Five infants had hypoxia <40 torr and 5 needed a continuous infusion of epinephrine >1 ng/kg/min.
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).
