What is the definition of first aid?

First aid is defined as the immediate medical care provided to an injured or ill person before professional medical assistance arrives. This definition emphasizes the urgency and the initial response required in emergency situations where quick action can make a critical difference in the victim's outcome.

The focus on "immediate" care highlights the importance of addressing injuries or illnesses right away, as delays can worsen a person's condition. This also distinguishes first aid from other types of medical care, such as long-term treatments for chronic illnesses or preventive measures aimed at avoiding injuries. Additionally, while mass casualty responses may involve first aid, they are broader in scope and include many individuals and organized methods that go beyond the individual's immediate care. Hence, the definition centrally relates to direct assistance provided in urgent scenarios.
