This can make some people nervous,but in most cases,they are not serious. Most people will experience it in their lifetime. How to deal with it? Have the person sit up and put the head down a little. Tell the person to press the sides of his nose for 10—15 minutes until the bleeding stops. Don't move the head backward because the blood may run into the mouth or even lungs(肺).

Being choked
This may happen to people who eat too fast. If this happens,stand behind the person and then put arms around him. Put one fist(拳头) on the person's stomach and place the other hand on the fist. Press the person's stomach with both hands continuously until the thing comes out from the throat and the person can breathe again. If you do it for five times but the thing still doesn't come out,call 120.

Burn
