No full textDevelopment and Evaluation of Wireless Monitoring Systems for Touchless Respiratory Monitor Validation
No full textThe Touchless Respiratory Monitor (TRM) is a non-invasive system that uses contactless methods to measure respiratory rate and tidal volume. The main technologies employed are LiDAR for tidal volume measurement and a thermal camera for respiratory rate monitoring. These novel methods require validation against established techniques such as capnometry and respiratory inductance plethysmography. Commercial respiratory monitoring equipment is often expensive and dependent on proprietary software, creating barriers to widespread use. To address this, a custom, modular, and low-cost evaluation system was developed to streamline the validation of the TRM. The prototype system integrates a pulse oximeter, capnometer, spirometer, and respiratory inductance plethysmography device, with all data collected wirelessly via an open-source MQTT broker. Validation against commercial monitoring equipment demonstrated that the evaluation system provides accurate and reliable measurements, supporting its use for verifying TRM performance
