slugA Telemedicine Device for Monitoring of Patients with Respiratory Diseases
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 4
Abstract
A wireless portable system for monitoring respiratory diseases using a thermal flow sensor to monitor respiratory air flow, a Triaxis micro accelerometer to monitor the body posture, and a photo electric sensor to monitor blood oxygen saturation, is proposed. The system uses Bluetooth as data communication approach to achieve ubiquity via mobile cellular networks or internet. Algorithms for derivation of respiration parameters and estimation of body posture are proposed. A cellular phone or a laptop connected to the internet will function the monitoring and transfer terminal, so that testing results can be analyzed, recorded or transmitted to a remote center or physicians. Respiratory flow sensor can detect weak respiration. Employing the triaxis accelerometer to detect motion and body posture provides a reference for respiration movement. Different respiratory parameters like tidal volume, peak inspiratory flow, minute volume and respiratory rate are derived from the respiratory flow data obtained. Body postures are classified into two categories: motion and rest. In the motion state, walk/run and other states are identified. In the rest state, different body postures of sit/stand, lie on the back, lie on the face, lie on the right, and lie on the left are identified. This system can be used both as a sleep recorder as well as a spirometer, making the system capable of monitoring and diagnosing various respiratory disorders like obstructive sleep apnea, asthma and chronic obstructive pulmonary disease. A mobile or a laptop connected to the internet serving as the monitoring and transfer terminal makes the system capable of remote monitoring and timely risk alarming when severe respiratory distress occurs.
