Pressor Effect of Hypertonic Saline on Pulmonary Circulation
It has been suggested that the pressor effect of hypertonic solutions of sodium chloride on the Pulmonary circulation results from spasm of the pulmonary veins at their junction with the left atrium. These studies demonstrate that the increased resistance in the pulmonary vessels develops upstream to this site and that it may result primarily from mechanical blockage of vessels by clumped erythrocytes rather than from vasoconstriction.
