[Hypoxaemia during transportation of patients after anesthesia and upper abdomen surgery]

The incidence of hypoxaemia was studied in 100 patients breathing room air during their transportation from the operating room to the recovery room. Hypoxaemia (SaO2 less than 90%) occurred in 24 (24%) patients. Oxygen saturation rose quickly above 95% when oxygen was administered. The causes of hypoxaemia are discussed. Quick transportation and oxygen supply were recommended.
