Portable Spirometer using Gas Pressure Sensor For FVC and FEV1 Measurement
Journal Title: Journal of Electronics, Electromedical Engineering, and Medical Informatics - Year 2019, Vol 1, Issue 1
Abstract
Extreme climate change and air pollution caused by dust, smoke, vehicle exhaust gases, and industry can increase the chances of contracting various infectious diseases caused by viruses, especially respiratory infections. Lung volume measurements obtained from the air that is inhaled and exhaled by someone can help doctors diagnose abnormalities in the lungs. The purpose of this study was to develop an affordable pulmonary function measurement system, which is a spirometer. The mainboard consists of a non-inverting amplifier, Arduino microcontroller, LCD and SD Card memory. FVC and FEV1 volume measurements are carried out when the breath blew through the MPX5100DP gas pressure sensor. The sensor’s output is a voltage, which is converted to a volume unit using the venturi meter method. The SD card memory is used to store data. The results of measurement data on respondents with a spirometer comparison device then there is an FVC error of 0.98% 5, FEV1 3.83% and FEVI / FVC 2.50%.
