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...
Statistical aspects of the design and testing of decompression tables
decompression sickness human Probability decompression table design method
2009/7/15
Before a decompression procedure is recommended for general use it is subjected to a limited number of human trial dives. Based on the trial, one attempts to reject unsafe procedures but accept those ...
Pressure in the treatment of spinal cord decompression sickness
decompression sickness spinal cord animal dog
2009/7/15
Previous work had shown that a Po2 of about 2.0 bar was the optimal Po2 for the treatment of spinal cord decompression sickness (DCS). With 20 anesthetized dogs the hypothesis was tested that pressure...
Oxygen in the treatment of spinal cord decompression sickness
decompression sickness spinal cord Oxygen spinal evoked potentials animal dog
2009/7/15
Twenty-five anesthetized dogs were used to find the optimum Po2 for the delayed treatment of spinal cord decompression sickness (DCS). They were instrumented for the measurement of physiological varia...

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...
Skin antisepsis during steady-state hyperbaric exposure and subsequent decompression
decompression human infection
2009/7/15
A custom-made container for the transfer of bacteriological sampling pads was used in a trial to test the feasibility of human skin disinfection during saturation or steady-state diving and subsequent...
Gas phase formation and Doppler monitoring during decompression with elevated oxygen
decompression human
2009/7/15
Subjects in 150 man-dives were precordially monitored with a 5-MHz Doppler ultrasound bubble detector. These measurements were made during a series of dives conducted to test decompression tables that...
Cardiovascular effects of induced decompression sickness in sheep fetus
decompression sickness Cardiovascular animal sheep fetus Pregnancy
2009/7/15
Ten chronically catheterized near-term sheep fetuses were used to study the effect of induced intravascular bubbling on fetal placental vascular dynamics and fetal regional blood flows. Fetal blood pr...

Decompression from a deep nitrogen/oxygen saturation dive--a case report
decompression nitrogen human nitrox
2009/7/15
Ten divers participated in a 4.5 d nitrogen/oxygen saturation dive to 165 fsw. There were daily 2 h excursions to 61 msw (200 fsw). The divers breathed air during the excursions and 0.51 bar (0.5 atm)...
Reversal of pressure-induced tremors in rats by step decompression and by inert gases
decompression animal mice
2009/7/15
A method for continuously recording the motor activity of pressurized rats was used to monitor their condition after 1) holding pressure constant after compression, 2) decompression, and 3) adding nit...

decompression sickness risk factor obesity Body Weight human diver health
2009/7/15
The relationship between the health status and physical characteristics of 185 U.S. Navy divers and their risk for experiencing decompression sickness was examined utilizing historical cohort design. ...
A method for measuring nitrogen elimination after air diving has been developed in which a subject breathes air instead of oxygen or helium-oxygen. Accuracy is improved with this method because only n...
