Five infants had hypoxia <40 torr and 5 needed a continuous infusion of epinephrine >1 tig/kg/min. The operating pressure in the analysis chamber was in the 10-9 torr range. The gas was ultrahigh-purity hydrogen or noble gas-hydrogen mixture (90/10%) at 2 torr total pressure. Corresponding hydrogen pressures are 1, 1.5 and 1.5 torr, respectively. For nitrogen, collisional coupling occurs at pressures exceeding 0.5 torr.! This tube is prefilled with 1 torr helium gas initially. Over the range of approximately 30-80 torr, developmental score increased 8.8 points for every 10 torr increase in tension of carbon dioxide (p=0.002). The tube is initially filled with helium gas at 1 torr. The partial pressure of the hydrogen gas was given by the incremental increase in total gas pressure monitored by a 0-10 torr absolute pressure gauge. During the heat-up the cell was periodically pressurized with hydrogen (99.999% purity) to approximately 100 torr and subsequently evacuated to purge gaseous contaminants from the system. The brain, with reduced but persisting metabolism, could have utilized the remaining oxygen for the initial 20 minutes, since mitochondria can take up oxygen under very low tensions (<1.0 torr). The pressure at the melting point is 14,500 torr. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The space between the concrete enclosure and the aluminum test chamber is pumped down to a pressure of 20 torr (0.5 psia) during a test.
