First Aid Fundamentals

In the absence of hospitals, first aid becomes primary care. The skills that prevent a minor injury from becoming fatal - stopping bleeding, maintaining an airway, treating shock - are learnable by anyone and require no equipment to be effective.

Key Concepts

• —The primary survey (ABCs): in any emergency, assess Airway, Breathing, and Circulation in that order before any other intervention; a blocked airway kills in four minutes while a broken leg does not.
• —Hemorrhage control: direct firm pressure held for a minimum of ten minutes without lifting the dressing controls the vast majority of external bleeding; tourniquets are for life-threatening limb hemorrhage only.
• —Shock recognition and treatment: pale, cold, clammy skin with rapid weak pulse and altered consciousness indicates shock; lay the patient flat, elevate legs if no spinal injury is suspected, and keep warm.
• —Wound cleaning: the most important infection-prevention step after bleeding control is irrigation with large volumes of clean water under pressure; use a syringe or squeeze bottle to flush debris from the wound.
• —Fracture management: immobilizing a fracture in the position found using improvised splints (straight sticks padded with cloth) relieves pain and prevents further injury during transport.

Practical Guide

1. 1.Learn and practice the primary survey until it is automatic: approach a casualty, shout to assess consciousness, tilt the head to open the airway, look and listen for breathing, and check for major bleeding - all within 30 seconds.
2. 2.Apply direct pressure to bleeding wounds using the cleanest cloth available, held firmly without removing; add more cloth on top if blood soaks through - removing the first layer disrupts clot formation.
3. 3.Apply a tourniquet for arterial bleeding from a limb only when direct pressure fails or is impossible; place 5-8 cm above the wound, tighten until bleeding stops, note the time, and do not remove it until definitive care is available.
4. 4.Treat shock by laying the patient on a flat surface, elevating the feet 20-30 cm (unless head, chest, or abdominal injury is suspected), covering with a blanket, and providing sips of oral rehydration solution if conscious.
5. 5.Clean wounds by removing visible debris with clean tweezers, then irrigating with at least 500 ml of clean water through a syringe or improvised pressure device; this single step dramatically reduces infection rates.
6. 6.Splint fractures using padded sticks or boards that extend past the joint above and below the break; secure with bandages or strips of cloth, checking circulation (capillary refill, feeling in fingers/toes) before and after.
7. 7.Maintain a community first aid kit with at minimum: cloth bandages, safety pins, clean thread and a needle, tweezers, a razor blade, oral rehydration salts, antiseptic solution, and a written first aid reference.
