Without it, many people are too afraid to attempt CPR as they could cause more damage to someone in need. 100 BPM Simplified Chest Compression increases the success rate of administering CPR to an adult after cardiac arrest by giving feedback to the rescuer through sound and light to ensure the CPR is done properly. 100 BPM guides the rescuer by simplified resuscitation procedure involving only chest compression, with no mouth breaths action.
