Chest compressions preserve brain

Remember the mannequin you awkwardly learned CPR on in middle school? It turns out that the rescue breaths might not have been necessary.  A Japanese study published in the journal Circulation found that the chest compressions given during cardiopulmonary resuscitation (CPR) alone are enough to both revive the person and preserve more brain function.  In fact, those who only received compressions weather the emergency a little better.

Of the 1,376 people studied who experienced some kind of cardiac arrest and received CPR, 46 percent of the survivors who only received chest compressions were still alive one month later.  Only 40 percent of survivors who received both chest compressions and rescue breaths survived another month.  The people who received only compressions were also 40.7 percent more likely to show favorable brain function after the incident compared to only 32.9 percent of people who received compressions and rescue breaths.
