To the Editor:—
In a recent editorial on the dangers of administering high concentrations of oxygen (199: 494, 1967), no mention was made that low flow rates of oxygen are not only lifesaving, but safe. Too many deaths occur because oxygen is withheld from severely ill patients with pulmonary emphysema.Cherniak and Hakimpour recently presented in The Journal (199: 178, 1967) their studies revealing the safety of low flow rates of oxygen. At the same time, Cullen had a similar paper in the American Review of Respiratory Disease (95: 116, 1967). Simpson in England specifically states that since he has used low flow rates of oxygen with a graded increase in the oxygen concentration, he has not encountered ill effects. I have employed this procedure since 1938 and have never seen coma or adverse effects from its use.Naturally, it is disturbing to see reference to one side of a
