It is important for you to learn some knowledge about first aid in your daily life.If a person has an accident，he needs medical care before a doctor can be found.When you give first aid，you must pay attention to three things.First，when a person stops breathing，open his/her mouth and see if there is food at the bulk of his/her mouth.Second，if a person cannot breathe，do your best to start his/her breathing at once，using a mouth­to­mouth way.Third，if a person was hurt badly，try at once to stop the bleeding.Then take him/her to a doctor.If a person loses one third of his/her blood，he/she may die.

First aid is defined as the emergency care given to a sick or injured person.The goals of first aid are to prevent death and to prevent injuries from becoming worse.Each emergency condition is different.However，the following rules apply to any kind of emergency.

*Be aware of your limitations.Do not try to do more than you are able to. Nor should you do things if you are unfamiliar with them. Do what you can under the conditions at the time.

*Stay calm.Acting calmly will help the victim feel safe.

*Take a quick look to see if the victim is bleeding，and if there is a pulse.

*Keep the victim lying down and do not move him/her.You could make an injury worse if you move the victim.

*Call for help or ask someone to make the EMS system (急救系统) start.

*Keep the victim warm.Cover the victim with a blanket. Coats and sweaters can be used if a blanket can not be found.

*Reassure (使……安心) the victim. Explain what is happening and that help has been called.

*Do not give the victim any food or fruit.

*Keep the bystanders (旁观者) away from the victim. Bystanders want to have a look，offer advice，and say something about the victim's condition.The victim may believe that the condition is worse than it really is.
