First aid is the helping behaviours and initial care provided for an acute illness or injury.
First aid can be initiated by anyone in any situation.
A first aider is someone trained in first aid who should :
recognise, assess, and prioritise the need for first aid
provide care by using appropriate competencies
recognise their own limitations, and seek additional care when needed.
The goals of first aid are to preserve life, alleviate suffering, prevent further illness injury, and promote recovery.
