N2  - The administration of oxygen by a catheter inserted in the nose was used in the late war for the treatment of pulmonary edema due to gas poisoning. Introduced by Stokes,1 it was employed with variable results by Douglas,1 Ryle,1 Hamil,1 and Hoover.2 In general, the nasal catheter was considered less effective but more comfortable than the Haldane mask. In 1922 I3 found it to be an effective method of administering oxygen to infants, in whom the oxygen consumption and tidal air were small. Subsequent experience demonstrated that the oxygen concentration of the inspired air could be increased to 30 per cent and the oxygen content of the arterial blood of patients with pneumonia could be considerably elevated if 2 liters a minute of oxygen was delivered through the catheter.4Since that time I have studied the effect of 5 liters a minute of
