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...
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...
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...
Decompression profile and bubble formation after dives with surface decompression: experimental support for a dual phase model of decompression
Animal swine Decompression etiology Diving
2009/6/5
The present study was initiated in order to determine the effect of decompression profiles on bubble formation following surface decompression using oxygen. Following an air dive to 496 kPa (130 fsw) ...
The life-saving effect of hyperbaric oxygenation during early-phase severe blunt chest injuries
Hyperbaric Oxygenation Human blunt chest injury trauma cardiorespiratory injury
2009/6/2
The effect of hyperbaric oxygenation (HBO2) on survival during the early phase of severe blunt chest injury (BChI) has not been elucidated. Our aim was to investigate this effect on human victims of B...
Oxygen-Enhanced Breath-hold Diving, Phase I: Hyperventilation and Carbon Dioxide Elimination
breath-hold Hyperventilation carbon dioxide loss of consciousness
2009/5/6
Hyperventilation (HV) is commonly used to extend breath-hold time by eliminating carbon dioxide to delay the hypercapnic stimulus to end breath-hold. The chief hazard is that loss of consciousness ma...
