Subaquaticus recently posted to an old 2002 thread, which brought it up today on "Latest discussions" from threads on db’s home page. This gave me the opportunity to re-read an Eric Fattah post where he said this,
“Even though you only have 5 litres of blood (of which about half is water), your body contains around 50 litres of water. Not much O2 dissolves in water, but 50 litres is a lot, and you store about 5% of your O2 store in this water, which is referred to as the 'tissue' oxygen store. When your SaO2 drops below 80%, you start stealing oxygen from this 'tissue' store, and you enter 'deep tissue hypoxia'. This 'oxygen debt' can take a LONG time to replenish once you deplete it (because lactic acid also accumulates in your organs). Thus, if you do a single static where you go below 80% SaO2 for any length of time, you will enter into an oxygen debt which could take half an hour to replenish. If you breathe up quickly, within a couple of minutes your blood will be fully re-oxygenated, but your tissues will continue slowly stealing O2 from your blood, because they are still hypoxic. So, if you don't allow the 30 minutes to replenish the tissue store, you start out with about 5% less O2.”
Now I know I and other have experimented with stabilized O2 liquid products such as Hyrogen Peroxide, etc., with no real positive static results. Then there has been the all-out one static approach that Tom Sietas popularized that many of us have played with in the past year.
Is it just possible that the reason I, and maybe others, found no benefit in using stabilized O2 products was that I was depleting the O2 tissue stores in warmup statics where I took my SaO2 to below 80%? Therefore even if I did have a tissue saturation of O2 above normal before the start of the series, the saturation was less than normal and the benefit gone by the time I went for my max. But if doing the one static no warm-ups approach, would there be a benefit in drinking stabilized liquid O2 to saturate the tissues?
Those 50 litres of water Eric talks about sure sound intriguing to me! From what I have read, 10 ppm of O2 in water is a high amount, but stabilized O2 liquid can hold as much as 1000 ppm! Drinking it right before a static does not sound very promising, because the ability of the O2 to go from the stomach (where the water will be right after drinking) to the blood stream is small, but drinking it for several hours before to saturate all the tissues of the body?
