ok, a bit clickbait like title - but lets discuss the idea behind that dive :-)

All well done. I am happy to be an ISE diver by heart. Great Video from the guy who had the pleasure to shake hands with Richard Pyle.

I agree with your deco philosophy. Shallow deco stops are the way to go. Get above the “deco zone” soon as possible. Thx for sharing.

Exactly. Fast tissue and slow tissue compartments. Get out of the deep and protect slow tissues from super-saturation and cut down on hours of unnecessary deco. Slightly worrying how much resistance there still is to moving on from deep stop 'theory'. The best explanation I've ever heard from a deep-stopper is 'this is what someone told me when I started diving and I'm too scared to change'

I recently did a Deco for Divers course with Mark Powell and he does a great job showing the current research on deco and showing why deep stops are no longer recommended. I enjoyed going beyond the never-ending internet discussion and looking at the data.

Hey, Just typed all the numbers into subsurface to visualize the profile. Actually subsurface came up with similar profile and length. With slightly longer stop at the end, but same idea. Which is not surprise. However! I had ether allow last stop to be at 3m or disable oxygen brakes, and if I do i can see, you probably have exceeded your CNS clock, by a lot. CNS: 128% That was definitely a risk factor. I know that is highly personal metric and probably a topic for another video.

Not yet at those depths, Achim... But it makes total sense

Shows how far we've come from Pyle stops and the VPM profiles. I know some people who swear by VPM and it works for them, but for me I've been great with profiles like this one. I personally use Buhlmann algos with 60/85 gradient factors, though I know of folks who do 99/99. Ultimately deco is still more art than science and is very dependent on individual physiology and personal and environmental conditions on the day of the dive (hydration, temp, etc.). I'm really looking forward to advancements in theory and wearable monitors that can provide better feedback on what's happening internally to tune algorithms and stops on a dive-by-dive basis.

I'd like to have an ultrasound transducer incorporated into a chest band or similar to monitor microbubble evolution during deco.

@tonfleuren3536 Жыл бұрын

@@GwynRosaire Yes, it would be great to get real-time monitoring, to really see what is happening. I'd think the deco is most effective at the point where you a small amount of microbubbles. Deco profiles are based on physiology of "average" divers (at some point, very fit military divers), and it would be good to know how it works for you personally. Age, general fitness level, etc. will have a significant influence, and I wouldn't be surprised if there is also a difference between men and women, considering women generally have a higher body fat ratio, among other physiological differences. Remember heart attacks also manifest very different in women, I see no reason to assume men and women are exactly the same when it comes to decompression.

@tonfleuren3536 I agree with both of you. I'm a bit flabby, mostly out of shape guy (working on it) and I really don't compare well to the PT studs that most of these tables are derived from.

"I reached 120 meters in 3 minutes" I'm not sure why but that made me laugh. Very well said.

Makes sense. We use half max depth to start our stops.

would you be interested in doing a video on flying after diving and are there ways to lower time between dive and flight say with higher O2 ?

No HPNS symptoms? That's a ton of helium at a high pressure. I would've thought of getting some nitrogen in the bottom mix.

Pyle stops and the bubble theory, what a mess. Deep stops, ichthyology, pretty crazy how one guy could cause the US Navy to do a study on how much better Mr. Pyle felt after stoping deep so he doesn't kill his fish. Just goes to show how much of deep technical diving is theory. Stay safe.
