First aid is the initial care provided to an injured or ill person by a non-expert until definitive medical treatment can be accessed. It involves treating issues like nosebleeds, objects in the eyes, burns, and sprains in a gentle, observant, and resourceful manner without causing further pain or alarm. Proper first aid aims to soothe the victim while making the best use of available materials, with an understanding attitude and a willingness to keep learning improved techniques.
