How to Do 'Hands-Only CPR' (2/2)
[划词 ]
参考答案: CPR guidelines from two thousand five said only untrained people should use this method. Those with training were told to use traditional CPR. But now the American Heart Association says everyone should use hands-only CPR unless they feel strong about their ability to do rescue breathing.
The organization says the hands-only method was just as effective as traditional CPR in several studies. Scientists say there is enough oxygen remaining in a person's system for several minutes after breathing stops. They also say people need less oxygen when the heart is at rest.
The American Heart Association recommends hands-only CPR for use on adults who suddenly collapse. It says traditional CPR with a combination of breaths and compressions should be used for babies and children. Traditional CPR should also be used for adults who are found already unconscious and not breathing normally. And it should be used for any victims of drowning or collapse from breathing problems.
These are all examples of cases where CPR with mouth-to-mouth breathing may be more helpful that hands-only CPR. The American Heart Association says because there are many such cases, people should still learn CPR that includes mouth-to-mouth.
