动脉氧分压(PaO_2)和肺泡—动脉氧分压差〔P(A-a)O_2〕是监护危重病人常用而又敏感的指标,但由于受吸氧浓度(FiO_2)的影响,临床上难以在FiO_2变化的情况下,对同一患者的气体交
PaO2 and alveolar-arterial pressure difference [P (Aa) O2] are common and sensitive indicators for monitoring critically ill patients. However, due to the influence of oxygen concentration (FiO2) Changes in the case of gas exchange for the same patient
