Monitoring System for Acapella Choice based on Oscillating Frequency and Pressure Level Sensors

Abstract

This paper presents the development of a sensor system prototype designed to monitor the oscillating frequency and pressure levels in the Acapella Choice airway clearance device. The sensor system consists of a differential pressure sensor and a linear Hall-Effect sensor, which enable the measurement of the pressure exerted during exhalation and the detection of airflow oscillations, respectively. The Fast Fourier Transform is applied to analyze the acquired data and extract relevant frequency information. Filtering techniques are implemented to mitigate aliasing and unwanted interference. The proposed sensor system provides information on frequency and pressure parameters during airway clearance therapy, facilitating the improvement of treatment outcomes. The results demonstrate the successful monitoring of oscillating frequency and pressure levels, validating the feasibility and potential utility of the developed sensor system prototype.
