"The revised guidelines issued Monday by the American Heart Association on cardiopulmonary resuscitation advise giving 30 chest compressions -- instead of 15 -- for every two rescue breaths.

The guidelines also recommend that emergency personnel cool cardiac arrest patients for 12 to 24 hours to about 90 degrees Fahrenheit. Two significant studies have shown that such cooling results in improved survival and brain function for those who are comatose after initial resuscitation." (CNN)
