Measurement of helium elimination from man during decompression breathing air or oxygen
human helium elimination decompression
2009/7/20
Air breathing was compared with oxygen breathing during decompression from an 80-20 percent helium-oxygen dive to a depth equivalent to 120 fsw (4.6 ATA) in a dry chamber to see which was the most eff...

Direct measurement of helium elimination in mice.
A method for measurement of the bubble formation threshold in biological liquids
measurement bubble biological liquids pressure-time course
2009/7/20
Liquid under pressure is saturated with a given gas, such as argon, nitrogen, or air, by circulation through a column of gas exchangers. A sample of the gas-saturated liquid is isolated in a test cham...

Transcutaneous measurement of PCO2 at high ambient pressure (41 bar)
transcutaneous oxygen CO2 carbon dioxide animal rat hyperbaric
2009/7/10
The accuracy of transcutaneous CO2 monitoring with the Kontron CO2 sensor was studied during compression to 41 bar and subsequent decompression. The PCO2 was stable and accurate during the test of the...
Characterization and measurement of elastance with application to underwater breathing apparatus
underwater breathing apparatus elastance respiratory load
2009/6/12
The elastic loads inherent in underwater breathing apparatus (UBA) can affect diver performance. This work quantitatively examines elastance, its measurement by static tests, and its relationship to U...
Measurement of oxygen concentration in delivery systems used for hyperbaric oxygen therapy
hyperbaric equipment oxygen delivery breathing mask breathing hood
2009/6/8
Efficient delivery of oxygen is important during hyperbaric oxygen therapy. We compared two systems in common use, and developed a method to ensure that O2 delivery was adequate during treatment. The ...
We describe a method of using a micro-tip transducer to measure cerebrospinal fluid pressure (CSFp) through a lateral ventricular cannula in unanesthetized, restrained, non-stressed rats. The mean val...
Measurement of cerebral blood flow in rats and mice by hydrogen clearance during hyperbaric oxygen exposure
CO2 carbon dioxide hydrogen hyperbaric cerebral blood flow air animal mice
2009/6/8
The hydrogen (H2) clearance method was adapted for the measurement of regional cerebral blood flow (rCBF) in anesthetized rats and mice during hyperbaric oxygen (HBO2) exposure. Polarographic platinum...
Measurement of fatigue following 18 msw dry chamber dives breathing air or enriched air nitrox
Analysis of Variance air Atmosphere Exposure Chambers Atmospheric Pressure Attention Decompression
2009/6/4
Many divers report less fatigue following diving breathing oxygen rich N2-O2 mixtures compared with breathing air. In this double blinded, randomized controlled study 11 divers breathed either air or ...
