Design and Implementation of Breathing Rate Measurement SystemBased on Accelerometer Sensor

Abstract

Respiratory rate is considered as an important factor in analyzing disease disorders, such as sleeping disorders and other respiratory illness. Researchers have considered the detection of respiration presence, however, calculating the respiration rate as an assessment factor to the respiratory disorders was not fully utilized. According to that, detecting the abnormality in the respiration rate will not be possible due to ignoring this important parameter. In this paper, developing a virtual instrument in laboratory virtual instrument engineering workbench (LabVIEW) by using an accelerometer sensor was mandatory. Accelerometer sensors are attached to the chest and abdominal wall to collect the respiration data while breathing. Then, without losing the measured signals, a converter is used to achieve a measured waveform from the collected signals, and by using a threshold level detector, the abnormality for each case can be detected and saved with the measured data on an Excel sheet. The proposed system provides the possibility of observing the breathing rate by monitoring the patients continuously for long time and concerns to the patient recording comfort with data storing possibility and with the possibility of calculating the breath to breath interval.
