Sounds a lot like scuba diver's pulmonary edema, hard to breath thinking out of air. I am glad this had a good outcome.
I knew someone would go thereThere are a number of possibilities here from allergies, COPD or even the valve not being open all the way. Based on the limited info of the first aid and treatment I think IPE is unlikely.
Very true....we were taught to ALWAYS 'kill'(stop) your stop watch(ie BT over) and 'dump ' BC air before making your(final) ascent----ALWAYS.....My lil acronym(hey--an acronym before acronyms were cool) was AT--A for air T for time, worked EVERY time even under Heat-of-battle/bun-sweating times---& I still use it today ie I carry & USE a stopwatch on every dive....Bet they're not taught to 'kill' the watch 'these days'....
Stopping the bottom time at the moment of ascent is only necessary when using tables to measure dive times (etc.). It is unnecessary when using a computer.
Dumping air from the BCD prior to ascent works with a properly weighted diver with a thin wet suit. It is absolutely NOT a good idea if you are wearing 7mm or more. With that much neoprene, a diver has no choice but to add a fair amount of air to the BCD in order to compensate for suit compression at depth, and dumping all air at the beginning of an ascent can result in an immediate and rapid descent. Most instructors therefor teach students to dump air a little at a time on ascent, letting out just enough each time to remain a little negatively buoyant so that the ascent can be controlled by swimming rather than BCD expansion.

As I have seen two close friends suffer from SPE (IPE), one of whom died in front of me, I think I have some knowledge of it. Also knowing that the foremost expert in dive medicine (who I know) feels that far more dive accidents/deaths are caused by SPE than previously thought as they are overlooked by coroners/doctors without the necessary knowledge and confused with dronwing.
