Your diaphram is good for about 1/2 psi or about 1 foot of depth. A snorkel longer than about 1 foot and you couldn't inhale.

I remember reading about this incident...as I recall one of the reasons he was able to survive that long is the CO2 was absorbed by the water so didn't increase to toxic levels.
Vaguely related thread steal: During WWII the submarine USS Tang was sunk by a circular run torpedo. One of the crewmen escaped from the conning tower and paused in an air pocket on the bridge. He spoke with another crew member also there, then made an ascent to the surface---the first recorded occasion of such an escape, IIRC. The other guy didn't. Other seamen used the sub's escape hatch...some survived & some didn't. A total of 9 crewmen survived to be captured by the Japanese they'd been attacking, imprisoned and tortured.
There's a good book about it: Escape From The Deep, by Alex Kershaw.

Uni - Just like fresh snot. I used to harvest the stuff. Only seafood i can't see eating.
Considering drowning is much more concerning than dcs, I would choose to take a quick breath, keep my airway open, and bolt for the surface. A hospital deals with the bends, a coroner with a drowning.

Given that it is at depth, the air is still classed as compressed. Therefore any attempt to make a breath hold ascent would most likely result in lung overexpansion injury and/or DCS, as per usual.
we're with GrumpyOldGuy though, this story sounds more like fiction than fact.

What about hypothermia. Two days submerged in even 80°F water - don't think so.

I just remembered the old Myth Busters episode there they used the pressure difference between the surface and dive depth to literally suck a pig (standing in for a human) into one of the old style brass dive helmets from the dive suit. The entire pig! The result was a gory mix of pulp, blood and tissue worthy of a Friday the 13th movie.
My take away is NEVER EVER UNDERESTIMATE what pressure differences underwater will do to you.
