Cardiac output determination after cardiac operation

Non-invasive cardiac output determination by two-dimensional independent Doppler during and after cardiac surgery.

PURPOSE This study was to compare noninvasive measurement of cardiac output (CO) using a novel Doppler technique with invasive CO measurements in the postcardiac surgical intensive care unit. DESCRIPTION Thirty-six patients (67.2 +/- 10 years, New York Heart Association functional class 3.1 +/- 0.3) undergoing coronary revascularization were prospectively examined postoperatively. One hundred...

Determination of cardiac output in the mouse.

A technique is described for determination of cardiac output in the mouse. The method is basically a tracer dilution technique using 86-rubidium as soluble indicator, where a microsampler is used for blood collection and in which the gamma function fitting is applied for area determination.

Determination of cardiac output by Doppler echocardiography.

Cardiac output determined by Doppler echocardiography was compared with that determined by thermodilution at rest and during dobutamine infusion in 10 patients (group A) and by the Fick method at rest in 11 patients (group B). All patients had angina pectoris without valvular heart disease. Maximum spatial blood velocity and cross sectional aortic area were estimated by the Doppler technique an...

Methodology of indicator dilution cardiac output determination.

induced moderate hypothermia for low cardiac output after pediatric cardiac surgery

postoperative low cardiac output states are a major cause of postoperative mortality in infants and children following corrective cardiac surgery or congenital heart defects. whole body hypothermia has been used since 2001 in the management of these low output states when they are refractory to conventional modes of therapy. from december 2001 to april 2006, 25 cases were included in this study...
