Wireless breathing system for long term telemonitoring of respiratory activity

The current common goal in medical services and medical information technology is finding solutions for reducing response time of medical treatment, earlier diagnosis, increasing the accuracy of long-time monitoring for people with medical disorders or during recovery from an acute event or surgical procedure, providing an enhancement of their quality of life. Advances in wireless sensor network technology, the overall miniaturization of their associated hardware low-power integrated circuits and wireless communications enable the design of low-cost, miniature and intelligent physiological sensor modules with applications in the medical services. These modules are capable of measuring, processing, communicating one or more physiological parameters and can be integrated into a wireless personal area network (WPAN). The use of wireless low-power breathing module is suitable for continuous long-time monitoring of human respiration for a number of medical conditions requiring analysis of respiratory rhythm, sleep-related breathing disorder, ischemic heart disease etc. In this paper is presented the realization of an intelligent breathing system for patient home care, capable of measuring, real-time local digital signal processing and transmission of respiratory signals, using GSM/GPRS protocol, and, in case of disorder, even alert the medical staff, providing the real-time position of mobile patient.
