What the method of CPR?

C: Compressions

* Place the heel of one hand on the center of the person's chest, between the nipples.

* Place your other hand over your first hand, interlacing your fingers.

* Give 30 chest compressions at a rate of 100 to 120 per minute.

* Push down 3.8 to 5 cm (1.5 to 2 inches) on the chest.

* Allow the chest to recoil between compressions.

P: Protective Airway

* Tilt the person's head back to open the airway.

* Pinch the person's nose shut.

* Give two rescue breaths, each lasting about one second.

R: Rescuing breaths

* Watch for the person's chest to rise and fall with each breath.

* If the chest does not rise, reposition the person's head and give another rescue breath.

Continue CPR until:

* The person starts breathing,

* A defibrillator is available, or

* Emergency medical help arrives.
