Abstract

A spirometer is one of medical devices that functions to measure the capacity and volume human lungs. The design of the spirometer consists of several electronic components given as follows. A power supply,MPX5500DP pressure sensor, a non-inverting amplifier, a push button, an Arduino Uno Microcontroller and an LCD display.Calibration of the spirometer is done by filing a balloon with 1000 ml of air which is injected from a syringe of 100 ml capacity and needing 10 time injections for 1000ml of air. Following this step, the 1000ml air of the balloon is released through the mouth piece. The result displayed by the LCD shows 1073.72 ml instead of 1000ml, indicating 7% error. The test mode is carried out it 2 stages. The first stage is by maximum inhaling of air for 1 second duration to measure FEV1 (Forced Expiratory Volume 1 second). Similar to the first stage, the test is done for 5 second duration to measure FVC (Forced Vital Capacity). The test results are displayed by LCD and ratio is taken between FEV1 and FVC for each respondent. It is shown the ratio for 6 respondents under test varies between 82.78% and 94.04%.
