Brief Summary

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

The purpose of this study is to test the hypothesis that decreasing the inspired oxygen concentration during thoracic surgery requiring one lung ventilation will improve post-operative oxygenation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

One lung ventilation is frequently required during thoracic surgery and results in decreased lung function post-operatively. Supra-physiologic oxygen levels during surgery may contribute to this decrease in lung function by worsening lung injury intra-operatively.

This study will include patients undergoing surgery to remove a lung lobe requiring one lung ventilation.

The patients will be divided into two groups with the experimental group receiving a 60% oxygen in air mixture and the control group receiving 100% oxygen.

The two groups will be compared by using a measure of lung function (the ratio of the partial pressure of oxygen in arterial blood to the inspired oxygen concentration) and blood levels of a protein correlated with lung injury (receptor of advanced glycation end products RAGE).
