"Allison MacMath had no medical training. But on a cold morning in February when a man beside her at the dog park suddenly collapsed to the snow she remembered a simple tip When giving CPR skip mouthtomouth and pump to the beat of an aptly named Bee Gees song. As she leaned against his chest she said she sang in her head but out loud at the hook Stayin alive. Stayin alive willing him to hear her. The mans wife comforted him with her own words. Mostly I love you Frank I love you  MacMath remembered Saturday turning to Frank Norris the man whose life she helped save. She said it over and over. She loves you. She really loves you. The two traveled from Langhorne to Penn Medicine in Philadelphia to gather with others who suffered or saved someone from a sudden cardiac arrest. Advertisement They did so to offer support but also to spread awareness because they say too often life and death for someone having a cardiac arrest comes down to chance. If a bystander performs CPR while medics are on their way survival rates more than double doctors say. These guys are all alive today because of luck said Michele Schimers of the Minnesota Sudden Cardiac Arrest Survivors Network who came to Philadelphia to offer advice on starting a network here. We need to take luck out of the equation and give everyone a fair shot at surviving cardiac arrest. Benjamin Abella clinicalresearch director at Penns Center for Resuscitation Science said that means training more people in CPR. The need is especially acute he said in areas with high poverty or large minority populations where research shows CPR knowledge is very low. Everyone knows to call . . . . But most of the time we cant wait said Abella. Usually a cardiacarrest victims fate is sealed in those first five to  minutes. Without intervention cardiac arrest is  percent fatal doctors say. The condition kills about  people each year in the United States  an estimated  in Philadelphia. Joseph Russell of the CPAT Network a group of former and current Philadelphia Fire Department EMTs has been educating Philadelphians about CPR for a decade. In the last year  since a yearold at Andrew Jackson Elementary School died from a cardiac arrest when the school nurse wasnt on duty  the group has trained more than  School District employees in firstresponder skills. We have a long ways to go in the city he said. People tend to wait until the tragic situation happens. So somehow we have to get in the mindset for people to be more proactive and not wait for the disaster."
