A. If the patient is bleeding, try to stop the bleeding first. Don't move the patient. Keep the arm still by using a sling (吊带) and send for an ambulance or a doctor at once. B. Stand behind the person and put your arms around him. Make a fist (拳头) with one hand and make quick and hard movements till the food comes out.
C. If you get hit in the eye with a ball, rock, or something else, put an ice bag on your eye for 15 minutes. Then call somebody to take you to the doctor.
