WebFick equation [4] The Fick equation states that VO2 is equal to the product of cardiac output ( Q) and the difference between arterial and venous oxygen content at the level of the capillary (a-vO2diff). VO2 max= Q * (C a O2 - C v O2) These values are obtained during exertion at maximal effort. Q= cardiac output of the heart, C a O2- arterial ... WebCardiac Output Calculator.

At this diameter, the resistance of the cornea to flattening is counterbalanced by the capillary attraction of the tear film meniscus for the tonometer head. The IOP (in mm Hg) equals the flattening force (in grams) multiplied by 10. 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: carbeth hutters for sale
