[quote:nomuse (not logged in) 2380183:MV8yMDcxODA4XzM1MzA3NTk3XzFFRTFEMkUy] [quote:DUCM900:MV8yMDcxODA4XzM1MzAyMjA4XzZEMEQ5MjhE] [quote:DUCM900:MV8yMDcxODA4XzM1Mjg2OTYwXzREOTc1REVC] Another issue is how they decompressed, getting in and out of the lunar module. [/quote] Astronauts suit relative pressures were in about 5 psi when the LM cabin pressure was 3.5 psi.. Now, anyone knows what is the min pressure required by a human for keeping the stuff alive/healty? / [/quote] No, that doesn't sound right. A7L was run at 3.7 psia. LM cabin was normally pressurized to 4.8 psia. But during exit, they ran the A7's up above 4.7 first (since they started at cabin pressure). Dump took a couple of minutes. In any case, the reason you need to flush your lungs before EVA from the ISS is that the latter is a mixed-gas system. If you aren't breathing in any nitrogen, you aren't going to have a problem with nitrogen bubbles. (A few psi either way isn't going to do it, either -- otherwise everyone that took a commercial airliner would be worrying about getting the bends.) As per the other question, the rule of thumb is within 50% of sea-level partial pressure of oxygen. Since oxygen is about 20% of our ordinary atmosphere, a pure oxygen mix at 1/5 sea level is equivalent. There's a couple other factors -- water vapor pressure for one -- but it works out that 1/3 atmosphere at 100% oxygen is about equivalent to being at mild altitude (aka, like Denver). [/quote]

That's a simple fact.
