Inspired O2 (PiO2) PiO2 = FiO2 x (barometric pressure - saturated vapour pressure of H20) PiO2 = 0.21 x (760 - 47) - sea level. After obtaining a patients PFT results, they have a VC of 3.4, FRC of 5.8, and an ERV of 1.2. Abstract An oxygen deficiency exists when the concentration of oxygen, by volume, drops to a level at which atmosphere supplying respiratory protection must be provided. Oxygen consumption varied directly with Vt and inversely with compliance, increasing from 4.8 +/- 0.07 L/min with the HC-500 mL Vt model to 6.2 +/- 0.05 L/min Your VO2 at this stage of maximal exertion is called your maximal oxygen consumption ( VO2max ). 25.7 mL/cm H2OD. These calculations are very easy to perform as long as you know the formula. This parameter is crucial in terms of any endurance sport and allows you to train effectively as well as properly.
