Okay, so, I'm about to tell the scariest thing that ever happened to me. The thing is, I'm not an english-speaker, and even though I manage, I'm not sure about all the technical scuba diving vocabulary. I'll do my best but please be indulgent !
It happened last year between Christmas and New Year's Eve (I'm from the French Carribean so it's not unusual to scuba dive during christmas holidays). My family and I (25f) booked a few dives. They're all really good scuba divers, better than me. They passed a few scuba diving levels that allow them to participate in way more technical dives that I'm allowed to do. I enjoy scuba diving as well and I'm able to do almost every "casual" dives but I don't feel safe diving without an instructor yet (even more if it's a dive with decompression stops required).
If anyone isn't familiar with scuba diving, here's a quick explaination : you can dive safely until a certain deep before the pressure becomes dangerous. If you dive below that point (which is roughly 20 meters or 65 ft) you have to do decompression stops during your ascent. It means that you have to stop while going back to the surface a certain time to let your body adapt itself to the pressure. If you ride up too quickly you may catch decompression sickness which can lead, in worst case scenario, to death.
So, we decided that I could manage a little private lesson with an instructor first, prior to more exiting dives with my family. So, the first day, my family was enjoying a dive on a technical spot that I wasn't feeling up to while I was alone with my instructor and retrieving my old scuba diving reflexes. Everything went okay. We were on a beautiful coral reef, there was many begginers on the boat and I was by far the more experiented here. So finally my instructor deciding that he could manage me with another student (which was truly a begginer) and after a small briefing with every safety rules and hand sign (which is the only way to communicate underwater), we begun our descent.
I quickly retrieved all my old reflexes and was enjoying myself, going back and forth to the instructor and the begginer driver, during at least twenty minutes. Everything was perfect beside one thing : it was a windy day and there was an heavy swell. It's less of a problem underwater that it is for "surface swimmer", the only thing was that it requires more physical effort to swim and so my air bottle was emptying a little quicker than usual, which is normal.

I understand that breathable air behaves differently underwater due to higher ambient pressure, and that for some reason it causes bubbles in your blood vessels if you ascend too quickly. But I couldn't understand why that is.
Additionally, given the same supply of air tank, why is it the case that if you are living in a underwater habitat, then you can dive for longer hours as opposed to someone who came down from the surface?
Hey Baro reddit.
Probably a silly question, I play multiplayer with some friends who are newish and often we find ourselves in the situation where someone has either been injured and now unconscious underwater, or they have accidentally let their o2 run out and have then passed out from lack of oxygen and are now floating there dieing.
I successfully grab them and replace their o2 with a full tank, but this does not bring them back to life.
When this happens and it's dry, I just take the suit off and do cpr and it normally saves them.
However when the entire ship is flooded and they have to remain in their suits..is there a way to save them? Does CPR work when they are still in their diving suit with a full oxygen in it? Or does it have to be dry to save them?
Thank you for the read!
I'd prefer a book that focusing on the world-building aspect of it as much as the characters, if not more,, and not just use the world as a shallow plot device to get from point A to B. I've never read any books with this kind of world-setting and I'm in mood to read one.
Thank you.
