Abstract
The effect of 15-min inhalation of 8% hypoxic gas mixture on stroke volume was studied in 17 healthy volunteers. The parameter decreased in all volunteers who endured this exposure to the end. At the beginning of exposure the decrease in stroke volume negatively correlated with HR changes, but this correlation disappeared as hypoxia augmented. Physiological significance of stroke volume decrease during severe hypoxia is discussed.
