“…All patients in this and our previous study (Catley et al 1985) had normal lung function prior to operation, but major surgery is associated with postoperative hypoxia (Jones 1983) and, against this background, episodes of partial and total upper airway obstruction caused profound decreases in Sao2 lasting up to two minutes, the lowest saturation being 72% (Pao2 38 mmHg). Mild hypoxaemia (Sao2=85% for 20 minutes) impairs short-term memory (Crow & Kelman 1971).…”

“…During the 12-hour study period there was a gradual shift to higher levels of Sao2 when breathing air. (Catley et al 1985) it has been shown that during the postoperative period there is an association between respiratory disturbances, sleep and opiate analgesia; this has been discussed in greater detail by Catley (1984 (Catley et al 1985). There was a gradual diminution in the time spent at low oxygen saturation during the 12-hour study period.…”

“…The transducers measured changes in cross-sectional area virtually independent of the shape of the torso. The RIP transducer was calibrated as described by Catley et al (1985), then an ear oximeter (Hewlett Packard 47210A) was attached to the patient and recordings of oxygen saturation and ventilatory pattern were made on a polygraphic recorder (SLE 10/8) and on magnetic tape (Racal, Store 4 taperecorder). Recordings of the electroencephalogram (EEG) and electrooculogram (EOG) were made on the polygraphic recorder for subsequent assessment of sleep stages.…”

“…In a follow-up study the effects of surgery and general anaesthesia on breathing patterns and oxygenation in the postoperative period were studied in two groups of patients (Catley et al 1983(Catley et al , 1985. It was expected that apnoeic periods might cause profound decreases in arterial oxygen saturation (Sao2), especially when superimposed upon a persistent abnormality of gas exchange which is particularly notable after upper abdominal or thoracic surgery.…”

Summary: Six patients were studied following general anaesthesia for cholecystectomy or hip replacement. Intravenous morphine was given for postoperative pain relief. Continuous measurements were made of breathing pattern and arterial oxygen saturation for a 12-hour period postoperatively. The effect of breathing either air or 28% oxygen for alternate 2-hour periods was examined. There was no significant effect of oxygen on the number of periods of central apnoea, obstructive apnoea or partial upper airways obstruction. The number of episodes of decreases in oxygen saturation to below 80%, associated with these breathing disturbances, was reduced from 59 to zero by the administration of oxygen. There was a gradual improvement in oxygenation whilst breathing air during the 12-hour postoperative period. The administration of oxygen had a beneficial effect on average arterial oxygen saturation.

“…Apnoea was seen in quite young patients of normal weight (Catley et al 1985) While the characteristics of sleep apnoea in the elderly and in the postoperative period are similar 0 5© 1985 The Royal Society of Medicine in many respects, sleep apnoea in infancy presents a much more difficult problem for analysis. Prolonged central apnoea (Steinschneider 1972) or obstructive apnoea (Guilleminault et al 1975) are postulated mechanisms of death in the sudden infant death syndrome (SIDS).…”
