Brief Summary

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

Respiratory complications represent the second most frequent type of postoperative complications with an incidence estimated to range from 2.0% to 7.9%

It has been shown that intra-operative protective ventilation is associated with a reduced risk of respiratory complications. The effects of intra-operative inspiratory oxygen fraction (FiO2) remain to be investigated.

In this study, the investigators aim to investigate the association between intra-operative FiO2 and respiratory complication as well as surgical site infection and ICU admission in patients undergoing non-cardiothoracic surgery. The investigators primary hypothesis is that high intra-operative FiO2 increases the risk of postoperative respiratory complications independent of predefined risk factors.
