[The application of informatics to mercury gauge plethysmography].

In this study, the authors present a computerized mercury-gauge plethysmography device. The electrical signals collected by the plethysmograph are sent to the computer where they are analyzed by a specially devised interpretation program. The graphs are flashed on the screen, the parameters are automatically and instantly calculated, and a printed-out medical report may be obtained at the end of the test. The various characteristics of the material and the program are presented.
