This is a great talk. Thank you Mark and Thank you Dive Spear and Sport. I believe this is the second time I've listened to this webinar, and probably won't be the last time.
This was hugely educational. Thank you so much for sharing it! This has given me a much greater appreciation for what's going on inside my computers' models.
I am an engineer and a tek beginner. I understand you 💯%. All those over confient Divers trying to explain me failed miserably. Thank you Sir. We feel the passion.
thank you for the upload. great talk/class. hypothetical question: if blood is whats caring gas into the tissues, blood transfusion/dialisis or some of the sorts could help with serious cases of DCS?
Given the bubbles are being produced by the tissues then carried by the blood, you would need to have the venous blood on a complete bypass. Sounds much more dangerous and complicated than recompression.
I don't understand why the M Value blue line is not parallel to the green Ambient Pressure Line. As with the example of a tissue with a 2 bar limit for the M value, there should be a constant difference between the blue and green lines, which implies parallelism. If not, as it is shown, it implies that the M value can increase with depth. Can you explain? Regards.
Good question! Perhaps his graph isn't quite accurate, or perhaps the relationship between the ambient pressure and M value isn't strictly proportional. His graph shows at 10m the "margin" between ambient and M value is lower. Perhaps at 100m that allowable difference (as an absolute value in psi or bar) is greater therefore the lines diverge. Further digging required.
Good subject and with lots of potential. But certainly the presenter misses some fundamental definitions from a thermodynamics, and physics stand point. Saturation vs. Supersaturation definitions are very, very weird. Where do you come with those definitions from. This is all physical-chemestry dynamics. Nothing exuberant. Very straight forward. You are talking about gas solubility in solutions or tissues at contant temperature (body temperature) and while pressure variation. There are more easy ways to explain this principle. You are all over the place with it. In fact, your visuals are kind of confusing As I said, there is tremendous potential for this subject. Thank you anyway.
Amazing presentation. Now i finally understand the purpose of the 16 tissues in ZH-L16! Thank you very much 😊
This is a great talk. Thank you Mark and Thank you Dive Spear and Sport. I believe this is the second time I've listened to this webinar, and probably won't be the last time.
Finally someone made it make sense to me. I've read so many articles and watched videos etc... Very good job at painting the big picture!

Great explanation thank you. Seen Mark at the UK shows several times and have the book. Always interesting.
Thank you very much, really informative.
Thank you a lot for the excelent explanation, it helped a lot in understanding the logic behind deep stop.
Thank you for posting this video. This video cleared up a few things for me. Safe diving mi amigos.
Excellent tutorial Drº Powell, already read your "deco for divers "book and really helped understanding Deco theory. Thank you very much.
This is so interesting and informative. Thank you!!!

Great webinar, made decompression look easy.
Great webinar, but made deco look like blind shooting to me
Really enjoyed this.

Very educational for me! One question: with ‘standard’ GF’s were are more conservative at depth. Why? Why not use 70/70 for instance?
Thank you!

It's too rigid, not enough flexibility to serve a wide enough range for different body types and fitness levels.
Helpful video
24:41 Critical supersaturation.
I use a Shearwater GF 40/85
I'd like a signed copy
The first graph is actually a logarithmic function.

You should produce a video to correct his errors .
How many books have you written on decompression theory?
