Chapter 3 Working principle and scope of application
3.1 Working principle
This software system is the supporting software part of the pulmonary function tester, and
is used in conjunction with the hardware part of the pulmonary function tester to complete
the forced vital capacity, slow vital capacity, maximal voluntary ventilation and bronchial
diastolic tests.
The software works as follows: 1. Through the USB / Bluetooth acquired detection of
human pulmonary function tests, and increasing the number of data curve data; 2. Read
and calculate curve data. According to the technical principle of the product, each
measurement mode has its own unique breathing mode for detection, and the software can
automatically calculate various pulmonary function parameters in different modes.
3.2 Scope of application
This software system is the supporting software part of the pulmonary function tester. It is
used in conjunction with the hardware part of the pulmonary function tester to complete
