Gas phase separation during decompression in man:ultrasound monitoring
decompression human Doppler
2009/7/20
During two dive series, one to 132 fsw and one to 210 fsw, Doppler ultrasonic bubble detectors were used to monitor venous gas bubbles in divers during decompression and for 30 min thereafter. Various...
Maximal physical-work capacity of man at 43.4 ATA
human Maximal Voluntary Ventilation respiratory
2009/7/20
Maximal physical-work capacity of man at 43.4 ATA.
Effects on man of 30-day exposure to a PICO2 of 14 torr (2 %):application to exposure limits
CO2 carbon dioxide exercise psychomotor test electrobiological
2009/7/17
Pulmonary function, acid-base balance, renal electrolyte excretion, hematology, biorhythms and psychomotor test results were studied in six men during 30 days of exposure to a PICO2 of 14 torr (FICO2 ...
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...
Effect of compression rate on use of trimix to ameliorate HPNS in man to 686 m (2250 ft)
decompression human compression rate trimix high pressure neurologic syndrome heliox Psychological Psychomotor Performance
2009/7/16
Previous man dives, in a series designed to evaluate the physiological effects of helium, nitrogen, and oxygen (trimix), investigated the comparative effects of 5 percent vs. 10 percent nitrogen with ...
Autopsy and experimental observations on factors leading to barotrauma in man
human Autopsy barotrauma
2009/7/15
Morbid anatomical data have been examined in detail from 13 fatal diving accidents in which the primary cause of death was due to pulmonary damage. In addition, the observations on 6 cases of experime...
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 ...
Breath-hold duration in man and the diving response induced by face immersion
cold exercise CO2 carbon dioxide Breath-hold face immersion
2009/7/9
The objective of this study in 5 selected volunteer subjects was to see whether the circulatory diving response which is elicited by breath holding and by cold water on the face would affect the durat...
Sleep organization in man during long stays at 30 and 40 bar in a helium-oxygen mixture
saturation retinal eye decompression helium heliox sleep
2009/7/8
Sleep organization was studied during 5 dives with long holds (from 6 to 15 days) at 30 and 40 bar in a helium-oxygen mixture. In total, 16 professional divers participated in these saturation dives; ...
Effect of inspiratory-phase negative pressure breathing on urine flow in man
negative pressure urine
2009/7/8
We investigated the effect of negative pressure breathing during the inspiratory phase only (intermittent NPB) in 9 healthy male subjects who were in a sitting position and had no food or fluid intake...
Cardiovascular responses to upright tilt in man during acute exposure to 3 atm abs air
cardiovascular hyperbaric cardiac output position
2009/7/8
To examine the effect of acute hyperbaric exposure on cardiovascular response to orthostasis, a passive 70 degrees head-up tilt (HUT) test was performed for 15 min in a simulated compressed-air hyperb...
In the present study a total of 44 dry skulls and 500 skull films from the Sivas region of Turkey were examined to determine whether or not the interparietal bone was present. The incidence of interpa...
Flexion Contractures in a Diabetic Young Man (Rosenbloom Syndrome)
Diabetes Mellitus Rosenbloom syndrome limited joint mobility
2009/6/30
Limited joint mobility syndrome was initially described by Rosenbloom as painless limitation of the fingers and large joints in association with short stature, thick, tight, waxy skin, delayed sexual ...
Using data compiled by the Brussels Cadaver Analysis Study on 13 unembalmed cadavers, this study examined the validity of assumptions often made concerning the role of the skin and adipose tissue laye...
Diurnal renal responses in man to water loading at sea level and 31 atm abs
hyperbaric renal hydration Diuresis Circadian Rhythm
2009/6/9
The hyperbaric environment causes a sustained diuresis accompanied by normal water intake and a decrease in insensible water loss. The maintained water intake may be necessary for the maintenance of w...
