Effects of head-out water immersion on cardiorespiratory responses to maximal cycling exercise
human head-out immersion scuba breathing exercise cardiorespiratory
2009/7/20
Our objectives were to determine effects of head-out immersion (HOI), scuba breathing, and water temperature on cardiorespiratory responses to maximal aerobic work. Measurements of VO2, VE, and heart ...
Respiratory gas exchange and lung perfusion in man during and after head-out water immersion
CO2 carbon dioxide carbon monoxide pulmonary human CO
2009/7/20
The respiratory gas exchange for O2, CO2, and CO has been studied in nine healthy male subjects before, during, and after head-out water immersion. Distribution of lung perfusion and ventilation were ...
Influence of hydrostatic compression of the chest and intrathoracic blood pooling on static lung mechanics during head-out immersion
human immersion intrathoracic blood pooling respiratory
2009/7/20
The effect of water immersion on static lung volumes and pressure-volume curves was studied in five subjects. A special container allowed measurements during nonimmersion, head-out immersion, and thor...
Physiological responses to head-out immersion in water at 11 ATA
hyperbaric cardiac output human head out immersion immersion diuresis
2009/7/17
Cardiorespiratory, thermal, and renal responses to a 30-min head-out immersion in 15 degree C water were studied at 1-ATA air and 11-ATA helium-oxygne environments in four male subjects wearing dry su...
Field study of ventilation in volunteer scuba divers during head-out immersion
human ventilation immersion exercise respiratory
2009/7/15
Seven subjects had spirometric studies during head-out immersion before and after working at depth in coral research. Under the variable environmental conditions of a field study the seven subjects de...
Cardiovascular and renal responses to head-out water immersion in canine model
cardiovascular cardiac output dog animal immersion renal
2009/7/15
Water immersion (WI) of anesthetized dogs to the midcervical level in the vertical sitting position under thermoneutral conditions (38 degrees C) leads to generalized increases in regional blood flows...
Cardiac output by impedance cardiography during head-out water immersion
human immersion cardiac
2009/7/14
This study was undertaken to ascertain the suitability of impedance cardiography for qualifying cardiac output during water immersion where the electrodes were wet. The cardiac output was compared dur...
Seadragon VI:a 7-day dry saturation dive at 31 ATA.VI.Hyperbaria enhances renin but eliminates ADH responses to head-up tilt
human plasma antidiuretic hormone plasma renin activity plasma cortisol aldosterone
2009/7/14
Three male subjects were passively tilted from a supine to a 90 degree head-up standing position on 2 d each at 1 and 31 ATA, then on 1 d of the postdive period. On each day the subjects were tilted o...
Fluid and cation changes during head-out immersions in 25 degrees and 35 degrees C water
cold immersion fluid ion
2009/7/9
To compare fluid and ion changes during cold (25 degrees C) and thermoneutral head-out immersion (HOI) 9 men were studied under 4 resting conditions lasting 3 h: 2 in 35 degrees C and 2 in 25 degrees ...
Posterior shoulder dislocation and humeral head necrosis in a recreational scuba diver with diabetes
diabetic scuba diver case report injury
2009/7/8
An insulin-dependent diabetic who was previously a recreational scuba diver suffered a posterior shoulder dislocation after a trivial injury and was subsequently found to have local necrosis of the hu...
Subacute effects of inspiratory resistive loading and head-out water immersion on pulmonary function
carbon monoxide pulmonary immersion
2009/6/8
Extrathoracic airways obstruction and scuba diving may induce pulmonary edema, probably because of increased hydrostatic transmural capillary pressure in the lung. This study was designed to examine t...
Effects of non-weight bearing and hyperbaric oxygen therapy in vascular deprivation-induced osteonecrosis of the rat femoral head
osteonecrosis hyperbaric rat animal
2009/6/5
We examined the role of hyperbaric oxygenation (HBO2) combined with non-weight bearing (NWB) in the treatment of vascular deprivation-induced osteonecrosis of the femoral head in the rat. Group 1 incl...

Negative pressure oxygen breathing and head-down tilt increase nitrogen elimination
hyperbaric Human Negative pressure breathing nitrogen elimination cardiac output venous return head down tilt Hyperoxia physiopathology hyperoxia prebreathing decompression
2009/6/2
Negative pressure breathing (NPB) increases the rate of nitrogen elimination, which is thought to be due to an increase in cardiac output due to augmented venous return to the heart. Hyperoxia, howeve...
