Saving the day: Performing chest compressions correctly

Saving the day: Performing chest compressions correctly: External chest compressions (ECC) can literally be the difference between life or death for someone who has stopped breathing. However new research shows that a person's physical fitness restricts the amount of time they can correctly perform ECC and adds weight to the 2010 European Resuscitation Council Advanced Life Support Guidelines which recommend that that people performing ECC should change every two minutes.
