Definition of first aid

First aid is the immediate assistance given to any person suffering a serious illness or injury with care provided to preserve life, prevent the condition from worsening, or to promote recovery. First aid is generally performed by someone with basic medical training. First aid, however, does not necessarily require any particular equipment or prior knowledge, and can involve improvisation with materials available at the time, often by untrained people.

The primary goal of first aid is to prevent death or serious injury from worsening. Another aim of first aid is to save lives and minimize the threat of death and to further prevent this, we move patient away to prevent any further cause of harm, and applying first aid techniques to prevent worsening of the condition, such as applying pressure to stop a bleed becoming dangerous.

First aid also involves trying to start the recovery process from the illness or injury, and in some cases might involve completing a treatment, such as in the case of applying a plaster to a small wound. First aid is not medical treatment and cannot be compared with what a trained medical professional provides. First aid involves making common sense decisions in best interest of an injured person.
