Brief Summary
The investigators' goal is to perform an observational cohort study investigating the use of oxygen reserve index (ORi) in patients undergoing elective thoracic surgery and one-lung ventilation (OLV). For this purpose, ORi values are recorded and compared to the other collected hemodynamical and oximeter parameters. The primary hemodynamic parameters include heart rate (HR) and blood pressure (BP), while; oximeter device-related parameters include peripheral oxygen saturation, perfusion index (PI), and pleth variability index (PVI). The investigators' secondary goal is to investigate relationships between these hemodynamical and oximeter parameters using statistical analysis methods.
