Estimation of Perioperative Atelectasis

Status Completed

Clinical Trial Summary

This study will compare an oxygenation test based on arterial blood gas analysis with computed tomography for estimating the extent of atelectasis.

Clinical Trial Description

Computed tomography of the lungs is the gold standard for investigating the extent of atelectasis, which is common in the perioperative setting. Atelectasis increase the risk of postoperative pulmonary complications and result in pulmonary shunt, which is one of the two major causes of impaired oxygenation. The other cause is admixture of venous blood from poorly ventilated regions of the lungs. The investigators have developed an oxygenation test utilizing arterial blood gas analysis at different inspired fractions of oxygen, which may be used to distinguish between these two causes. This observational study aims to establish the agreement between computed tomography and the oxygenation test for estimating the extent of atelectasis. ;
