Studies of Cardiopulmonary Blood Volume

Cardiopulmonary blood volume in borderline hypertension.

1. A haemodynamic study which included estimation of cardiopulmonary blood volume (CPBV), total blood volume (TBV) and vascular reactivity to noradrenaline was performed in seventeen borderline and sixteen permanent hypertensive patients. 2. Borderline hypertensive patients had higher values of cardiac index, stroke index and heart rate when compared with the permanent hypertensive patients, an...

Blood volume studies in healthy children.

Among the earliest recorded experiments on the tion of the blood volume are those of Bischoff (1856, 1858) and Weicker (1858), who by exsanguinationm directly the amount of blood obtained from the bodies of executed criminals. Since that time much genuity has been xrcised in devising methods of esimating blood volume which would conbine accuracy with ease of application to the living human subj...

Physiologic Studies during Cardiopulmonary Bypass Eliminating Heparinized Blood.

Processing and transfusion of residual cardiopulmonary bypass volume: effects on haemostasis, complement activation, postoperative blood loss and transfusion volume.

The aim of this prospective randomized study was to compare the effects of the transfusion of unprocessed and cell saver-processed residual cardiopulmonary bypass (CPB) volume on haemostasis, complement activation, postoperative blood loss and transfusion requirements after elective cardiac surgery. Blood samples were taken at eight points in time, perioperatively. Haematological data, includin...

Serial Cardiac Output and Blood Volume Studies Following Cardiac Valve

DETERMINATION of the cardiac output during the early postoperative period following open heart surgery has been difficult due to technical problems in adapting the Fick and indicator-dilution methods to the bedside. The recent availability of a radioisotopedilution method using precordial detection provides a simple and reliable means of measuring blood flow in the postoperative setting. In add...
