Acoustic Analysis of Breath Sounds as a Surrogate for Gas Exchange Thresholds
Acoustic Analysis Breath Sounds Gas Exchange Thresholds
2015/5/21
Respiratory gas exchange threshold measurements are a reference standard for measuring sustainable exercise capacity (McLellan and Skinner, 1981). A recent consensus report suggested that ‘threshold b...
Evolution of Gas Exchange Abnormalities in Patients with Liver Cirrhosis Candidate for Liver Transplantation
Blood gas Cirrhosis Hypoxemia
2015/9/25
Background: Hypoxemia is common in patients with cirrhosis but the natural history of this syndrome is unknown. This study was conducted to evaluate the natural history of arterial oxygenation in pati...
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 ...
Steady-state gas exchange in normothermic,anesthetized,liquid-ventilated dogs
Fluorocarbons liquid ventilated respiration animal dog
2009/7/17
Anesthetized, paralyzed, purebred beagle dogs were ventilated for 45 min (n = 5) and 60 min (n = 5) with oxygenated (PIO2 = 685 mmHg) FC-80 fluorocarbon liquid at 38 degrees C. The PaCO2 remained cons...
Alveolar gas exchange during simulated breath-hold diving to 20 m
CO2 carbon dioxide pulmonary hyperbaric cardiac output breath-hold
2009/6/12
Alveolar gas exchange, as affected by changes in pulmonary blood flow, was studied in five subjects performing breath holds lasting 75 s at the surface and during compression to 20 m in a hyperbaric c...
