. O" r) H; s9 D1 }MONDAY, March 31 (HealthDay News) -- If you see someone collapse ina public place or at home and you think it might be a heart attack,start pushing on his or her chest as hard as you can and as often asyou can.
Those are the latest instructions from the AmericanHeart Association, which asserts that hands-only cardiopulmonaryresuscitation (CPR) can be done in an emergency situation, even bypeople who have no training in the technique.
1 N+ j9 |0 c' T; }- t+ XThe statement, published in the April 29 issue of Circulation,does not rule out mouth-to-mouth breathing as part of CPR. "But we havelearned enough to say that passers-by can save lives with chestcompression alone," said Dr. Michael Sayre, an associate professor ofemergency medicine at Ohio State University and chairman of the AHAcommittee that wrote the statement.
"We believe thatapproximately 250,000 Americans suffer cardiac arrest each year," Sayresaid. "Perhaps 15,000 of them will live. We believe that getting morepeople to do CPR could probably save thousands of lives a year."
1 n0 |1 W) t& M3 _6 jThedetails of traditional CPR -- how often and how hard to push -- can beignored, Sayre said. "We've done a little bit of research to suggestthat most people are not likely to push hard enough and it's difficultto push too hard or too fast," he said.

OThe newrecommendation for hands-only CPR is an update to 2005 American HeartAssociation guidelines, which said bystanders should usecompression-only CPR if they were unwilling or unable to providebreaths. Three studies published in 2007 showed no negative impact onsurvival when mouth-to-mouth ventilation was eliminated, theassociation statement said.
