First aid is the method of providing immediate and preliminary help in case of an illness, injury, or accident. A person administering first aid might not be an expert. The idea is to provide quick help to a victim before expert medical help can be obtained.
Everyone should learn first aid training in life so that they can help anyone in an emergency. First aid can help save a person's life in the event of an accident. First aid techniques can be performed without equipment.

The most important first aid techniques include bandaging, checking for extra bleeding, helping the person breathe properly if choking, minimizing pain in the event of a fracture, etc.

All techniques are practical emergency applications and are not intended as a substitute for suitable medical care or treatment. Many people have experience bandaging and controlling bleeding, but this is not a substitute for proper first aid training.
Adequate training is needed so that a person can actually help in a life-saving situation. Sometimes first aid care is sufficient for a person injured in an accident and no further medical care is required.
However, this requires adequate first aid. The goal of first aid is also to ensure that a person who is seriously injured in an accident remains alive so that an ambulance can reach the scene and adequate medical care can save the victim's life.
