Capt. Shawn Tulp: Say, like, you find an adult who's down on the ground. How long should you wait before you call for help? You come by, you notice he's unconscious.
Student 1: Right away.
Capt. Shawn Tulp: That's right, call right away. So you're going to look, listen and feel. You're going to listen very — listen for your air. You're going to watch for the rise and fall of the chest. If I don't hear anything, I'm going to deliver two breaths. Once you establish that there's no pulse, that's when we begin our 30-to-two compressions. So when you start CPR, you're going to count up one and two and three and four and five. How long do you think you can last doing this?
Student 2: A couple minutes.
Capt. Shawn Tulp: Yeah, it'll wear you out. It will definitely wear you out. All right, so on top of CPR we also have another something that helps us out a lot. We have an automated external defibrillator, an AED. Now the function of the AED is to do one thing and one thing only, and that is to defibrillate lethal rhythms. When you turn it on your AED, and I wish this one would work, it'll tell you exactly the steps to do. First thing it'll tell you is say, "apply the pads." Then you'll plug in your machine. It'll say, "analyzing rhythm." It takes about five to 10 seconds. At that point you have a little button you press. Now, before you press that button, be nice to everybody that's around you. Tell them to clear the patient. Then we press the shock button. They will jump. It's hard to mess up, and it's designed for the lay rescuer. Any questions?
