Purpose:

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.


Study summary:

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).
