By regression analysis the following formula was obtained showing the relation (r=0.919, P<0.0001, r=0.85): Cardiac index by Fick method =-0.63+1.03 (cardiac index by echo). Although the mean CO by echocardiography was not the same as that by the Fick method, it is possible to predict ...
Cardiac index by FloTrac was higher than cardiac index by Fick (6.4±3.4 vs 3.7±1.2 L/min/m 2 , P<.001). Bland-Altman analysis showed a consistent overestimation of cardiac index by FloTrac which worsened as cardiac index increased (mean bias 2.7 L/min/m 2 , 95% limits of ...

73,89 The cardiac index is higher in foals (2 hours and 2 weeks) and ranges between 150 and 220 ml/kg/min.79 Cardiac output in the horse traditionally has been determined by indicator dilution (thermodilution; indocyanine green dye; lithium) techniques and the Fick method.53,89,90–95 ...
"Cardiac Output Calculator: Fick Equation" is designed to calculate cardiac output, cardiac index, stroke volume, and stroke volume index. Cardiac output is the…
An FiO2 >0.3 is likely to result in oxygen being dissolved in the blood, which should be taken into account in the Fick calculations by measuring PaO2. Even though it is recommended that PaO2 is measured in such cases, it is recognized that the above formula gives a low relative importance...

At present several techniques are used to measure CO. There exist both direct and indirect methods. Direct methods of monitoring CO include the Indicator-Dilution method. The Indicator Dilution method covers a range of techniques such as: thermodilution, Fick and dye dilution. These techniques genera...
Cardiac output was calculated by indirect Fick method and estimated VO2 values were calculated by LaFarge equation: males, VO2 (mL/min/m2) = [138.1 − (11.49 × logeage) + (0.378 × HR)] × BSA; females, VO2 (mL/min/m2) = [138.1 − (17.04 × logeage) + (0.378 × HR)] ...
Objective The aim of this study was to find whether estimated values of Sv O 2 can estimate with accuracy cardiac index using Fick method in comparison with thermodilution in critically ill patients. Material and methods Sixty-one critically ill patients were catheterized (Opticath PA Catheter P...
