Depth (and potential DCS). You have no idea what depth the boat has sunk to. So let's say it's at 50m, it takes a long time to surface from 50m and if it's already taken you 1 minute to get out of the boat, you're fucked again. Not to mention any DCS you may suffer if you've been breathing compressed air down at 50m for very long!
If the boat is at 50 m the chances of getting rescued in time are probably so low that it may even make sense to try as a last ditch effort? If you remember to breath out on ascent. Hard to say...
- Filligree 2y agoBreathing out isn’t the issue. Sure, you’ll rupture your airways if you don’t, but you’ll still get decompression sickness if you do. So even in the incredibly unlikely scenario that you reach the surface, you’ll have nitrogen bubbles in your bloodstream that’ll quickly kill you. Look up a dive chart; fifty meters is much too far down, especially if you’ve been there a while.
- YZF 2y agoI don't think decompression sickness is the main concern here. Dive boats would usually anchor somewhere relatively shallow. You're probably making some decision reasonably quickly so you haven't absorbed that much nitrogen yet. If you're >50m deep you have other problems (like depth narcosis). Decompression sickness can kill you quickly if you get large bubbles in your brain or heart but that's less typical. Many cases of decompression sickness can be treated in a compression chamber within some reasonable amount of time after surfacing. Onset of decompression sickness is also often delayed by as much as 48 hours.
