WebAug 22, 2024 · National Center for Biotechnology Information WebSep 30, 2024 · So the partial pressure of oxygen in the alveoli (P A O 2) is determined by the partial pressure of oxygen in inhaled gas, minus water vapor pressure, minus the concentration of carbon dioxide evolved into the alveoli from mixed venous blood returning to the lungs. This is expressed in the alveolar air equation. Figure 5. WebOver multiple breathing cycles, the gas mixture contained within the cylinder of the lung simulator will approach some steady-state concentration, X O2,c. To derive the equation for X O2,c, it was noted that in this steady state the volume of oxygen entering the lung simulator, V O2,I, must be equal to the volume of oxygen that exits, V O2,E ... gotham knights music
