简要总结
Anesthesia-induced atelectasis persist in the postoperative period but are not usually diagnosed because imaging techniques are required. The aim of the study is to determine whether the value of SpO2≤96 while breathing room air (0.21 FiO2) for 5 min, maneuver that we defined as the Air Test, was able to diagnose atelectasis in the postoperative period after a general anesthesia.

结局指标
主要结局
Presence of postoperative atelectasis meassured by SpO2 levels and confirmed by computed tomography.
时间窗: 35 minutes post-surgery
After arrival to the post-surgery unit, patients received supplemental oxygen through a venturi mask with flow adjusted to approximate a FiO2 of 0.5 during the first 30 minutes. The SpO2 measure was made removing the oxygen mask and leaving the patients to breath room air for at least for 5 minutes.
