Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

. The aim of this study, thus, is to evaluate shunt fraction and markers of alveolar distress during one lung ventilation (OLV) at different levels of positive end expiratory pressure (PEEP). Moreover, investigators will focus on predicting factors of high shunt levels during OLV.
