Influence of increased gas density and external resistance on maximum expiratory flow
human respiratory lung pressure
2009/7/17
The effect of external resistance on the relationship of expiratory air flow and intrathoracic and mouth pressure on subjects breathing gas of increased density was investigated. Five subjects breathi...
Increased pulmonary vascular resistance during liquid ventilation
pulmonary liquid ventilation fluorocarbon cat animal
2009/7/16
The effect of liquid ventilation on pulmonary vascular resistance was studied in an isolated cat lung preparation in situ. Lungs were perfused with whole blood from a donor cat at a constant flow of 1...
Physiologically and subjectively acceptable breathing resistance in divers' breathing gear
hyperbaric chamber breathing resistance exercise equipment
2009/7/8
To determine acceptable levels of breathing resistance in divers' gear, 6 subjects were exposed to varying levels of breathing resistance under demanding and realistic conditions. The immersed air-bre...
Effects of hyperbaric oxygen on ventricular performance,pulmonary blood volume,and systemic and pulmonary vascular resistance
pulmonary cardiovascular hyperbaric air
2009/6/8
The cardiovascular effects of hyperbaric (3 atm abs) air, 100% oxygen, and hyperbaric oxygen (HBO2) at 3 atm abs were investigated in 13 pentobarbital-anesthetized dogs. We measured heart rate, arteri...
Effects of inspiratory and expiratory resistance in divers' breathing apparatus
CO2 carbon dioxide hyperbaric chamber respiratory inspiratory resistance expiratory resistance
2009/6/5
This study was performed to determine if inspiratory breathing resistance causes greater or smaller changes than expiratory resistance. Unacceptable inspiratory resistances were also determined. Five ...
