Web1 mei 2024 · Background: The accurate measurement of cardiac output (CO) is required in patients with pulmonary hypertension (PH).While both the thermodilution (TDCO) and indirect Fick (IFCO) methods are commonly used, there is little data comparing them in patients with PH. Methods: We performed a retrospective analysis of patients evaluated … WebThe Fick principle states that blood flow to an organ can be calculated using a marker substance if the following information is known: Amount of marker substance taken …

Bland-Altman analyses comparing cardiac index (CI) estimated by thermodilution (TDCI) or indirect Fick (IFCI) with the gold standard direct Fick (DFCI). Horizontal lines are shown at the mean difference and limits of agreement (±1.96 SD of the differences). The gold standard DFCI is shown on the x axis in all pan-
WebThe Fick principle, as applied to cardiac output, relies on the recognition that the total uptake of oxygen by the peripheral tissues is equal to the product of the blood flow to the … Web10 jan. 2003 · The advantage of comparing the thermodilution technique with an indirect Fick technique is that the indirect Fick technique measures the average cardiac output over several minutes. Thus, differences between measures will better reflect either direct measurement error or measurement of different actual variations.
WebThe Fick principle, as applied to cardiac output, relies on the recognition that the total uptake of oxygen by the peripheral tissues is equal to the product of the blood flow to the peripheral tissues and the arterial-venous oxygen concentration difference. Cardiac output is therefore calculated using the formula:
