/CPR course, then a wilderness first aid course if you spend time remote, then gear. An untrained person with a full trauma kit is less capable than a trained one with a bandana.
The home kit, by layer
Boo-boo layer (used weekly): adhesive bandages in sizes, blister plasters, antiseptic solution (povidone-iodine or chlorhexidine), tweezers (splinters, ticks), small scissors, tape, burn gel, saline pods for eye and wound rinsing.
Wound layer: sterile gauze pads and rolls, elastic (compression) bandages, non-adherent dressings, wound-closure strips, larger dressing pads, nitrile gloves in quantity, irrigation syringe (clean water under pressure is the best wound cleaner), triangular bandages (sling, tie, padding).
Trauma layer (train before you buy): pressure bandage ("Israeli" style), hemostatic gauze, commercial tourniquet (know current protocols — applied high and tight for life-threatening limb bleeding that pressure cannot stop; note the time), chest seal, space blankets (hypothermia kills trauma patients), headlamp, trauma shears.
Comfort/illness layer: oral rehydration salts (see below), electrolyte tablets, thermometer, common over-the-counter medicines you already use — pain/fever reducers, antihistamines, anti-diarrheal, antacids — stored per label and rotated; personal prescription medicines with the largest buffer your prescriber and law allow (discuss an emergency supply with your doctor; running out of daily medication is the most likely medical crisis in any prolonged disruption).
Skills that carry the most weight
- Severe bleeding, deep cuts, and wounds: direct, hard pressure on the wound with anything at hand beats searching for perfect gear. Elevate, keep pressing, do not peek. Tourniquet only for limb bleeding that pressure cannot control.
- Treating a cut or wound when no doctor or clinic is available: clean early and thoroughly — irrigate with copious clean (drinkable) water, remove debris, dress, change dressings daily, watch for infection: spreading redness, heat, swelling, pus, red streaks, fever. Infection signs = seek professional care with urgency; this is where field medicine ends.
- Burns: cool with running cool (not ice) water for 20 minutes, then cover loosely with clean non-fluffy dressing. Large, deep, facial, genital, or circumferential burns are emergencies.
- Diarrhea and vomiting (adult or child), off-grid with no doctor: the killer is dehydration, and children dehydrate fastest. WHO-style oral rehydration: 1 litre safe water + 6 level teaspoons sugar + 1/2 level teaspoon salt, sipped constantly; continue feeding children. Strict hand and water hygiene protects the rest of the household.
- Sprains/strains: rest, ice/cool, compression, elevation; buddy-tape fingers/toes; improvised splints pad the limb in the position found.
- Hypothermia and heat illness: covered in the cold-weather and water chapters — recognize early, act early.
- Tick bites (check skin after every walk in forest, brush, or tall grass): what to do about a tick bite: remove the tick promptly with fine tweezers gripping at the skin, steady straight pull, no twisting or burning; disinfect; note the date and watch for expanding rash or flu-like symptoms in following weeks — these warrant medical attention.
Dental and eyes
A dental first-aid kit (temporary filling material, clove oil, dental wax) turns a screaming toothache into a manageable wait. Spare prescription glasses in the kit — an old prescription beats no vision; consider one pair in the Faraday/document bin.
Hygiene as medicine
In every historical grid-down event, hygiene-related illness dwarfed injury: handwashing, safe water, safe food handling (cook thoroughly, keep raw and cooked separate, no room-temperature leftovers beyond 2 hours), and sanitation discipline are the highest-yield "medical" preparations that exist.
