Converting standard air decompression tables for no-stop diving from altitude or habitat
decompression human altitude
2009/7/20
Using the phase equilibration theory of Hills (1966), as modified by Hennessy and Hempleman (1977), it is possible to predict formulas for converting standard air decompression tables for no-stop divi...
Visual evoked responses and EEG's of 16 divers breathing air at 7 ATA
human electrophysiological
2009/7/20
This study is an assessment of individual differences in electrophysiological response under diving conditions normally conducive to nitrogen narcosis. A group of 16 men made two dives each to approxi...
Roles of nitrogen,oxygen,and carbon dioxide in compressed-air narcosis
human nitrogen carbon dioxide oxygen compressed-air narcosis
2009/7/20
In an attempt to determine the roles of nitrogen, oxygen, and carbon dioxide in compressed-air narcosis, the effects on performance (mental function and manual dexterity) of adding CO2 in various conc...
Testicular blood flow and plasma testosterone concentrations in anesthetized rats previously exposed to air at 6 ATA
plasma testosterone animal rat air Testicular
2009/7/17
Testicular blood flow and peripheral testosterone levels were measured in sodium pentobarbitone anesthetized adult rats within 3 h of exposure to air at 6 ATA for 24 h. The animals appeared clinically...
In mixed-gas diving theory, the equivalent air depth (EAD) concept suggests that oxygen does not contribute to the total tissue gas tension and can therefore be disregarded in calculations of the deco...
Combined effects of ethanol and hyperbaric air on body sway and heart rate in man
human ethanol drinking narcosis
2009/7/17
Eight amateur divers took part in crossover experiments to study the combined effects of ethanol (0.72 g/kg b.wt.) and hyperbaric air (4 and 6 ATA) on heart rate and body-sway movements. Body sway wit...
Narcotic effects of nitrous oxide and compressed air on memory and auditory perception
human Narcotic perception air nitrous oxide
2009/7/17
Three experiments were conducted to examine the effects of 35percent N2 O (nitrous oxide) on human memory and auditory perception. In Experiment I, dichotic listening performance was found to be impai...
Size distribution of intravascular air emboli produced by decompression
decompression bubbles diameters lungs organ
2009/7/16
Intravascular bubbles formed by decompression have been measured in 7 living dogs to give 14 different determinations of size distribution. Larger bubbles were estimated by the terminal rise velocity ...
Successful therapy of cerebral air embolism with hyperbaric oxygen at 2.8 ATA
human case report hyperbaric oxygen therapy
2009/7/16
A 60-year-old male patient suddenly developed blindness, agitation, and disorientation 36 h after coronary bypass surgery. Onset of symptoms followed efforts to clear an air-filled radial artery cannu...
Observations on no-stop and repetitive air and oxynitrogen diving
decompression nitrogen human nitrox repetitive diving
2009/7/16
The historical origins of the respective air decompression schedules of the British and United States Navies are reviewed with particular reference to the repetitive diving rules. No-stop diving is al...
Air and nitrox saturation decompression:a report of 4 schedules and 77 subjects
decompression saturation report
2009/7/15
Seventy-seven subjects were decompressed from air or nitrogen-oxygen (nitrox) saturation exposures at 18.3 to 40.2 meters sea water (msw) [60 to 132 feet sea water (fsw)] using four different decompre...

human medical examination commercial
2009/7/15
One thousand workers intended to be employed in a compressed air tunneling project in Hong Kong had preemployment medical examinations for fitness to work in compressed air. Only 69.3percent were decl...
Decompression incidence in air- and liquid-breathing hamsters
decompression Fluorocarbons liquid breathing breathing animal hamster
2009/7/15
The effects of hyperbaric compression on heart rate, rectal temperature, respiratory rate, bubble formation, and survival were studied in three groups of anesthetized golden hamsters (Mesocricetus aur...
Cardiac arrhythmias and heart rate changes in prolonged hyperbaric air exposures
human Cardiac arrhythmia heart rate exercise air
2009/7/15
Daily resting and exercise electrocardiograms from 81 healthy subjects taking part in eight different air saturation chamber experiments at depths of 2-132 ft sea water gauge (fswg) were recorded and ...
Two unusual cases of severe dysbarism after compressed air work in Hong Kong
decompression sickness human case report pulmonary chokes
2009/7/15
Two cases of unusual severe dysbarism are reported. One case occurred after working in compressed air at a pressure of 2.05 kg/cm2 (29 psi) for a duration of 27 min; the second case, after working for...
