The Air Test: A New Simple, Non-invasive Method to Diagnose Anesthesia-induced Atelectasis

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.

Treatment and study plan

Air Test

Procedure

The Air Test simply consisted in breathing room air for 5 min on arrival into the postoperative anesthesia care unit while measuring peripheral oxygen saturation by Pulse oximetry

Primary outcomes

Presence of postoperative atelectasis meassured by SpO2 levels and confirmed by computed tomography.

Time frame: 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.
