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?
@Flyingjaffacake 4 сағат бұрын
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.

Amazing presentation. Now i finally understand the purpose of the 16 tissues in ZH-L16! Thank you very much 😊

when I took my into to diving NAUI course (Lee Somers 1973) NEVER were we told to dive alone. The buddy diving mantra was pounded into us, as was 1 reg buddy breathing. It wasn't until I looked into tech diving that the "you are your own buddy" concept was introduced to me. I've been diving for a long time and perhaps things/concepts have changed, however, in my opinion adventures are always better when shared with a friend/buddy. AND, when SH_T happens, and it will, it is always good to have some help.

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.
@Flyingjaffacake 4 сағат бұрын
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.

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! Serge

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.

Also sure that NAUI has always stated that ALL certified NAUI divers are fully qualified to dive solo because they are trained as 100% self-sufficient divers from day one. There’s a reason NAUI does NOT have a “solo diver” course. Because if you’re qualified to dive, you’re qualified to dive solo already.

Wasn’t NAUI the first agency to embrace and teach Nitrox? 🤔
@Sidemount_Ben 7 ай бұрын
late reply, I just saw this, but Actually no, In the beginning, ANDI and IAND (new nitrox-specific training agencies) were the only ones who taught its use. Starting with IAND that is now IANTD, It started with Dick Rutkowski, the former dive supervisor for the National Oceanic and Atmospheric Administration (NOAA), formed the International Association of Nitrox Divers (IAND) in 1985 to teach nitrox to recreational divers. This program was developed through NOAA during his tenure. American Nitrox Divers International (or ANDI) was founded by Ed Betts and Dick Rutkowski in 1988 and they ended operations in 2000. NAUI refers to themself as the first commercialized recreational organization to teach nitrox, yet that is a misnomer.

Was this an actual try dive in a drysuit? As this is what I would love to be able to do a try dive while wearing a drysuit with a qualified instructor in a swimming pool and have pictures of me in drysuit on the side of the pool entering the water under water exiting the water and back on the side of the pool
