Chest presses, not breaths, help CPR

In a different life I spent a number of years teaching CPR and First AID .

Chest compression — not mouth-to-mouth resuscitation — seems to be the key in helping someone recover from cardiac arrest, according to new research that further bolsters advice from heart experts.

A study in Japan showed that people were more likely to recover without brain damage if rescuers focused on chest compressions rather than rescue breaths, and some experts advised dropping the mouth-to-mouth part of CPR altogether. The study was published in Friday’s issue of the medical journal The Lancet.

More than a year ago, the
American Heart Association revised CPR guidelines to put more emphasis on chest presses, urging 30 instead of 15 for every two breaths given. Stopping chest compressions to blow air into the lungs of someone who is unresponsive detracts from the more important task of keeping blood moving to provide oxygen and nourishment to the brain and heart.

Another big advantage to dropping the rescue breaths: It could make bystanders more willing to provide CPR in the first place. Many are unwilling to do the mouth-to-mouth part and become flummoxed and fearful of getting the ratio right in an emergency.

Sudden cardiac arrest — when the heart suddenly stops beating — can occur after a heart attack or as a result of electrocution or near-drowning. It’s most often caused by an abnormal heart rhythm. The person experiencing it collapses, is unresponsive to gentle shaking and stops normal breathing.

In the new study, researchers led by Dr Ken Nagao of Surugadai Nihon University Hospital in Tokyo analyzed 4,068 adult patients who had cardiac arrest witnessed by bystanders. Of those, 439 received chest compressions only from bystanders, and 712 received conventional CPR — compressions and breaths.

Any CPR attempt improved survival odds. However, 22 percent of those who received just chest compressions survived with good neurological function compared with only 10 percent of those who received combination CPR.

    Did you know that sometimes people vomit during a heart attack.

  2. Fine, but if George Clooney has a heart attack anywhere near me, I am so doing the mouth to mouth.
