Brief Summary

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

One-lung ventilation interrupts oxygenation. The effect of heated humidifed breathing circuit on arterial oxygenation during one-lung ventilation has not been investigated. The investigators will investigate the effect of the heated humidifed breathing circuit on oxygenation during one-lung ventilation in patients undergoing thoracoscopic surgery.
