Instructor bent after running out of air at 40m

Thanks for the info! When I certify AOW, I'm curious how it will be for me. LOL For some strange reason I "want" to get narced.

Just remember to be observant for it and already have in your mind what to do.

Since AOW is technically maxed out at 100 ft. I'm assuming the narcosis is a lot more manageable than at say 150 ft. Unless of coarse one does not ascend to mitigate the buzz. And instead descends for no apparent reason.

Too happy to realize they are in danger.

Right, I forgot . . .the annoying buzzing sound is another symptom.

A couple of people here had referenced the BSAC reports -- out of curiosity, I looked at the 2017 report. If I read that correctly, it stated that 41% of decompression sickness incidents recorded in 2017 took place within computer or table no-decompression limits. That's a little scary.

Yup - even if you do everything right and follow every rule we have you can still get DCI.
After their 2016 conference and meeting Dr Neal Pollock, I changed quite a few of my behaviors including; almost doubling my deco if I had the gas available, stopping every 1m from 6m to surface, and avoiding over-hydration.

One of the problems with voluntary reporting is only the most severe tend to be submitted. BSAC has tried to estimate the total number of incidents in the past, but they’re just that - estimates.

It really is not as scary as it seems--statistics like this can be deceptive.

I am willing to bet that in recreational diving, nearly 99% of the dives are done within limits. That means that about 60% of the DCS cases come from the 1% that are not within limits. If you start with the fact that the rate of DCS is something like 0.002% of dives, and if you consider that most of that tiny, tiny percentage violated those limits, that makes staying within recreational limits pretty darn safe.

Here is an analogy I have used before. I will bet that well over 90% of the people that die in Germany each year are Germans. That does not mean it much more dangerous to be a German while living in Germany.

That is a great presentation and all divers should take the time to view it. Hopefully the cry to hydrate, hydrate, hydrate will go the way of the quarter turn back and be replaced with "be adequately hydrated"

Forgot on my last post, his presentation also made me lose 50lbs before the next dive season.
I really need to buy him a drink or something.
Please everyone do watch the video, it's 1 hour of good solid information which will make you a safer diver.
