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 ...

Assessment of trending ability of cardiac output monitors by polar plot methodology.

Journal of Cardiothoracic and Vascular Anesthesia, 2011
OBJECTIVES To develop a valid statistical method of showing acceptable cardiac output (CO) trending ability when new CO monitors are compared to a reference standard, such as thermodilution, using polar coordinates.

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 ...

Cardiac output measurement

Anaesthesia & Intensive Care Medicine, 2013
Abstract Optimization of fluid status, perfusion pressure and cardiac output in intraoperative and critical care settings improves clinical outcomes. Cardiac output is a measure of the blood pumped around the circulation. Modelling of the circulation facilitates estimation of cardiac output from readily measured variables.
