    The most important thing about first aid is to do only what is necessary, but to do that as carefully and quickly as you can. When an accident happens, don’t rush or get excited. Stop and think first. If the injured person is in no immediate danger from fire, water, or traffic, leave him lying where he is. A rolled-up coat or pullover placed under his head, and a coat or blanket over him, is the best treatment you can give while waiting for help. If the person is unconscious, loosen his clothing, especially round the neck. If an arm or leg lies awkwardly and looks out of shape, try not to move it. Remember that you can do a lot of harm by trying to do too much. Of course, there are times when you can’t wait for help and you must do the best you can until a doctor or ambulance arrives. If the injured person has stopped breathing, you must start artificial respiration as soon as possible. If he is bleeding badly, you must act immediately to stop the flow of blood. If you can’t stand the sight of blood, take a few deep breaths through your mouth. This will enable you to think clearly and act calmly.
