There are three objectives to first aid: to save life, minimize injuries and hasten healing, as reported by First Aid Regina. There are numerous first aid courses that teach techniques of varying levels of difficulty and complexity to students.
The first objective is to save life. Air is a crucial component required for survival, and one of the first factors that need to be taken into account is whether the airways are blocked. If the airways are blocked, clearing the blockage should be the immediate concern. Without oxygen, brain damage will happen within 4 minutes.
The second objective is to minimize injuries or to prevent them from happening. Survey the area and remove the injured individual away from any objects that may be hazardous. In addition, bandage up all wounds to prevent excessive blood loss. When bandaging up wounds, it is important to remember to apply pressure.
The third objective is to hasten recovery. Depending on what the wound is, there are different treatments that are recommended. For example, for minor burns, cool the burned area by running it under cool running water for a minimum of 10 to 15 minutes. Next, cover the burn with a sterile gauze bandage, and provide the injured individual with over-the-counter pain relievers. Keep an eye out for infections.
