AHA - Hands Only CPR
When an adult has a sudden cardiac arrest, his or her survival depends greatly on immediately getting CPR from someone nearby. Unfortunately, less than 1/3 of those people who experience a cardiac arrest at home, work or in a public location get that help. Most bystanders are worried that they might do something wrong or make things worse. That’s why the AHA has simplified things.
