First aid

First aid is the first and immediate assistance given to any person suffering from either a minor or serious illness or injury,with care provided to preserve life, prevent the condition from worsening, or to promote recovery.

It includes initial intervention in a serious condition prior to professional medical help being available, such as performing cardiopulmonary resuscitation (CPR) while waiting for an ambulance, as well as the complete treatment of minor conditions, such as applying a plaster to a cut.

First aid is generally performed by someone with basic medical training. Mental health first aid is an extension of the concept of first aid to cover mental health,^[2] while psychological first aid is used as early treatment of people who are at risk for developing PTSD.^[3] Conflict First Aid, focused on preservation and recovery of an individual’s social or relationship well-being, is being piloted in Canada.

There are many situations that may require first aid, and many countries have legislation, regulation, or guidance which specifies a minimum level of first aid provision in certain circumstances.

This can include specific training or equipment to be available in the workplace (such as an automated external defibrillator), the provision of specialist first aid cover at public gatherings, or mandatory first aid training within schools.

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.
