Definition and purpose of first aid

Summary

First aid is the first and immediate assistance given to someone with a medical emergency. Its purpose is to preserve life, prevent the condition from worsening, and support recovery until professional medical services arrive. It is typically provided by people with basic first response training, and the concept also extends to areas such as mental health first aid and psychological first aid. Aims of first aid focus on three main outcomes: preserving life, preventing further harm, and promoting recovery. Because emergencies can threaten both life and mobility, responders follow structured priorities and protocols. Common approaches include the ABCDE framework (Airway, Breathing, Circulation, Disability, Exposure) and CPR-focused sequences such as CABD (Circulation/Chest compressions, Airway, Breathing/Rescue breaths, Defibrillation). First aid is not a substitute for medical treatment, but it relies on common-sense decisions and appropriate actions to reduce risk and improve outcomes. First aid is required in many situations, including bleeding, cardiac arrest, choking, diabetes emergencies, drowning, heart infarction, and stroke. Many countries also set minimum first-aid provisions through laws, workplace requirements, and training expectations. Over time, first aid has been formalized through history and organized services, including military care systems and major humanitarian organizations such as the Red Cross and Red Crescent.
