During experimental work in the production and surgical application of closed endobronchial anesthesia the behavior of certain anesthetic gases in the obstructed lung was noted. The ease with which complete bronchial obstruction could be obtained and the speed of absorption of gases from the obstructed lung led us to repeat, by this technic experimental work reported by Coryllos and Birnbaum.1
The importance of atelectasis in the production of postoperative pneumonia, the different opinions expressed as to the etiology of such atelectasis and the varied ideas as to the treatment make the subject important. It is of special interest to the surgical team charged with the responsibility of minimizing any causative factors as well as of instituting immediate and efficient therapeutic measures. Our practice had been to hyperventilate certain patients during recovery from the effects of anesthesia, particularly after anesthetization with ether. Such hyperventilation was commonly done by giving mixtures
