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 ... WebImages. Cardiac Output.

In the Td technique, cold saline of a known volume and temperature is injected … WebThe blood concentration of oxygen is expressed as mL O 2 /ml blood, and the VO 2 is expressed in units of mL O 2 /min. If CaO 2 and CvO 2 are 0.2 mL and 0.15 mL O 2 /ml blood, respectively, and VO 2 is 250 mL O 2 /minute, then CO = 5000 mL/min, or 5 L/min. Ventricular stroke volume would be the cardiac output divided by the heart rate. twists for men short hair
