CPR Should Only Be a Hands-On Approach 

Photo Courtesy - Getty Images(ARIZONA) -- A new study in the Journal of the American Medical Association shows that mouth-to-mouth breathing might not be necessary in resuscitating someone who has suffered a heart attack.

A team of Arizona physicians says performing CPR would likely be more effective by just delivering chest compressions in the case of a cardiac arrest patient.

This finding fits in with previous research of “hands only” cardiopulmonary resuscitation performed by bystanders with no first aid training.

Conventional CPR involves chest compressions and mouth-to-mouth breathing intended to deliver oxygen to a patient’s lungs.

After the Arizona doctors observed cases of people receiving hands-only CPR and those receiving conventional CPR, the survival rate turned out to be greater when just chest compressions were used.

As expected, the survival rate was lowest when people performed no CPR on patients.
