Chimata, Raghuveer; Bibi, Sara Boscolo; Hosseiniakram, Pedram; Gatty, Hithesh Kumar – GattyInstruments AB
This study presents a low-cost, easy-to-manufacture novel flow tube that accurately measures respiratory airflow across a wide range, including very low flow rates, while meeting ATS/ERS spirometry standards and enabling precise, high-frequency pulmonary diagnostics.
SPIROLUFT: A Next Generation Breath Analyser Utilising Simultaneous Spirometry & Pulse Oximetry
Date: November 2024
Säfström, Felix – Uppsala University, Disciplinary Domain of Science and Technology, Mathematics and Computer Science, Department of Information Technology.
This work presents the design, implementation, and evaluation of Spiroluft, a mobile embedded spirometer that enables remote diagnosis of pulmonary diseases by simultaneously measuring spirometry and pulse oximetry with accuracy largely compliant with Medical Device Regulation standards.
Development of a Breath Monitoring System Using an STM32 Microcontroller and a Bluetooth Device with Connected MEMS-Based Sensors
Date: May 2024
Ravichandran, Vijayakanna – Uppsala University, Science and Technology Disciplinary Domain, Mathematical and Computer Science Section, Department of Information Technology.
This thesis develops and validates a Bluetooth-enabled, MEMS-based handheld spirometer for home lung function monitoring, demonstrating improved data transmission speed, reliable performance metrics, and effective detection of lung inflammation–related diseases.
