First aid: immediate care for sudden illness and injury
First aid is the prompt, temporary care given to someone who is injured or suddenly ill. This article explains principles, common techniques, kit contents, history, and when to call for professional help.
First aid is the immediate assistance provided to a person who has become suddenly ill or sustained an injury. It covers simple interventions that can be performed with minimal equipment to preserve life, reduce pain, prevent the condition from worsening, and promote recovery. First aid applies across many situations—from workplace accidents to sports injuries and unexpected medical events—and is meant to bridge the period between the onset of a problem and the arrival of professional medical care such as doctors or nurses health practitioners or an ambulance service.
Common conditions that benefit from first aid include a range of illnesses sudden medical events and physical injuries trauma such as cuts, burns, fractures, or unconsciousness. First aid is often delivered at the scene of an accident and can be crucial in places far from hospitals or emergency departments. In many communities, clinics and local health centres and organised services support first-aid training and resources.

10 ImagesBasic principles and priorities
Most systems of first aid follow the same priorities: ensure the scene is safe, assess the casualty's level of response, and manage the most life-threatening problems first. A widely used sequence of priorities is: danger, response, airway, breathing and circulation. In cardiopulmonary resuscitation (CPR) guidance the order is sometimes summarized as C-A-B (compressions, airway, breathing), reflecting the emphasis on restoring circulation when the heart has stopped.
Typical interventions and examples
- Control severe bleeding with direct pressure and dressings.
- Perform CPR and use an automated external defibrillator where available until emergency services arrive.
- Immobilize suspected fractures and support injured limbs to limit further damage.
- Treat burns with cool running water and cover with a clean dressing.
- Manage allergic reactions, including using an epinephrine auto‑injector when prescribed.
These actions are intended as immediate steps, not as definitive treatment. Emergency medical dispatchers often provide telephone guidance to bystanders, telling them which actions to take until an ambulance reaches the scene. In many regions callers to emergency numbers receive basic instructions that can include how to perform hands‑only CPR and how to control bleeding.
Equipment and first aid kits
A basic first aid kit contains items such as sterile dressings, adhesive bandages, adhesive tape, gloves, scissors, antiseptic wipes, triangular bandages, and simple tools like tweezers. While kits make care easier and more hygienic, knowledge and willingness to act are the most important elements; improvised materials can be effective in emergencies.
Origins, training and legal considerations
Modern civilian first aid developed alongside organised medical and relief movements in the late 19th and early 20th centuries, promoted by organisations such as the Red Cross and St John Ambulance. Training courses vary from short awareness sessions to certified programs that teach CPR, automated external defibrillator (AED) use, and extended first aid skills. Many countries also have legal protections, commonly called Good Samaritan laws, that encourage bystanders to assist without fear of routine civil liability—though exact protections vary by jurisdiction and responders should be aware of local rules.
First aid is a practical skill with wide social value. It reduces preventable deaths, limits complications from injury and illness, and empowers communities to respond effectively until professional care in hospitals or clinics is available.
