The alveolar gas equation is the method for calculating partial pressure of alveolar oxygen (PAO2). The equation is used in assessing if the lungs are properly transferring oxygen into the blood. The alveolar air equation is not widely used in clinical medicine, probably because of the complicated appearance of its classic forms.The partial pressure of oxygen (pO2) in the pulmonary alveoli is required to calculate both the alveolar-arterial gradient of oxygen and the amount of right-to-left cardiac shunt, which are both clinically useful quantities. However, it is not practical to take a sample of gas from the alveoli in order to directly measure the partial pressure of oxygen. The alveolar gas equation allows the calculation of the alveolar partial pressure of oxygen from data that is pra

| - Die Alveoläre Gasgleichung erlaubt es, den Sauerstoffpartialdruck in den Alveolen der Lunge (pAO2) zu errechnen. Dieser wiederum ist erforderlich für die Berechnung der Alveolo-arteriellen Sauerstoffdruckdifferenz oder der Größe des Rechts-Links-Shunts, beides klinisch interessante Maßzahlen. Da man keine Gasproben aus den Alveolen entnehmen kann, um den Sauerstoffpartialdruck direkt zu messen, muss man ihn indirekt errechnen. Erstmals beschrieben wurde diese Art der Berechnung 1946. (de)
- 肺胞気式 (alveolar gas equation)とは、肺胞の酸素の分圧（PAO2）を計算する方法である。この式は、肺が適切に酸素を血液に取り込んでいるかどうかを評価する際に用いられる。 肺胞における酸素の分圧（pO2）は，酸素のと、を計算するのに必要であり，これらはいずれも臨床的に有用な量である．しかし，酸素分圧を直接測定するために，肺胞からガスを採取することは現実的ではない。肺胞気式は、実際に測定可能なデータから酸素の肺胞分圧を計算することができる。この方程式は1946年に初めて特徴づけられた。 (ja)
