Alright, now let’s cover rescue breathing — adult rescue breathing. This is going to be a situation where the scene is safe, your gloves are on, your CPR shield is available. You arrive to find a victim unconscious, at least appearing unconscious. You call out to them. They do not respond to your verbal stimulus. You walk up, the scene is safe again. Tap and shout on the collar bone. They do not respond. You check for a palpable pulse and it’s easily palpable, but they do not appear to be breathing. We activate the emergency medical services or call a code, and if we have a bystander, we tell that bystander “Hey you, go call 911 and come back. I might need your help.” They respond. Now, we know that because this patient has a palpable pulse but is not breathing, they’re going to need rescue breathing. So, we’re going to tilt the head back, lift the chin, seal with the mask. And we’re going to deliver one rescue breath over a second, every 5-6 seconds, for 2 minutes. After 2 minutes, we’re going to assess for a pulse, no more than 10 seconds. If it’s still easily palpable, meaning we can feel it easily, but there’s no breathing on his own, or no appreciable breathing, we’re going to continue rescue breaths, one breath every 5-6 seconds for 2 minutes and keep re-assessing. If, at some point, they lose their pulse, you can’t feel it any more, and they’re still not breathing, that’s when we go into CPR. But, as long as they keep a pulse and are not breathing, we’re going to continue rescue breathing and wait for EMS to arrive or the next advanced life support team to arrive and take over. The scene is safe, my gloves are on. My CPR shield is available. “Sir, can you hear me? Sir? Sir, can you hear me?” There’s no response. “Hey, you in the plaid shirt, would you go call 911? I’ve got a man who’s unresponsive. I might need your help. Please come back.” Checking for a pulse…. Oh, he has a nice strong pulse but he does not seem to be breathing. I’m going to begin rescue breathing. One one thousand, two one thousand, three one thousand, four one thousand. One one thousand, two one thousand, three one thousand, four one thousand. One one thousand, two one thousand, three one thousand, four one thousand. And I’m going to continue this for about 2 minutes. Check for a carotid pulse. If no pulse, if no breathing, start CPR. If there’s still a pulse but no breathing, continue rescue breathing for another 2 minutes and then re-assess.
