THE SPIROMETERS TESTING

B. K. Juroszek

Abstract

The spirometer is a measuring instrument which should give information about some mechanical parameters of the respiratory system in a synonymous and precise means. It consists of two main blocks: 1- the spirometric transducer, which converts non electric value, usually gas flow, into electric signal, 2- the electronic block, which measures, converts and presents the results. Their metrological parameters are usually tested by using a calibrating syringe, forced vital capacity simulator or standard waveforms gathered on a diskette. In this article the author proposes a new method of spirometer testing: two spirometers, i.e. the tested one and the standard one are serially connected into a course of calibrating signals. In this way the user can obtain quick information about tested instrument quality.
