V A (ml/min) x P A CO 2 (mmHg) = VCO 2 (ml/min) x K where P A CO 2 is partial pressure of CO 2 in alveoli; K is barometric pressure. p a CO 2 – arterial partial pressure of carbon dioxide during the alveolar exchange; RQ – respiratory exchange ratio or the respiratory quotient, meaning the ratio between pO 2 and pCO 2; And the resultant is p A O 2 which is the partial pressure of alveolar oxygen also written as pO 2. The AGE formula is: if this applies. then AGE can be simplified as: Alveolar oxygen is used in calculating the alveolar-arterial (A-a) gradient of oxygen and the amount of right-to-left cardiac shunt. The alveolar oxygen equation is: p A O 2 = F I O 2 x (P ATM – P H2O) – (p a CO 2 / RQ) Jump to: 1.

b) Increase the partial pressure of oxygen in the alveoli. The alveolar ventilation equation describes the exact relation between alveolar ventilation and P A CO 2 for any given metabolic rate (VCO 2). V A (ml/min) x P A CO 2 (mmHg) = VCO 2 (ml/min) x K where P A CO 2 is partial pressure of CO 2 in alveoli; K is barometric pressure.

The alveolar PO2 can be calculated by using the alveolar air equation: PAO 2 = P I O 2 - + F Alveolar minute ventilation is less than minute ventilation and is calculated as ([tidal volume − dead space] × respiratory rate) or ([500 mL − 150 mL] × 12 breaths/min) = 4200 mL/min. Increasing tidal volume increases alveolar ventilation more effectively than does increasing respiratory rate (see the earlier discussion of restrictive and obstructive disease). Alveolar Ventilation rate (V'A), measured in ml/min, is the rate of air flow that the gas exchange areas of the lung encounter during normal breathing.
