At the weekend, some of our club headed over to the Hyperperbaric Treatment and Training Centre over on the Wirral for a 40m ‘pot’ dive (which is a dry dive where you get to experience serious nitrogen narcosis in a safe environment)
Starting with a very informative talk from the Centre Operator Dave Adcock on the science behind, and the difficulties in, treating DCI (Decompression Illness), this was followed by a facilities tour by Jen, the centre’s Operations Manager. It’s an amazing medical facility able to cope with any and all situations.
After the tour, it was into the pot!
Once in, we descended to 40m and then the merriment began as everyone sounded like they were breathing helium at these depths - due to the thicker gas. Funny enough at the best of times, but with the narcotic effect making everyone feel like they were drunk, it was hilarious!!
After a minute, at the bottom (40 metres) we started the test we were given to do. This is where things get serious as you realise just how impaired your cognitive abilities are when you get ‘nitrogen narcosis’ (aka ‘narked’ or ‘raptures of the deep’).
Simple things become difficult - if not impossible - to do…. a dangerous situation underwater should quick thinking be required.
It certainly highlights the need to be breathing the best gases possible to combat the effects of nitrogen in our air when diving at depth.
But we all returned to the ‘surface’ safely after a few decompression stops, and followed the fab experience with a bite to eat in a local pub before heading back over the Pennines.
A top day and a great experience!
