Thermodilution vs. Fick Method for Estimating Cardiac Output

WebUsing a differential Fick equation, the partial carbon dioxide rebreathing technique calculates CO from the change in carbon dioxide production (V̇co 2) and the change in end-tidal carbon dioxide pressure (Petco 2) when periodic partial carbon dioxide rebreathing creates a carbon dioxide disturbance. 2 Therefore, the accuracy of the technique … Web20 mrt. 2024 · The mean CO measured by the thermodilution method was 4.94 ± 1.17 L/min and the mean CO measured by the indirect Fick method was 5.82 ± 1.97 L/min.

WebCardiac output (Qt) and related variables can be calculated on a continual basis through the Fick principle by using an indirect calorimeter to measure V ˙ O 2 ( V ˙ o 2A) and dual oximetry to measure mixed venous oxygen saturation (S V ¯ o 2) and arterial oxygen saturation (SpO 2 ). WebFick calculations systematically underestimate gas exchange measurements. The Fick method is inaccurate and unreliable when an estimation of VO 2 is required in patients with this hemodynamic pattern. (Crit Care Med 1998; 26:1200-1207) © Williams & Wilkins 1998.
