This Introductory video clip helps you to determine the need for CPR under the guidelines of the American Heart Association. Before you give CPR, you will check a response level by tapping and shouting. If they are not responsive, you want to make sure to activate the emergency response system, namely by having someone call 911 and get the AED. You will also check for breathing. If they are not breathing, or only gasping, then you’ll know that you have to start CPR. Being trained and certified in CPR can really help save a life!
