Worry about dissolved blood gasses coming out of solution. ok, so the "bends" is the bigger problem then. and i guess a "no pressure" suit would require much longer camping in airlock than 5psi suit. A "no pressure suit" means you die. especially true if you breathe in at 5psi and blood flows to no pressure areas of body. Where did you get this 'no pressure' idea? but if low/no pressure has instant effects on the blood releasing disolved gases, wouldn't the same happen to its boiling point? Do divers have problems with blood boiling? if the skin bloats in lower pressure, couldn't they make a suit that is easier to get in and let body bloat create the pressure? Because you can't reliably create consistent pressure everywhere that way AND you'd like to not injure people. also, have they solved the issue of anus and urethra? wouldn't lower external pressure result in far more difficult time for muscles to contain what's in body? assuming perfectly moulded suit, would mechanical fabric pressure on anus do the trick or does this really require gaseious pressure to reach the muscles so there is equilibrium? You fart a lot when you go from 14.7 PSI to 5 PSI. They don't tell you this. I when to a talk by a U2 pilot once. As a data point, they did open the mask up at 70,000 feet as necessary. The aircraft was put on autopilot allowing sleeping time. Drinking and eating and nose scratching/puking were allowed. |
