Regulation of Cardiac Output [PDF]
Anesthesiology, 1967 MOST physicians are surprised to learn that the heart has relatively little effect on the normal regulation of cardiac output, but all the physician has to do is to look at his patients, and he will see that this is true. He will see a patient with mitral valvular disease whose heart has a maximum pumping ability no greater than one third normal, but ...

Critical care nurses frequently are involved in obtaining cardiac output measurements and in using these data to assess and to plan therapy. This article reviews the physiologic determinants of cardiac output and the clinical factors that influence these determinants.

Current Opinion in Anaesthesiology, 2009
The primary goal of hemodynamic therapy is the prevention of inadequate tissue perfusion and inadequate oxygenation. Advanced cardiovascular monitoring is a prerequisite to optimize hemodynamic treatment in critically ill patients prone to cardiocirculatory failure. The most ideal cardiac output (CO) monitor should be reliable, continuous, noninvasive,

Portapres® derives continuous estimates of cardiac output from the peripheral pulse and has the potential to be an extremely valuable physiological and clinical tool. We assessed Portapres® estimates of cardiac output in healthy subjects at rest, during maximal treadmill exercise (n=8) and during decreases caused by orthostatic stress (n=8). Comparison

THE determination of cardiac output by the dye dilution techniques requires the taking of serial arterial blood samples at short regular intervals. Direct puncture of the brachial artery of cattle1 enables such samples to be collected. T.1824 (Evans blue) was injected into the jugular vein of the subjects at a dose of approximately 0.40 mgm./kgm.

Cardiac Output by Thermodilution
JAMA: The Journal of the American Medical Association, 1985To the Editor.— It has been estimated that between 1 and 2 million pulmonary artery catheters were inserted for hemodynamic monitoring in the last decade. 1 The prevalence of the procedure has increased substantially over the past few years. It is therefore of interest that the methodology of a clinical hemodynamic measurement, cardiac output by ...

IN a previous communication we described the determination of the cardiac output in cattle by an injection method using T.1824 as the intravascular indicator1. The same method was used to determine the cardiac output in horses. The technique used for obtaining arterial blood samples from the brachial artery of horses was that described by Fisher2, and ...

Continuous Fick cardiac output compared to thermodilution cardiac output
Critical Care Medicine, 1986A system has been developed to monitor continuously the components of the oxygen Fick equation: oxygen consumption by a gas exchange analyzer and arteriovenous oxygen difference by pulse and fiberoptic oximetry. A computer-based system was developed which calculates cardiac output and other variables every 20 sec.

Current Opinion in Anaesthesiology, 1996
Cardiac output monitoring has provided a theoretical basis for detemining how to provide safer haemodynamic support. The current debate focuses on the methodological means of proving that cardiac output monitoring is beneficial and on the comparative advantages, side effects, availability and cost ...
