Cardiac function curves in conscious dogs

open access: closedAmerican Journal of Physiology-Legacy Content, 1964
Repeated ventricular function curves were determined over a period of several weeks in seven conscious dogs. The atrial pressures were raised by infusing Tyrode's solution through a large catheter chronically implanted in the left jugular vein while recording systemic arterial pressure, right and left atrial pressures, heart rate, and ventricular ...

Noninvasive Measurement of Cardiac Function during Exercise, Using Resaturation Curves

open access: closedChest, 1976
The resaturation curve, a noninvasive indicator-dilution test using an ear oximeter to detect rates of change in arterial oxygen saturation during breathing of various concentrations of oxygen, was used to assess cardiac performance in normal subjects and in 108 patients with cardiac valvular disease. Measurements made during exercise included the time

Changes in canine cardiac function and venous return curves by the carotid baroreflex

open access: closedAmerican Journal of Physiology-Heart and Circulatory Physiology, 1986
Venous return curves and cardiac function relationships were simultaneously determined in 10 pentobarbital-anesthetized dogs at three different isolated carotid sinus pressures. Changing carotid sinus pressure (CSP) between 50 and 200 mmHg produced large changes in the zero flow intercept of the venous return curves from 15.37 +/- 0.97 to 11.94 +/- 1 ...
