Document Summary
Heart attack occurs when heart muscle tissue dies because its blood supply is severely reduced or stopped. Cardiac arrest results when the heart stops beating. Chain of survival: five events that must occur rapidly and in an integrated manner during cardiac arrest: recognition and activation of the emergency response system, immediate cpr, aed, ambulance, doctor. Cpr moves blood to the heart and brain by giving chest compressions. Cpr provides periodic breaths to place oxygen into the person"s lungs. Tap the person"s shoulder and ask if he or she is okay. If the person does not respond, he or she is said to be unresponsive. If alone with a child or infant, give cpr for five cycles, and then call 9-1-1. Check breathing for 5 to 10 seconds by looking for the rise and fall of the person"s chest. Perform on a firm, flat surface whenever possible. For an adult: use two hands, compress at least 2 inches.
