THE PULMONARY BLOOD VOLUME IN MAN*

Acute effects of increase in pulmonary vascular distending pressures on pulmonary blood volume and pulmonary extravascular fluid volume in man.

The acute hemodynamic effects of supine leg exercise or atrial pacing were studied in 114 patients undergoing right and either transseptal (87 cases) or retrograde (27 cases) left heart catheterization. Seventy-one patients - 15 with coronary artery disease, 22 with aortic valve disease, and 34 with mitral valve disease - performed exercise on a bicylce ergometer. Forty-three patients, of whom ...

Pulmonary Blood Volume and Pulmonary Capillary Blood Volume in Valvular

Measurements of pulmonary blood volume (PBV) and pulmonary capillary blood volume (V,) and hemodynamic studies were made in a series of 106 patients with valvular heart disease (62 with predominant mitral lesions and 44 with predominant aortic lesions). The results were compared with the data obtained from 14 "normal" patients and nine normal subjects. In 14 "normal" patients, the PBV varied fr...

Pulmonary arterial blood volume and tissue volume in man and dog.

After the injection of an ethyl ether-alcohol solution above the pulmonic valve, the pulmonary arterial circulation time was determined in conscious man by an established body plethysmographic technique and in anesthetized man by a newly developed pneumotachographic method. In the anesthetized dog, estimates of pulmonary arterial circulation time determined by this new method were compared with...
