One hundred patients were randomized into control and "treatment" groups, in three separate studies, to determine whether hypoxaemia in the immediate postoperative period could be minimized by manoeuvres applied during anaesthesia--intermittent hyperinflation of the lungs, rehydration and the use of an "artificial nose," and the addition of nebulized water to the inspired air. None of the methods studied produced any significant reduction in postoperative hypoxaemia. The relationship of postoperative arterial oxygen tension to age, duration of operation, and arterial carbon dioxide tension was examined statistically.
