Effects of helium gas on heart rate and oxygen consumption in unanesthetized rats.
Heart rate and respiratory frequency in hydrostatically compressed,liquid-breathing mice
decompression liquid breathing
2009/7/20
The effects of hydraulic compression on heart rate and respiratory frequency were studied in liquid-breathing, hypothermic (17-31 degrees C) mice. Increasing the hydrostatic pressure caused a bradycar...
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...
Effects of hyperbaric oxygen on heart,brain,and lung functions in rat
hyperbaric rat heart brain lung oxygen pressures
2009/7/16
Electrocardiogram (ECG), electrocorticogram (ECoG), and respiratory rate (RR) were monitored in awake, unrestrained rats during continuous exposure to 1, 3, and 5 ATA O2 until death. The RR showed a c...

2009/7/15
The efficacy of using a diver's heart rate (HR) response to work performed formed in the open sea to estimate the oxygen uptake (VO2) and work stress by general and depth-specific regression equations...
Cardiac arrhythmias and heart rate changes in prolonged hyperbaric air exposures
human Cardiac arrhythmia heart rate exercise air
2009/7/15
Daily resting and exercise electrocardiograms from 81 healthy subjects taking part in eight different air saturation chamber experiments at depths of 2-132 ft sea water gauge (fswg) were recorded and ...
