Pulmonary Blood Volume

A method for continuous recording of pulmonary blood volume in the intact animal has been devised, utilizing the detection of I131-tagged blood from a circumscribed portion of lung field. To rule out the interference of blood in the chest wall the counts per minute (cpm) obtained from the chest wall after removing the lung at the end of the experiment were subtracted from the recorded cpm throughout the experiment. The cpm from the chest wall were found to be stable, so that it was concluded that changes in total cpm were caused by changes in pulmonary blood volume. Constriction of the ascending aorta or pulmonary artery by previously placed loops of plastic tubing produced either right or left heart failure. When left heart failure was produced acutely, the pulmonary blood volume increased an average of 79.5%±6.1 S.E. in 23 dogs. Constriction of the pulmonary artery, producing acute right heart failure, decreased the pulmonary blood volume an average of 38%±2.3 S.E. in 23 dogs.

External Monitoring

A semiquantitative technique for assaying shifts in intrapulmonary blood volume is described. The method consists of the external monitoring of radioactivity over the anterior thorax after the intravenous administration of radioactive iodinated albumin utilizing a sensitive scintillation counter with a focusing collimator attachment. While this method does not yield the quantitative data of the indicator dilution and body plethysmographic techniques, it offers the advantage of confining observations to the intrapulmonary rather than the intrathoracic blood volume. Employing this technique, the effects of the upright posture, peripheral venous pooling and the Valsalva maneuver have been studied. A fall in estimated pulmonary blood volume was noted with each procedure, averaging 28%, 9% and 11%, respectively, below control levels. Submitted on January 16, 1959
