This treat-ment is contraindicated if adhesions so fix the diseased lung that itcannot be made to collapse. Several methods of introducing the gas are resorted to. Thesimplest is that by Forlanini. This consists in introducing a smallaspirating needle, preferably in the fifth or sixth intercostal space,in the mid-axillary line or anywhere the pleura is free, the patient.

Through this needle is slowly passedpure nitrogen gas to the extent of from 200 to 300 cc, but it is not somuch a question of the amount of gas as of the pressure lung should not be compressed by a very large single injectionexcept when it is necessary to control hemoptysis. (See below.)About this quantity is injected on alternate days until completecollapse of the lung is gradually induced. The degree of collapseshould be estimated not only by ordinary methods of physicaldiagnosis but by the aid of the x-rays. Nitrogen gas is used becauseit is less rapidly absorbed than atmospheric air, and so better main-tains the pressure but atmospheric air is commonly employed. Thegas or air should be warmed to body temperature before it is U-shaped glass tube partly filled with water, and provided witha scale in millimete
