In this post, I aim to explore the the sensitivity of cardiac output estimation to oxygen consumption, body surface area, hemoglobin concentration and arteriovenous oxygen difference.
The oxygen consumption is in mL/min. The hemoglobin is in g/L. The arteriovenous oxygen difference is difference in fractional saturation.
The vertical line is a hemoglobin of 150 g/L. The red line is a cardiac index of 2.8 L/(min m2)
See Thermodilution for some considerations with respect to Thermodilution assessment of cardiac output and an animated gif (this was made to prior to the capacity to embed CDF's. If time permits I will convert and embed).
