FS: Hyperbaric chamber

[John Finucan]

For Sale: Wallace Altitude Hyperbaric Tent; 9000 foot model. Fits over
queen size bed with long connection to hyperbaric generator/power module to
be placed in the next room. Cost $5500 new, letting go for $3000. Much
cheaper than moving to Boulder, CO. See this unit at www.altitudetent.com .
Will split shipping FedEX COD with cashiers check. Call to discuss further.

Just for the record, if it simulates high altitude conditions, it's a
hypObaric tent. A hypERbaric chamber simulates pressure conditions
under water.

Actually, these chambers can be used in both ways. If trying to stimulate
RBC production, then one would lower the tent air pressure (high altitude).
If trying to recover from hard training, then jacking up the pressure
(hyperbaric) will supposedly flush the tissue with oxygen for faster
recovery. However, this claim is suspect, as the body typically attains
optimal PO2 levels in the blood with normal sea level pressure of 760 mm Hg.

Well, a tent won't maintain much of a positive pressure gradient.
Better to enrich the O2 content of the air breathed.

If you're below optimal, you'll get back to optimal faster with
hyperbaric O2. PO2 levels correlate dependent on ambient partial
pressure of oxygen.

Yeah, but the "tent" type of chambers don't do anything to the
air pressure inside, they just decrease the percentage of oxygen
in the air. What research is there to prove that lowering the
oxygen without lowering the pressure works the same?

[Andrew Coggan]

While the physiological responses to hypobaria and hypoxia are not
identical, they are very, very similar. This would be expected, since
the dominant influence is the reduction in PO2. In any case, hypoxia per
se has been shown to stimulate secretion of erthyropoetin, so that makes
the question rather moot...I don't know if anybody has published any
data showing that using these tents as prescribed will elevate
hematocrit, but if they don't it would simply be a matter of "dose"
(i.e., it may require longer exposure to a lower PO2 - but then again,
it may not).

Actually it would work. The body responds to the partial pressure of
oxygen.
