Intraoperative Air-Test

October 1, 2018 updated by: Carlos Ferrando, Fundación para la Investigación del Hospital Clínico de Valencia

Incidence of Intraoperative Positive Air-Test

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.
