WebApr 2, 2024 · The alveolar ventilation equation is obtained by substituting Paco2 for Faco2 and rearranging the Fick equation: Va = (V co2/Paco2 )K, where K is a constant (= 0.863) to convert Fco2 to Pco2 in mm Hg, and Vco2 in mLsTPD/min to Va in LBTPs/min. In practice, arterial Pco2 is substituted for alveolar Pco2 because the two values are equal in normal ... WebThe PaO2 decreases (and the P(A-a)O2 increases) as the work of breathing increases, and when it becomes excessive (and/or the FEV1 falls below 20% to 25%), the PaCO2 begins to increase. Therefore, in any patient with asthma, a decreasing PaO2 and an increasing PaCO2, even into the normal range, indicates severe airway obstruction that is ...
