Hyperbaric arthralgia during helium-oxygen dives from 100 to 850 fsw.
Glucose homeostasis of man in helium-oxygen at 1-50 atmospheres absolute.
Tremor is a well-recognized manifestation of the high pressure nervous syndrome (HPNS). As such, its measurement and analysis during deep hyperbaric exposures can be an important index of central nerv...
Thermal homeostasis of resting man in helium-oxygen at 1-50 atmospheres absolute.
Bone growth and composition were studied in growing rats following continuous long-term hyperbaric exposure. Six groups of eight rats each were maintained at 21 ATA He-O2 (200 mm Hg O2) and six groups...
Divers under hyperbaric conditions experience a marked deterioration in speech intelligibility. Included among the possible features that contribute to speech degradation is change/distrotion of speak...
The effects of two antipyretics, aspirin and acetaminophen, were studied under hyperbaric helium-oxygen conditions. Groups of yeast-fevered rats were given three different doses of each antipyretic in...
During a series of three saturation dives to simulated depths of 1000, 1200, and 1400 fsw at the Ocean Simulation Facility, measurements were made to establish the rate of heat loss of unclad divers i...
Helium at pressures of 20 to 70 atm in the presence of air found to stimulate growth of Streptococcus faecalis, Escherichia coli, and Staphylococcus aureus, mainly by increasing the rate of exponentia...
Excursion ascents were performed during a series of experimental helium-oxygen saturation dives ranging between 150 and 1000 fsw to study the limits of multiple and extended duration excursions both d...
One-hundred twenty three guinea pigs, randomly divided into four groups, were exposed to the following normoxic environments: Group I, 1 atmosphere absolute (ATA) air; Group II, 1 ATA helium-oxygen (h...
Word-list intelligibility scores of unprocessed speech (mean of 4 subjects) were recorded in helium-oxygen atmospheres at stable pressures equivalent to 1600, 1400, 1200, 1000, 860, 690, 560, 392, and...
The capacitance coefficient beta of an ideal gas mixture depends only on its temperature T, and its value is derived from the ideal gas law (i.e., beta = 1/RT, R being the ideal gas constant). But rea...
The effects of room-air normoxic (22 degrees C +/- 1 degree C), 1.2-ATA He-O2 (400 mmHg PO2, 29.0 degree C +/- 1 degree C), and 21-ATA He-O2 (400 mmHg PO2, 32.5 degrees C +/- 1 degree C) environments ...
Excitability of the Hoffmann (H) reflex was studied in 6 subjects at pressures of 40 to 70 bar during two trimix exposures (10percent N2, 0.5 bar O2, the remainder He; Atlantis II and III simulated di...
