Explain the full process of CPR
What is check for alertness, if no response, shout for help--get someone to call 911, place person on his/her back, perform chest compressions keeping a chin lift, give 30 chest compressions, open airway, check for breathing. If not breathing, give two rescue breaths and resume chest compressions--30 compressions followed by 2 breaths. (Note: The rescue breath portion of CPR is changing)
