Pervasive health care system for monitoring oxygen saturation using pulse oximeter sensor

Increase in the world´s population, along with an increase in the spread of chronic illnesses and obesity which requires adaption and modification of current healthcare models. Blood oxygen saturation is one of the main parameter for health monitoring of person at the intensive care unit and person with Chronic Diseases. Hence Tele health applications are developed based on sensor technologies for continuous monitoring. Recent technological development, particularly involving micro electro mechanical systems, has resulted in miniaturized wearable devices that can be used for a range of applications. The proposed method demonstrates a design of a wearable wireless blood saturation monitoring system. The system should capable for measuring and transmitting patient´s arterial blood-oxygen saturation (SpO2) level and heart rate (HR). We use commercially available sensing devices, low power microcontrollers and modem that perform the measurements (SpO2 and HR) and transmit them to the patient monitoring device. The monitoring device which is available in form of a PDA runs a personal SpO2 monitor application, receives the SpO2 level and Heart Rate activates the alarms when the monitored parameters exceed the Threshold limits that communicates periodically to the Telemonitoring server by using GSM Modem. This project is a real time application with low cost and flexible to the user convince.
