Apnea Diet

They reckon that when the body is starved of Oxygen, it turns sodium nitrite into nitric oxide, which dilates vessels and allows more oxygen-carrying blood through. ( That bit didn't quite make sense to me, as I've always understood that the blood-shift involves the opposite - vasoconstriction to the extremeties, to retain blood within the core. ) Anyway, this was one of those short newspaper articles, not a medical journal paper. Might be worth looking into, though.

Fascinating!
Sad that Sodiun nitrite is also suspected as a carcinogen, especially of the colon IIRC.
The confusion between vasoconstriction and vasodilation in that case I think is due to the generalization of the concepts. If I understood correctly, when we hold our breath and the response hit, we get peripheral vasoconstriction and central vasodilation - the best of both.

My experience with the effect of preserved sausages (nitrite/nitrate) on apnea was disastrous.... I don't recommend it!

[efattah]

Did you know that nitrate and nitrite are also antilibido agents? Sodium nitrate is given to men as a form of chemical castration.

Not a good diet for a porn star.

Eric, Whats up with eating less onions and garlic? Something to do with BP?

Onions and garlic lower BP a lot; this reduces O2 consumption significantly, but increases the risk of a blackout, especially a blackout during packing.

However, recent evidence/experiments with FRC diving imply that a diet high in garlic is ideal for FRC -- primarily because with FRC there is no risk of BO from packing, and there is a lowered risk of SWB from many factors. This allows the FRC diver to take full advantage of the lowered O2 consumption caused by garlic. Don't take that at face value, it needs more experiments to be proven.

Garlic both thins the blood and dilates blood vessels.

Soo, what would be roughly a good dosage of pure citric acid?

I wonder what is in the lemon that does it for apnea.
As far as I know body strictily regulates levels of vitamin C in the blood, no matter how much of it you eat...so I would be tempted to exclude that one.

[samdive]

I think its the acidity that causes the problem. I get eczema and eating acidy food particularly citrus fruit makes it flare up violently - so I don't think neat citric acid is a great idea!


interesting facts about the sausages - next time I get a Stalker I will try feeding him copious quantities of hot dogs!

Hi Tim,

Of course it will help, I'm used to spicy food (love it) and had learnt the lesson the hard way, so before a dive weekend i try to control my self for two days, sometimes is not enough. About cirtus fruits, i've been told they are advised against because of methane is that true?... So, as i see, i'm not doing quite well and there are many things to focus on...

By the way thank you...
Sigi..

Eating lemons or doing CO2 tables - now there's a hard choice.

[Mlaen]

So. would eating leamons had the long term effect in CO2 tolerance like doing CO2 tables?

Sodium Nitrate...hmmm...where have I heard that before? Oh right, it's great for homemade explosives! In fact, if I remember right (which is rare), it is used commonly as a fertilizer.

The explosive of choice for the people who blew the bomb in Oklahoma City a few years back.

Also previously used by the US military to keep "hormone levels down" during basic training. (Affectionately termed "Salt Peter" by the men.)

I think you're referring to ammoniun nitrate with the explosives stuff? http://en.wikipedia.org/wiki/Ammonium_nitrate

Homeland Security, do not read beyond this line!

Both work pretty good.
Believe me. I've blown a shitload of things to the moon when I was a kid.

Back to the topic plx, before I say things that I'll have to deny in court !

[Aquagenic]

See, I told you it is rare for me to remember right. I was mixing the two up, one was for a napalm recipe, one was for a smoke bomb recipe...my mistake.

I totally agree with Ricochet though, back to the topic...
