Some medical types released a study on CPR, that found the benefit of chest compressions alone, can be just as beneficial as the current procedure for CPR with mouth-to-mouth ventilation. They also studied the reactions of people when confronted with someone who’s collapsed, and discovered 70% of bystanders do nothing, partly because they’re afraid of touching a stranger’s lips.

But the information shows when someone collapses it’s often due to a heart attack, where the blood is properly oxygenated, and circulation is the real key. The new recommendation is for one hundred chest compressions a minute, which doesn’t leave much time for anything else. Of course, mouth-to-mouth is still vital for drowning victims, and it wouldn't hurt to take a refresher class from the Red Cross.
