They should be carried out regularly from the first day, and gradually increasedfrom day to day. A verysimple form of apparatus forassisting in expansion of thelung is shown in Fig. 27. Itconsists of a large quart bottlewith a wide neck, with twoglass tubes inserted into it,one of which reaches to thebottom, and the other only justthrough the cork. To the longertube a rubber connection ismade to a glass bottle is nearly filledwith water, and the patientis instructed to blow steadilythrough the tube against theGreater resistance can be.

This can only be done when the pleura asa cavity is closed by the healing of the wound or by theformation of adhesions between the visceral and parietallayers of the pleura. As adhesions are almost alwayspresent to some extent, these exercises can usually becommenced before the wound has healed. The followingexercises are taken from Dr. H. Campbells book onrespiratory exercises : operations on the Thorax 165 Breathing Exercises for One or Both Lungs. I. Exercise for one lung only, in this case to be applied to theaffected lung. One hand is in the axilla of the sound side of the chest,and pressed firmly against the chest wall, so as to check its move-ments as far as possible. The opposite arm is then raised from thes
