How to Acclimatize in the Comfort of Your Own Home (for only $7,000)

Adam Helman has this interesting post over in the cohp.

For those with more cash in their wallet than time on their hands to properly acclimatize ….(such as a practicing physician???)

I read at another website that the tent system costs $7,000 .

FAQs (Frequently Answered Questions) are discussed here -

Some answers to the most obvious questions:

* The tent or bed system in standard configuration simulates 9,000 feet
elevation by removing oxygen ONLY, i.e. not all air components equally.
The lowered oxygen partial pressure results by lowering oxgyen’s fraction
from 21% (i.e. standard atmosphere) to about 14.5%.

* In a configuration obtainable with a special adapter, the system(s) can
simulate up to 14,500 feet. The hypoxic website fine print claims that
special requests by serious mountaineers will be entertained to configure
the system for simulating up to 20,000 feet.

* CO2 is removed by the large airflow rate that allows fresh air to enter
at 48,000 liter / “night” (?) of sleep.

* Long-term adaptation to high altitude relies upon a rise in hematocrit,
the fraction of blood volume due to red cells. Some people enjoy a rise
after using this system – others do not.

These changes in hematocrit
occur on a time scale far too long to be observed in people climbing
a mountain – where acclimatization results only from the relatively
rapid shifts in blood chemistry, pH levels, CO2 concentration etc … .

In theory a rise in hematocrit would be a considerable advantage to
anybody climbing to extreme altitude.

I in no way advocate use of these systems. However their mere existence is noteworthy as it indicates that a considerable market exists for high-altitude training of athletes from diverse sports.

I suspect that if an employer learned that a worker is going to sleep in a low-oxygen environment that some “interesting” discussions might ensue.

I would claim that it is not his business any more than what said worker might do after-hours in general that are PROVEN to be harmful (smoking, drinking, etc…).
In contrast, entire societies live and work at high altitude.

No ill-effects result from “living the high life”: just LOOK at the world-class
productivity of the Bolivian and Tibetan economies!!
