Never took a class? No problem. Scientists say even incorrect chest compressions can be a life-saver
So you havent gotten around to donating blood or getting on the bone marrow transplant list or taking a class on CPR. Its time to step up, people. Fortunately for you, you can cross the last one off the list, sort of. The American Heart Association is letting everybody know that even if you arent trained in CPR, jumping in and administering chest compressions if you witness an adult collapse after having a heart attack is more than twice as likely to save his life than just calling 911 alone.
