This is a prospective, observational study. This study will assess the effect of temporary changes in body position (supine, head of bed elevated 30 degrees, head of bed elevated 60 degrees) in anesthetized patients. Tissue oxygenation will be assessed non-invasively using near infrared spectroscopy (NIRS) by a device that is used in our operating rooms and the ICU setting to assess cerebral and tissue oxygenation.
