...the appropriate method. "This study confirms how critically dependent the outcome of out-of-hospital cardiac arrest is on the willingness of bystanders to activate emergency medical services and promptly initiate continuous chest compressions in a case of witnessed unexpected collapse in an adult," Ewy says. ...ACS News Service Weekly PressPac -- March. 14, 2007
