Boothby and Haines1 have shown that the greatest benefit from the administration of oxygen in cases of cyanosis occurs when the pulmonary lesion has not advanced beyond the stage of congestion and edema. By increasing the oxygen content of the alveolar air, and thus of the blood, the anoxemia is relieved, and the body is better able to resist infection. They have noted that the characteristic drop in temperature which follows shortly after the patient is placed in the oxygen chamber is more pronounced when frank pneumonia has not developed. This is explained by the fact that at this stage the elevated temperature is in a great measure due to the anoxemia. It would appear, therefore, that patients with capillary bronchitis are benefited by the early administration of oxygen.
Fulminating capillary bronchitis is characterized by the sudden development of marked dyspnea, cyanosis and high temperature, coming on during the
