Transcutaneous oxygen saturation of haemoglobin was measured in 101 patients en route from the operating room to the recovery room. Twenty-nine became significantly hypoxaemic during the journey.
The incidence of hypoxaemia was not found to relate to age, weight, duration or type of surgery, type of anaesthesia or pre-existing disease. Duration of the interval between cessation of oxygen in the operating room and arrival in recovery room was the only significant finding in patients who became hypoxaemic.
