Fick equation (cardiac output formula) The most common formula used for determining the cardiac output is the Fick equation. It states that: CO=VO2 / (Ca−Cv)CO=VO2 / (Ca−Cv) where: VO2VO2 stands for the oxygen consumption of pure gaseous oxygen (in mL/minute); CaCa is the co...
Direct Fick methodExerciseWe used the direct Fick measurements to validate a method for estimating cardiac output by iteratively fitting [Formula: see text] at the mouth to lung model values. This model was run using a series of 50, 30 and 10 breaths to test sensitivity to number of breaths...
Three common formulae were used to calculate iFick for comparison - Lafarge, Dehmer, and Bergstra. Thermodilution was measured in triplicate and averaged with removal of outliers. Correlation between each method and direct Fick was assessed with linear regression. Bias between each method and direct...
Cardiac output (CO) measurements employing the direct Fick principle represent the gold standard in right-sided heart catheterization (RHC). The current widespread approach in hemodynamic workup however uses the indirect Fick principle with assumed values for oxygen uptake (VO2) leading to incorrect C...

A Cardiac Output Monitor is a device used in neonatal intensive care to measure the amount of blood pumped by the heart per minute, helping clinicians assess the newborn's hemodynamic status and oxygen delivery. AI generated definition based on: Hemodynamics and Cardiology (Third Edition), 2019 ...
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...
