Immersion pulmonary oedema explained
The hidden killer: Immersion pulmonary oedema (IPO)
On ease of breathing, 18:30 is illustrative, though in the context of IPO for the inhale phase.
IPO is eye opening, to me, and a compelling reason to me to dive horizontal, particularly given all the other good reasons to do so. I'm NOT saying this is the driving reason why a short ascent phase should be done horizontal, I think depth control is that reason and that ascending horizontal is no different than adjusting depth the rest of the dive.
On gaining back on exhale the extra effort that inhale took, that has not been my experience floating in a pool in skin gear, no snorkel, watching students on the surface, vertical vs horizontal.
