Make sure that the area is safe

First gesture: Clear or survey the area.

1. Attempt to wake victim. If the victim is not breathing (or is just gasping for breath), call emergency services number of your country immediately and go to step2. If someone else is there to help, one of you call EMS while the other moves on to step2.

   If the victim is breathing, there's no need for CPR.

2. Begin chest compressions. If the victim is not breathing, place the heel of your hand in the middle of his chest. Put your other hand on top of the first with your fingers interlaced. Compress the chest at least2 inches (4-5 cm). Allow the chest to completely recoil before the next compression. Compress the chest at a rate of at least100 pushes per minute. Perform30 compressions at this rate (should take you about18 seconds).

   If you are not trained in CPR, continue to do chest compressions until help arrives or the victim wakes up.

   It's normal to feel pops and snaps when you first begin chest compressions - DON'T STOP! You're not going to make the victim worse.

3. Begin rescue breathing. If you have been trained in CPR, after30 compressions, open the victim's airway using the head-tilt, chin-lift method. Pinch the victim's nose and make a seal over the victim's mouth with yours. Use a CPR mask if available. Give the victim a breath big enough to make the chest rise. Let the chest fall, then repeat the rescue breath once more. If the chest doesn't rise on the first breath, reposition the head and try again. Whether it works on the second try or not, go to step4. If you don't feel comfortable with this step, just continue to do chest compressions at a rate of at least100/minute.
4. Repeat chest compressions. Do30 more chest compressions just like you did the first time.
5. Repeat rescue breaths. Give2 more breaths just like you did in step3 (unless you're skipping the rescue breaths).
6. Keep going. Repeat steps4 and5 for about two minutes (about5 cycles of30 compressions and2 rescue breaths).

   If you have access to an automated external defibrillator (AED), continue to do CPR until you can attach it to the victim and turn it on. If you saw the victim collapse, put the AED on right away. If not, attach it after approximately one minute of CPR (chest compressions and rescue breaths).

7. After2 minutes of chest compressions and rescue breaths, stop compressions and recheck victim for breathing. If the victim is still not breathing, continue CPR starting with chest compressions.
8. Repeat the process, checking for breathing every2 minutes (5 cycles or so), until help arrives. or the victim wakes up.
