Intraoperative Air-Test

Completed

• Conditions: Patients With ASA Status I-III Scheduled for Surgery

• Registration Number: NCT03469648
• Lead Sponsor: Fundación para la Investigación del Hospital Clínico de Valencia

Brief Summary

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.
