摘要：

Measurement of expiratory parameters provide useful information about overall respiratory system that can be fundamental in categorizing and staging pulmonary diseases. In contrast to the conventional stand-alone Instrument, a PC based virtual instrument for the measurement of expiratory parameters has been proposed In this paper. A flow sensor based on the principle of constant temperature hot-wire anemometry has been developed to measure the airflow through the mouth of the subject during expiration. Output signal of the anemometer is connected to a PC through an analog to digital interface cards PCI 6025E front National Instruments. A virtual instrument with all controls, indicators and display required for the measurement and interpretation of expiratory parameters has been developed using the software package LabVIEW.
