Hyperbaric chambers are known as "pots" by divers, after one of the most famous; the chamber designed by Jack Haldane, son of JS Haldane who, among his many other accomplishments, pretty much single-handedly created dive tables and made it possible to dive without giving yourself the bends. More about the amazing Haldanes here: Grace under pressure.
The next training course will be in two week's time, and will involve no diving at all; I'm renewing my Emergency First Responder certification. Basically a First Aid course angled at divers. I last did this two years ago, and I'm overdue a refresher. My memories of the last time I did this mostly go as follows:
- One of the senior divers there had a small white Scottie dog that used to live in the shop. One look at all of us crowding in to do our training, and it ran and hid under the wetsuit rack, and wouldn't come out.
- Most First Aid training is less about splinting broken bones and more about "here's how to keep them alive until the ambulance gets here".
- The instructor [who works as a nurse] started the CPR training by remarking "I've done this for real three times; they all died". (Statistically, that's pretty much how it goes. the odds are one in ten, but you do it in the hope that the person you're currently rescue-snogging will be the one in ten.)
