Abstract
Chronic obstructive pulmonary disease (COPD) and other respiratory disorders remain a significant global health concern, necessitating accessible, accurate, and portable diagnostic tools. This study presents the design and development of a Bluetooth-enabled portable spirometer utilizing pressure-volume analysis, integrated with an Android-based platform for real-time health monitoring. The device leverages micro-electromechanical systems (MEMS) flow sensors (Ejeian et al., 2019) and a smart-phone interface to measure pulmonary function parameters, including forced expiratory volume (FEV1) and forced vital capacity (FVC). Experimental evaluation demonstrates that the proposed system delivers high correlation with conventional laboratory spirometers, while offering portability, cost-effectiveness, and remote monitoring capability. Critical technical analysis explores sensor calibration, data acquisition, and signal processing, highlighting performance under varied usage conditions. The study underscores implications for low-resource environments and telemedicine applications, while addressing limitations associated with sensor sensitivity, environmental factors, and patient compliance.
