WebNov 25, 2024 · Thermodilution (TD) and indirect Fick (IF) methods are widely used to measure cardiac output (CO). They are often used interchangeably to make critical clinical decisions, yet few studies have compared these approaches concerning agreement and comparative prognostic value as applied in medical practice. WebSep 2, 2024 · The Fick principle requires an indicator that is added at a constant rate. One of the better indicator substances is O 2 because both the rate of oxygen uptake by the lung and the amount of O 2 on either side of the lung can be measured fairly easily. The specific formula for CO using O 2 as the indicator is:
