    Agree. A point we all probably know is that keeping your airway open is what counts, regardless of what air is in your lungs. Exhaling only "confirms" that it is open, and saying "Ahhhh…….." only confirms to the instructor during a class that it is open. I do all of the above anyway.

    That was a very rare situation- I don't recall ever hearing about another one. If someone is concerned about going OOA then they might want to practice regular disinfection of the BCD bladder or at least periodically do a REALLY good rinse by removing 2 dump valves and running freshwater through it. (or run water directly into the BCD vent using a garden hose adapter.

    After each dive day I rinse inside the BC with baby shampoo & tons of fresh water (AFTER dumping out as much salt water as humanly possible). I found that this was not discussed very often in OW courses or on SB. I don't know how good this is in preventing infections from breathing BC air--can't hurt.

    Just try to hum on the way up, it will keep your glottis open and any residual air will escape. Just like a cesa with full lungs.

    I sincerely wish the CESA was eliminated from all training agencies that still teach it.........for a multitude of reasons......not least of which the discussion usually brings up the “breathe from your BCD” silliness. Much better off teaching ways to avoid the scenario in the first place.
