Development of portable digital spirometer using NI sbRIO
One of the effective ways to diagnose various respiratory diseases is using spirometry test. Good spirometer comes with excellent graphical user interface. Spirometer is used to measure lung parameters such as FVC (Forced Vital Capacity) and FEV1 (Forced Expiratory Volume in the first second). T...

| Summary: | One of the effective ways to diagnose various
respiratory diseases is using spirometry test. Good spirometer
comes with excellent graphical user interface. Spirometer is used
to measure lung parameters such as FVC (Forced Vital Capacity)
and FEV1 (Forced Expiratory Volume in the first second). The
aim of this project is to develop a portable spirometer using NI
sbRIO FPGA board and LabVIEW Software. The LabVIEW
program consists of two parts: 1) the data acquisition and 2) the
disease diagnosis. The data acquisition part will obtain data from
user in terms of breathed air. Meanwhile, the disease diagnosis
part will use the obtained data to analyze the disease. The system
uses National Instrument Single Board Rio 9636 (NI sbRIO) for
digital data conversion and data acquisition and breathing
hardware from which users will used to flow air into the
spirometer. The breathing hardware uses Venturi’s principle
where the difference of the two pressures with different tube
diameters used to measure flow rate and volume of air exhaled
over a period of time; to determine the respiratory conditions.
Results obtained from three different volunteers with different
health performances are also presented in this paper. The FEV1
ratio of a healthy volunteer is 81.1%, an asthma volunteer is
72.04%, while a volunteer with suspected bronchitis is 33.4%.
Based on these results, unhealthy users tend to have smaller
value of FEV1 with lower area under the curve when compared
to a healthy user. The test results are represented in parameters
of pulmonary functions which include Volume-time and Flowvolume
graphs. |
