The normal resting cardiac output: serial determinations by a dye dilution method.
The resting output of the normal heart has been investigated by many workers (Krogh and Lindhard, 1912; Christiansen et al., 1914; Stewart, 1921; Grollman, 1928; Hamilton et al., 1932; Nylin, 1933; Berseus, 1943; McMichael and Sharpey-Shafer, 1944; Cournand et al., 1945; Stead et al., 1945; Werko, 1947; Chapman et al., 1950; Doyle, et al., 1953; Donald et al., 1955; Goodyer et al., 1960; Reeves...
متن کاملSerial 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...
متن کاملThe Construction of Normal Standards for Cardiac Output in Man.
The present method of calculating normal cardiac output standards in man involves a fallacy, and has led in practice to erroneous conclusions (1). This is a serious matter for clinicians, since it has been shown by Starr that the first indications of symptomless heart disease may be given by abnormalities in cardiac output (2). Thus it is reasonable to suppose that in the next few decades the d...
متن کاملNoninvasive Doppler determination of cardiac output in man. Clinical validation.
A noninvasive technique for assessing cardiac output (CO) was evaluated by comparing it with thermodilution determinations in patients in the intensive care unit. The new method uses pulsed ultrasound to measure aortic diameter and continuous-wave Doppler ultrasound to obtain aortic blood velocity. An initial study evaluating just the velocity measurement showed that changes of the Doppler inde...
متن کاملValidity of indicator-dilution determinations of cardiac output in patients with mitral regurgitation.
mHE indicator-dilution method has been widely employed for determination of cardiac output since its introduction by Stewart' and Hamilton and associates.2 The effect of unrecognized recirculation of indicator particles upon the primary indicator time-concentration curve has caused concern as to whether this method may be employed in such conditions as mitral regurgitation3' 4and as to whether ...
