AB - CHAPTER I a. ALVEOLAR AIR SAMPLING Samples of expiratory air, after a "Haldane cough", were delivered to the apparatus shown in Fig. 2. The apparatus consisted of a brass T-tube (22 mm i.d.). The left arm was fitted with a detachable mouthpiece; the right, with a 1000 ml breathing bag (A). In the vertical part of the T was a rubber stopper, penetrated by a piece of rigid polyvinylchloride (PVC) tubing, carrying a football bladder for the alveolar sample (B). The dead space of the apparatus was 43 ml. Fig. 2. Equipment for obtaining samples of alveolar air. A, breathing bag for dead space wash out; B, football bladder for collecting sample of expired air. 10 When the subject expired into this apparatus, with or without the mouthpiece, the breathing bag (A) expanded and when it was full, the final part of the expired air, approximately one liter, filled B. With this device it was also possible to obtain expiratory air samples during breath-hold diving in a training tank (Fig. I). During deep dives the total lung volume to the rise in ambient pressure, with decreased roughly proportionally of the gases in the lungs. A breathing bag of consequent
