Fick versus thermodilution
WebAug 1, 2024 · The thermodilution (TD) method is routinely used for the estimation of cardiac output (Q̇ C).However, its accuracy, compared with the gold-standard Fick method, where systemic oxygen uptake (V̇O 2) is directly measured, and Q̇ C calculated from V̇O 2 and the arterio-venous oxygen difference (“direct” Fick), has not been well validated. The … WebJan 20, 2024 · Thermodilution measurements have numerous potential sources of error Under laboratory conditions, the agreement between this method and the direct Fick method is within a margin of 25%.

Fick versus thermodilution
Did you know?
WebFick Method (FM) and the Thermodilution method (TD) [11]. Several studies have compared different technologies to measure CO, but only a few studies have tried to answer whether the FM or TD is better in patients with PAH [12]. Recent studies show that there are significant discrepancies between the CO measured by FM or TD [13,14]. We have WebJul 13, 2015 · van Grondelle et al (1983) found that cardiac output values less than 2.5L/min (i.e. a cardiac index of around 1.2-1.3) were associated with a big difference between the Fick and the thermodilution method (up to 35%). Of course, one might argue that this would be completely meaningless clinically, as you would still end up with a cardiac index ...
Web9.6K views 2 years ago In this video we will discuss cardiac output and the FICK equation. We will begin by discussing cardiac output both as a concept and as an equation related to heart rate... WebFeb 1, 2024 · Fick or thermodilution methods are routinely used in cardiac catheterization laboratories or the intensive care setting for hemodynamic evaluation. Although precise CO measurement using the Fick formula requires measurement of the true oxygen consumption, the majority of centers use estimated rather than measured oxygen …
WebAccordingly, peak exercise CO values were significantly lower when measured by thermodilution versus direct Fick (9.0 ± 3.9 L/min versus 11.33 ± 4.3 L/min, P < 0.001). Bland–Altman analysis comparing TDCO to DFCO revealed a significant overall negative bias of −1.81 L/min with TDCO, with unacceptably broad limits of agreement (Fig. 1b ). WebApr 26, 2007 · Since thermodilution measures right ventricular output and disregards the bronchial circulation compared with NICOM, we considered that a 20% bias and precision was acceptable. Although unacceptable results were infrequent, it is obvious that several factors increased their number artificially.
