Surgeries Undergoing General Anesthesia
Conditions
Brief summary
This is a prospective study that will record the Pulse Pressure Variability (PPV) from the arterial line and Plethysmography Variability Index (PVI) from the pulse oximeter while the patient is in the supine position and then again in the prone position. There will be no change in anesthetic care based on the study protocol. The primary objective of this study is to evaluate the changes in PVI and PPV when changing from the supine and prone position in pediatric-aged patients.
