Cardiac Output by Thermodilution

JAMA: The Journal of the American Medical Association, 1985
To 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 ...

Continuous Fick cardiac output compared to thermodilution cardiac output

Critical Care Medicine, 1986
A 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.

Cardiac output monitoring

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 ...

Cardiac vibrational intensity and cardiac output

American Heart Journal, 1948
1. 1. An electronic heart sound meter has been devised to convert the complex pattern of low-frequency cardiac vibrations picked up at the chest wall into a simple “resultant frequency.” 2. 2. The “resultant frequency” varies during each heart cycle in a manner similar to the ventricular volume curve. 3. 3.

Cardiac Output in Anencephalic Fetuses

Gynecologic and Obstetric Investigation, 1991
The cardiac output was measured by means of Doppler echocardiography in four anencephalic fetuses during the late second or third trimester of pregnancy. Anencephalic fetuses showed a higher dominance of right ventricular output when compared to healthy fetuses, suggesting that the relationship between brain mass and body weight affects the ...

Cardiac output measurement

2005
Abstract Use of a pulmonary artery catheter and cardiac output measurement Pulmonary artery catheter pressure (mm Hg)A catheter passed into the right atrium from an easily accessible central vein can be passed through the right ventricle and out into the pulmonary arterial tree while the vascular waveforms are visualized.

High cardiac output by a continuous cardiac output pulmonary artery catheter

Journal of Cardiothoracic and Vascular Anesthesia, 2002
A 60-YEAR-OLD man with an orthotopic heart transplantation 7 months previously for congestive cardiomyopathy developed histologically proven acute transplant rejection and was admitted to the intensive care unit. Initially, he was hemodynamically stable while receiving dobutamine and nitroglycerin.

Cardiac output during labor

American Journal of Obstetrics and Gynecology, 1956
Abstract 1. 1. In a study of 47 patients by a modified pulse pressure method, changes in cardiac output were recorded during late pregnancy, in labor, and in the early puerperium. This is the first report on cardiac output in labor. 2. 2. During effective contractions in labor, the cardiac output rises an average of 30.9 per cent over the ...

The effect of PEEP on cardiac output.

CHEST Journal, 1983
sitive end-expiratory pressure ventilation (PEEP) is well established as an integral part ofthe management of patients with the adult respiratory distress syndrome. While PEEP improves pulmonary gas exchange in the majority of patients, it may also decrease cardiac output.’5 As a result, oxygen transport (cardiac output x arterial oxygen content) may ...
