An observational study to check whether diffrernce in the carbon dioxide exhaled from two lungs can predict intraoperative fall in blood oxygen levels during elective thoracic surgeries.

A prospective, observational study to evaluate the usefulness of gradient of end tidal carbon dioxide between two lungs in supine and lateral position, to predict intraoperative hypoxemia during one lung ventilation, in elective thoracic surgeries.
