I have always worried, if the need arose would I be able to to perform CPR. With the combination of breaths and chest compressions, I was almost certain I would be of no help. However, I recently read about the new method of Hands-Only CPR in which you only give the chest compressions -- 100 rapid hard compressions per minute. No breaths necessary.
The article recommended this video that could help you (and me) save a life. After watching it, it is far more likely we will take action if we witness someone in cardiac arrest; and we'll be more effective, too.
