A New Method for Studying Mechanics of Breathing Using Cathode Ray Oscillograph.

Abstract

Pressure-volume curves may be portrayed directly on the face of a cathode ray oscillograph, obviating the necessity for transposing data obtained as a function of time. Similarly, curves of pressure vs. air flow and lung tension vs. volume may be obtained. The function of time may be included by interrupting the electron beam of the cathode ray tube at regular intervals.
