How about "mouth to nose" resussitation?
Oh, whoa!!! I've worked in hospitals forever, and in my experience, you sort of get a feeling. You're ready for it. There's back-up.It saved my dogs life. He almost drowned at a hunt test. The photographer taking pictures had just learned mouth to snout. Willy was blue around the mouth and tonge by the time we reached him. The photographer did the mouth to snout while a friend and I did the chest compressions. It seemed like we worked a long time before we got a response. Thanks to quick thinking, some knowledgeable people and a couple of club members who were volunteer firefighter we were able to get him to a vet. The X-ray showed just how much water wae still in his lungs.
