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...
Decompression sickness in human beings exposed to high ambient pressure is thought to follow from gas bubble formation and growth in the body during return to low pressure. Detection of Doppler-shifte...
Many cases of decompression illness occur in divers using recommended decompression tables. Doppler ultrasound has been used for over 20 yr and has shown the presence of venous bubbles in asymptomatic...
In the present study, experimental exposures to hyperbaric oxygen (HBO2) were performed (30-min exposure to 2.8 bar (280 kPa) pure oxygen). During all phases of the experiment, blood flow velocity in ...
Since the 1960s,decompression illness after breath-hold diving has been widely debated. The aim of this study was to detect circulating bubbles after breath-hold diving in underwater fishing divers. W...
To determine the influence of a saturation dive on cardiac function, Doppler-echocardiographic measurements were compared at sea level and during a 36 atm (3,650 kPa) He-O2 dive (gas density: 7 g/lite...
The vasoconstrictive response to hyperbaric oxygen (HBO2) therapy was non-invasively quantified in eight healthy volunteers at 1.95 and 2.5 atm abs (197.5 and 253.2 kPa; multiplace chamber, air enviro...
To determine if professional diving leads to morphologic and/or functional cardiologic changes, Doppler-echocardiography was performed in 20 professional saturation divers (average 15 yr diving experi...
Menstruation has been described as risk factor for neurological decompression sickness in divers. In considering this for paradoxical gas embolism, we hypothesized that there may be a link between cyc...
A pilot study was carried out to examine the incidence of doppler-detectable circulating bubbles in hyperbaric chamber attendants following routine chamber treatment profiles. Bubbles were detected...
A review of the literature on the use of transcutaneous Doppler to detect circulating venous bubbles occurring after hyperbaric exposure, with emphasis on the detection of bubbles occurring after ...
Before 1990 the drift divers of the 13 pearling companies working out of Broome all dived using the methods described in another paper but with individual variations, such as the rate of ascent, fr...
