1.) Verify that the scene is safe for the rescuers and the victim.
2.) Check for responsiveness. Tap the victim's shoulder and shout, "Are you OK?"
3.) If the victim is not responsive:
The first rescuer assesses the victim and, if no mobile phone is available, sends the second rescuer to activate the emergency response system and retrieve the AED and emergency equipment.
4.) While the second rescuer is activating the emergency response system and locating the AED and emergency equipment, the first rescuer checks the victim for breathing and a pulse. This is done simultaneously and should not take more than ten seconds.
5.) If the victim is not breathing normally or is only gasping and has no pulse, immediately do the following:
~One rescuer begins high-quality CPR, starting with chest compressions. Remove or move the clothing covering the victim's chest so that you can locate the appropriate hand placements for compressions. This will also allow placement of AED pads when the AED arrives.
~ Once the second rescuer returns and 2- rescuer CPR is provided, rescuers should switch compressors frequently (about every 2 minutes or 5 cycles, typically when the AED is analyzing the rhythm) so that the CPR quality is not reduced because of fatigue.
6.) Use the AED as soon as it becomes available and follow the prompts.
7.) After shock delivery or if no shock is advised, immediately resume high-quality CPR, starting with chest compressions. Continue to provide CPR and follow the AED prompts until advanced life support providers take over or the victim starts to breathe, move, or otherwise react.
