Visual evoked responses,EEG's and reaction time during a normoxic saturation dive,NISAT I
nitrogen human Electroencephalography
2009/7/20
Three Navy divers were exposed to a normoxic breathing mixture at 7.0 ATA for seven consecutive days. Visual evoked responses (VER's), electroencephalograms (EEG's) and simple reaction time (RT) were ...

The adrenocortical endocrine subsystem has been demonstrated to enhance mammalian tolerance to harsh environmental conditions, including hypoxia and temperature extremes. In a series of factorial expe...
Heat loss and tolerance time during cold exposure in heliox atmosphere at 16 ATA
human cold thermal heliox Protective Clothing
2009/7/16
Four different types of protective clothing and three different methods of heat conservation protection were evaluated during an exposure to 4 degrees C cold in a heliox atmosphere at 150 msw. The div...
Effects of variations in time pattern of nitrogen addition on development of HPNS in mice
drug high pressure nervous syndrome animal mice heliox trimix
2009/7/16
The effect of change in injection pattern in nitrogen on threshold pressures of three symptoms associated with compression in helium/nitrogen atmospheres was explored. Excitement threshold pressures d...
Decrease of ether induction time after exposure to dysbaric conditions in rat
decompression ether anesthesia animal rat
2009/7/16
In 22 adult male albino rats (means = 565 g) it was consistently observed that the time required to anesthetize them with 5 ml of diethyl ether after a hyperbaric exposure of 6 ATA using compressed ai...
Cerebral arterial air embolism: II. Effect of pressure and time on cortical evoked potential recovery
submarine human Cerebral arterial air embolism cortical evoked potentials animal dog
2009/7/15
In a dog model of cerebral arterial gas embolism we studied the relative merits of several different treatments: air breathing at 2.8, 6, 8, and 10 bar (60, 165, 230, and 300 ft), and oxygen breathing...
Origin and time course of gas bubbles following rapid decompression in the hamster
decompression bubble animal hamster
2009/7/15
Because conflicting results have been obtained in studies of the hamster (Mesocricetus auratus) microcirculation following rapid decompression, we were interested in the origin of bubbles in the cheek...
The hypothesis that the diving response, recorded as diving bradycardia during submersed breath holding in man, would enhance his breath-holding time was tested. Five certified scuba divers served as ...
Visual reaction time performance preceding CNS oxygen toxicity
human oxygen toxicity visual
2009/7/14
The visual reaction time performance of divers experiencing CNS oxygen toxicity was assessed during the development of closed-circuit 100percent oxygen breathing diving schedules at the U.S. Navy Expe...
Venous gas embolism: time course of residual pulmonary intravascular bubbles
CO2 carbon dioxide nitrogen pulmonary air animal dog Venous gas embolism
2009/7/9
The time course of pulmonary intravascular air emboli was studied in anesthetized dogs. In one series of experiments air was infused into the right atrium at 0.10 ml.kg-1.min-1 or 0.25 ml.kg-1.min-1 f...
