Burn patients typically don’t go that “deep” in a HBO chamber for wound treatment. I don’t have the wound treatment tables in front of me, but I THINK it’s only down to 20’-ish. Plus, with unconscious patients you also have the option of an elective myringectomy (perforating the ear drum).
I’m COMPLETELY speculating here, but it would seem that you’d want the “victim” diver to at least be conscious enough to manage their airway, cooperate with instructions and let you know if there are any problems. Unconscious with a leaky or dislodged AGA isn’t a great recipe for success. Again- just offering it up for discussion- I’m not a cave diver.
