Arterial oxygen saturation in 132 patients was measured using a Biox IV oximeter with an ear probe, during transfer from theatre to recovery room following a variety of surgical procedures. Oxygen saturation decreased to 85% or less in 21.9% of patients and to 90% or less in 61.4%. No predictive factors were identified. It is recommended that supplementary oxygen be given to all patients in the immediate postoperative period, including the period of transit to the recovery room.
