Determining the cardiac output using Fick's method, concentrations and rates. Solution in JPG format.

Find the cardiac output of a heart using Fick's method given that the concentration of oxygen in the pulmonary artery is 14mL/100 mL (Cin) and in the vein is 20 mL/100 mL (Cout). Oxygen uptake (U) by the lungs is 300 mL/min. Assume that blood flows at a constant rate Q mL/min (the cardiac output).
