well, you could have a pony tank in the cave, so itll give you more time to accend i guess. besides, why is blowing bubbles so dangerous anyway, if the pressure inside your lungs gets to high the bubbles will come out faster themselves, so it doesnt sound that bad. and how much could something like hat possibly cost? also depends what gas is in the cave, something like nitrox wont be as bad if you go up fast.
