he's gonna have some problems. Isn't one of the main reasons divers don't immediately come up because of nitrogen bubbles that could form in the brain if you surface to quickly?

[QUOTE=PLing;26707736]Yes you can. In one episode of mythbusters they tried if cutting pressure from a pressure suit while it was submerged deep crushed the man. It did.[/QUOTE] Here you go. [media]http://www.youtube.com/watch?v=LEY3fN4N3D8[/media] This is why I fear the deep sea.
[QUOTE=yuki;26704086]No need to be so abrasive. Seriously, not to mention it probably gets even more difficult to swim at lower depths AND fuck all cold[/QUOTE] The cold actually helped him slightly due to this thing called the mammalian diving reflex. Wiki: Every animal's diving reflex is triggered specifically by cold water contacting the face[URL="http://en.wikipedia.org/wiki/Mammalian_diving_reflex#cite_note-pmid636078-1"][2][/URL] – water that is warmer than 21 °C (70 °F) does not cause the reflex, and neither does submersion of body parts other than the face Basically when that happens, your body slows your heart rate down then the "lungs filling with blood" (i think) occurs at this same time. More wiki: In biology, the blood shift may refer to a phenomenon seen when mammals submerge in water. It is part of the mammalian diving reflex. Blood vessels in the extremities contract, leaving a higher percentage of the entire blood volume in the torso. An effect important for freedivers is the resulting widening of the lung's capillaries . It reduces the lung's residual volume, thus increasing the depth at which the residual volume is reached (untrained average is at about 30 meters This is why you always here "why can't I hold my breath as long as I can underwater". That reflex has a lot to do with it. But sadly I also read this reflex starts closing off your extremities to conserve blood.. so that definitely wouldn't help his situation.

[QUOTE=SCopE5000;26703872]Shit, lungs fill with blood, that sounds franky terrible.[/QUOTE] That is how you can kill people by penetrating their chest through their lungs. They'll die peacefully when their lungs fill up.

Btw, the previous record holder died doing the same thing. I remember she's only in her 20s. RIP :saddowns:
Uh did they mean that the vessels in the lungs fill up with blood or the lungs themselves :ohdear:

Isn't one of the main reasons divers don't immediately come up because of nitrogen bubbles that could form in the brain if you surface to quickly?[/QUOTE] As mentioned before, it only happens with compressed air from a canister, and Nitrogen bubbles in your bloodstream (known as the bends) aren't that dangerous. The actual nitrogen bubbles won't do anything either. They will only actually be dangerous if the person undergoes pressurization again. It's also easily removable. They put the people in a hyperbaric chamber and just adjust the pressure slowly until the bubbles dissipate.
[QUOTE=PLing;26707736]Yes you can. In one episode of mythbusters they tried if cutting pressure from a pressure suit while it was submerged deep crushed the man. It did.[/QUOTE] That was from a rapid change of pressure, not the gradual change from a diving descent.

How the hell does one hold their breath that long I can only manage one minute
[QUOTE=JWJ;26703626]Oh god.. The thought of drowning and running out of breath would make you rush to the top.. but that would kill you even faster. :aaaaa:[/QUOTE] I thought that only happened when you were breathing out of a tank.
100 meters? How's that even possible?
