WebThe direct oxygen Fick approach is the standard reference technique for cardiac output measurement. It probably is the most accurate method currently available, although … WebSeveral invasive and noninvasive techniques have been in- troduced to measure cardiac output in humans. The “gold standard” is the direct Fick method in which the cardiac out- put is calculated as the quotient of oxygen uptake ( O2 ) and the difference of the arterial and mixed venous oxygen con- tent. WebThe arterial and venous oxygen content (or saturation) is estimated though hemoglobin levels (obtained from blood test) Therefore, the Fick based estimation becomes: Cardiac Output = O2 consumption / Arteriovenous O2 difference = (125 ml O2/min/m2 x BSA) / [13 x Hb x (SaO2 - SvO2)] Where BSA is calculated through Haycock’s formula: Body ... thetford aqua rinse plus data sheet
