First aid is the simple quick help given to a hurt person before the doctor comes. A first aid kit, do a first aid course, give first aid.
The aim is to keep somebody alive and stop things getting worse rather than to treat them properly. Every workplace of any size is required to have somebody trained in first aid on the premises.
