Although imaging techniques are the reference standard to diagnose alveolar collapse, in the postoperative period and using the peripheral hemoglobin oxygen saturation (SpO2), a non-invasive simple and accurate test (Air-Test) was recently validated to diagnose alveolar collapse.
The aim of this study is to non-invasively describe the incidence of intraoperative atelectasis with the Air-Test in an unselected surgical population. In addition, we attempt to describe the association between positive Air-Test and the patient´s preoperative or intraoperative variables.
The study included consecutive patients who were scheduled for surgery with general anesthesia and mechanical ventilation
Exclusion Criteria:
The Air Test simply consisted in breathing room air for 5 min during anesthesia while measuring peripheral oxygen saturation by Pulse oximetry
Patients with positive Air-Test
Positive Air-Test defined as SpO2 \< 97% while breathing room air
Time frame: During surgery
Plan to share: No
