Lower Respiratory system: Speech (larynx) Gas exchange. Maintenance of pH. The respiratory system and renal system are very important in regulating the pH. Bicarbonate and carbonic anhydrase. Gas Exchange 1. Pulmonary ventilation—inflow and outflow of air between the atmosphere and the lung alveoli 1. how far from memphis to oklahoma cityWeblated using the alveolar gas equation: PAO 2 = FIO 2 (barometric pressure – water vapor pressure) - PACO 2/RQ.24 Where: alveolar carbon dioxide tension (PACO 2) is substituted with PaCO 2 and respiratory quotient (RQ) is taken as 0.8. Oxygen delivery (DO 2) was calculated as CaO 2 X Q t. Venous admixture (Q s/Q t) was calculated using hierarchy sortingWebDue to a decline in inspired oxygen pressure at high altitudes, the driving pressure for the gas exchange in alveoli also reduces .
