First aid is the provision of initial care for an illness or injury. It is usually performed by non-experts (or sometimes by an expert in case of an emergency), but trained personnel to a sick or injured person until definitive medical treatment can be accessed. Certain self-limiting illnesses or minor injuries may not require further medical care past the first aid intervention. It generally consists of a series of simple and in some cases, potentially life-saving techniques that an individual can be trained to perform with minimal equipment. First aid is basic knowledge about how to help people who are suddenly sick (illnesses) or hurt (injuries or body damage). For example, first aid is used at accidents to help an injured person until he receives medical treatment (help by doctors, nurses or ambulance paramedics). First aid is also used to help people who suddenly become sick, until help arrives or they can be taken to medical care. A person does not need a lot of equipment to give first aid. A package of stuff useful to give first aid is called a first aid kit. Lives can be saved even without a first aid kit. First aid can be done just about anywhere. In places far from hospitals, first aid may be the only help possible until the person can be taken to a hospital or clinic.
