WebSimultaneously measured cardiac output obtained by thermodilution (TD), transcutaneous suprasternal ultrasonic Doppler (DOP), CO2-rebreathing (CR) and the direct Fick method (FI) were compared in eleven healthy subjects in a supine position (SU), a sitting position (SI), and during sitting exercise at a workload of 50 W (EX). WebThe average of each series of 50 measurements showed excellent correlation with the estimates of cardiac output based on the direct Fick method for oxygen. The maximum difference between the values of cardiac output randomly measured by the thermodilution method was 40% for the left side of the heart and 70% for the right side.

WebThis involves the calculation of oxygen content in arteries and veins through haemoglobin levels in the red blood cells and its oxygen saturation. Cardiac Output = (125 ml O 2 /min/m 2 * BSA) / [13 * Hb * (SaO 2 - SvO 2 )] = O 2 consumption / Arteriovenous O 2 difference. While BSA is calculated through the following equation: Body Surface Area ... WebBackground: Cardiac output (CO) is a prognostic factor in pulmonary hypertension (PH). Right heart catheterisation using the direct Fick method or thermodilution (TD) is the reference technique for CO measurement. Impedance cardiography (IPc) is a known non-invasive method of measuring CO.
