O 2 肺胞気式の近似式として、P A O 2 =150－PaCO 2 /0.8と書ける。 P A O 2 を横軸、P A CO 2 を縦軸にとったO 2 、CO 2 ダイアグラムにおいて、O 2 肺胞気式の近似式を変形したガスRQ ラインとフィックFickの式を変形した血液 RQラインの交点から理想肺胞気の組成が求められる。

肺胞の空気をどのように計算しますか？

肺胞気式は、肺胞内の酸素分圧（PAO2）を概算するために使用される式です。. PAO2=（PB-PH2O）FiO2-（PaCO2÷R）ここで、PBは気圧、PH2Oは水蒸気圧（通常47mmHg）、FiO2は吸気酸素の分圧であり、Rはガス交換率です。. これを考慮して、肺胞換気量をどのように計算し ...
