How do you give mouth to mouth underwater?

Answer 1

Same as you do above water except it is a lot harder: Tilt the head back or jaw-thrust to establish an airway, take a breath (off your regulator, snorkle, or raise your head out of the water), pinch the victim's nose and blow your breath into the victim watching for the chest to rise. If the chest doesn't rise, re-establish the airway. Don't waste time getting the victim to the surface. If you are ascending from depth, allow the victim's breath to escape so as not to cause the victim's lungs to over-inflate. Try to hold the victim's regulator in his mouth when you are not giving rescue breaths during ascent in case he regains consciousness and begins breathing on his own. Control your ascent so you don't ascend faster than your smallest bubbles (1 ft/second). After you get the victim to the surface, make the victim buoyant by dropping weight or inflating the buoyancy control device. Wave your arms in the air or blow a whistle to signal that you need assistance and tow the victim to shore. If the victim is still not breathing on his own, you should try to deliver at least 4 breaths per minute while you are towing them to shore. A cold water drowning victim is not dead until he is warm and dead. If a victim recovers from drowning, he must still be checked out as soon as possible by a doctor because the water that is absorbed through the lungs can dilute the blood or cause electrolyte imbalance that can kill them hours later. You need to practice the technique under the supervision of a certified Scuba instructor, preferably as part of a rescue diver course and you should take a first aid course. This sort of rescue can be very physically demanding.
