[Erythrocyte lipids and the gas transport function of blood in acute hemorrhage].

Alterations of erythrocyte lipid composition were studied during oxygenation of the cells in rabbit lesser circulation in simultaneous single massive hemorrhage. The state of blood respiratory function was studied in order to evaluate an importance of the erythrocyte membranes transformation occurred in lungs during gas exchange; for this purpose arteriovenous difference in oxygen and coefficient of erythrocyte deoxygenation were evaluated. Increase in content of phosphatidyl serine in erythrocytes during blood arterial transformation was shown to correlate highly with arteriovenous difference in oxygen. Pathophysiological importance of the alterations observed is discussed.
