Brief Summary

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

To observe the effect of different fresh flows (1 L / min and 4 L / min) on the carboxyhemoglobin level non-invasively and continuous measurement and to determine the contribution of smoking to the intraoperative carbon monoxide accumulation.
