Handling Narcosis

[matt_unique]

Ur assumption is correct. But the lack of mind I experience at 140, would it remain the same at 200 or would I not know who my mama is? and at 250 I dont know what MAMA means? U know what I am sayin?

Keep in mind that your experience with narcosis can change from one dive to the next even at the exact same depths and location. Sometimes narcosis results in feeling like you have a buzz, sometimes you may feel immediately anxious with no obvious provocation (dark narc), etc. Your air requirements begin to change DRAMATICALLY with the depths you are talking about. 5 extra minutes at a depth can require 20 minutes additional minutes of decompression for example.

One big thing about deep air diveing is that co2 is very very bad for you and the deeper you go the more you builed up becouse air is hard to breath. Heres a fun fact breathing air at 190 is the same as breathing helium at 1000fsw.
With that point if you have read any books about deep air divers then you know about deep wather black outs from co2 allso co2 is way more narco.

So Training for mixed gas diving and going deep you should have training for and grear if you have ?? about train and grear ask away.

I hope i dont seem to mean but it is unsafe have fun be safe and dive Matt

Thanks a lot. I am in no mood to dive below 130 without proper training / preparation. I was told by someone on this board that mixed gasses do nothing to eliminate narcossis and you just have to develop "tolerance" for it. After experiencing narcossis myself I thought how would that be possible? How would you develop "tolerence" towards something that is meant to happen at that depth? It was that idea that started the post.

Wow:11: It would be wise to disregard everything that person has ever said.

LOL that is the stupidest thing i have ever herd He must of been thinking of nitrox witch was a misconception at one point but helium based gases are still narcotic but no were near the nitrogen based gases you will never see the difference till you try helium . First dive i did on trimix was on a wreck i have dove 50 times before and i noticed stuff i have never seen its kinda of a trip . I try to keep my narcotic depth around 80-100 ft and have a po2 of 1.2-1.3 working i have done deep dives on air in the 165 range trust me its a pile of work to stay sane i get really nervous when narced

That's sheer foolishness, substituting Helium for Nitrogen has been shown to control narcosis. How much control and the depth at which it is needed is open to discussion, but each and every diver will need it at some depth.

They seem to be of the opinion that 'acclimatization' is little more than your ability to know what to expect.

"acclimatization" is probably dominated by staying calm and relaxed and not building up any CO2. recent diving experience at whatever your target depth is will help build confidence and keep you relaxed which keeps the CO2 low which keeps your head clear -- at least until it all goes sideways and you take a CO2 hit...

SB is full of 'toilet bowl' divers handing out all sorts of crap......

The cult of the the amateur strikes again.

After 15 dives on the same wreck in Vanuatu i had worked my way down thru all the ship except to the stern. When i dived the stern(non-penetration) i got down to a max of 64m and was fine to start with(~220ish feet i think) tho after a few mins i felt like i was on strong drugs(strong extacy mixed with NOS for anyone in the know), i can say it was truly spiny as. It was kind of a mental struggle in your brain to keep it focused on what your original plan was rather than swimming off after some brightly colored fish who just talked to you. That and i was getting interesting sound effects that are hard to explain.

After a couple of mins down around the 60m mark we raised to 55m to use up the other 10 mins bottom time(haha we were doing laps of the swimming pool so we were probably still a bit narked) tho i felt so much more sober than down that bit deeper. I was diving in a 3mm shorty in 26oC water with 50m vis and no current.
