Effect of respiratory changes on the degree of arterial oxygen saturation

Bulletin of Experimental Biology and Medicine Aims and scope

Summary

Acute experiments were performed on rabbits, cats and dogs under urethane anesthesia. The author studied the effect of respiratory changes (pulmonary ventilation, tempo, rhythm, amplitude of respiratory motions) on the degree of arterial blood saturation with oxygen.

As shown by these investigations, the influences provoking the changes of conditions of pulmonary ventilation are associated with the appearance of arterial hypoxia. Insufficient pulmonary aeration may occur when the total level of the pulmonary ventilation is decreased, as well as in irregular ventilation of different portions of the lungs in discoordination of respiratory motions.
