Etude et réalisation de spiromètre à base d’un capteur de pression MPX 10 DP

Abstract

Spirometry is the most commonly performed respiratory function test in the world. It is an examination that provides information both on the volumes of pulmonary gas that a subject is capable of mobilizing and on the gas flow rates that this subject is capable of generating during a “forced” maneuver. Spirometry allows, finally and above all, to relate exhaled flow rates to the volumes at which these flow rates are measured; Spirometry makes it possible to collect several physiological quantities. The most commonly used in clinical practice are the forced vital capacity (FVC) and the maximum exhaled flow rate during the first expiratory maneuver. Spirometry can then help identify the pulmonary response. The MPX10DP is a two-port silicon pressure sensor for environmental monitoring systems and level indicators. The MPX10DP pressure sensor is currently used for the design of a spirometer based on an Arduino card (UNO or other type); To amplify physiological signals which are generally in the order of microvolts and millivolts, often using AD620 or INA 126 instrumentation amplifiers.
