saturation cardiovascular dry hyperbaric
2009/7/14
Cardiovascular deconditioning (CD) has been reported to occur in weightlessness, bed rest, and head-out water immersion. An expanded intrathoracic blood volume results, at least initially, in all thes...

The effects of cold acclimation (CA) on the cardiorespiratory responses to cold air and water stress tests (CST) were studied in 7 males before and after a CA program of daily 90-min cold water (18 de...
Cardiovascular changes in anesthetized rats during exposure to 30 bar
Cardiovascular animal rat hemodynamic
2009/7/9
The effect of exposure to 30 bar (PHe = 29.0 bar, PN2 = 0.8 bar, PO2 = 0.2 bar) on left ventricular pressure, cardiac contractility, heart rate (HR), and arterial pressure was studied in anesthetized ...
An investigation of cardiovascular reflexes during a trimix saturation dive to 450 msw (GUSI 17)
human baroreflex cardiovascular saturation trimix
2009/7/8
The study examines the hypothesis that the carotid sinus heart rate baroreflex responses are changed in human subjects on exposure to 450 msw. Baroreceptor reflex changes in heart rate (expressed as m...
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...
Moderate hypercapnia:cardiovascular function and nitrogen elimination
CO2 carbon dioxide nitrogen elimination hypercapnia nitrogen cardiovascular
2009/6/12
Elevated carbon dioxide concentrations frequently encountered in diving operations may have cardiovascular effects. If so, changes in nitrogen loading and elimination may be induced. To study this pos...
