CPR is an effective form of first aid (give) to the victim whose heart suddenly stops.
Doing it can increase the chance of the victim's (survive). So knowing CPR can be a real lifesaver.
How to give CPR? There are (simple) three steps. Firstly, roll the victim over onto his back and do the chest compression(按压). this way, it keeps blood flowing to the brain, heart and other organs. To perform the compression, place one hand over other and press firmly on the victim's chest many times in a row, (push) at least 2 inches deep on every compression. Then after the compression (complete), check the airway (see) whether the person is breathing. If not, perform mouth-to-mouth, helps to deliver oxygen to the victim's lungs. And the chest compression should start again right after two breaths are given.
Learn CPR, for you never know when you might need . And it feels good to know that you could help in an emergency.
