Oxygen Saturation Monitoring During Transport Between the Operating Room and the Post-anesthesia Care Unit

Reduction of the incidence of desaturations

To evaluate whether continuous SpO₂ monitoring during transfer between the operating room and the PACU reduces the incidence of desaturations by recording: * The last SpO₂ reading taken upon leaving the operating room * The first SpO₂ reading taken upon arrival in the recovery room * The lowest SpO₂ reading taken during the transfer between the operating room and the recovery room (for patients monitored by pulse oximetry)

Time frame: upon Arrival in the Recovery Room
