The DM (presumably that's what he was) may well have prevented an overexpansion injury. The student in this case may well have felt supported, comfortable, and all warm and fuzzy topside if allowed to punch out. That nice, supportive, comfortable feeling a surprising majority of people here seem to think is so important would have done nothing to keep an AGE at bay. Gas in your closed lungs cares not whether you are in a pool, a lake, or the ocean. It cares not what depth you are at -- except that it will expand faster on a 5 foot ascent from 5 to zero that from 35 to 30.
That's right, all the warm and fuzzy in the world will not change physics. The closer you are to the surface the faster the bubble grows (and quicker it gets into the blood) for the same relative ascent distance. In that sense a pool can be a dangerous place for beginners on scuba.
As has been pointed out, you can cough, puke, yell, spit, anything else through the reg. Being on the surface won't get you not coughing quicker if you keep the reg in your mouth, but bolting for the surface in panic can get you a stroke pretty quick, and I do know a diver who stroked out due to an AGE from a less than 10 foot ascent, and that ascent was deeper than any pool.
I'm sure the DM here has a side to the story. I'm sure it was seeing a breath holding diver bolt.
Come on, maybe the guy is bad with names. I am. Give him a break. He may have saved her life.
And regs don't come in "sizes" unless you buy a custom mouthpiece. Until you buy your own gear your going to have to learn to live with imperfect stuff, and even then things break.
