To the Editor: In their review of the acute respiratory distress syndrome (ARDS) (Aug. 10 issue),1 Thompson et al. recommend that patients be placed in the prone position when the ratio of the partial pressure of arterial oxygen to the fraction of inspired oxygen (Pao2:Fio2) is less than 120 mm Hg. However, the guidelines for the mechanical ventilation of patients with ARDS2 recommend this strategy for patients with severe ARDS, which the guidelines define as a Pao2:Fio2 of less than 100 mm Hg. Furthermore, one of the inclusion criteria for a trial that showed a decrease in mortality with this . . .

急性呼吸窘迫综合征

致编辑：在他们对急性呼吸窘迫综合征 (ARDS) 的评论（8 月 10 日）中，1 Thompson 等人。建议当动脉氧分压与吸入氧分数（Pao2:Fio2）的比值小于 120 mm Hg 时，将患者置于俯卧位。然而，ARDS2 患者的机械通气指南建议重度 ARDS 患者采用这种策略，指南将其定义为 Pao2:Fio2 小于 100 mm Hg。此外，一项试验的纳入标准显示死亡率降低。. .
