Ubiquitous monitoring system for chronic obstructive pulmonary disease and heart disease patients.

The Purpose of this paper is to report a code division multiple access (CDMA) based wireless device that is able to measure pulse oxygen saturation(SpO2) and Electrocardiogram(ECG) during chronic obstructive pulmonary disease and heart disease patients' daily life at home. Global Positioning System (GPS) and a specific database system are also included in this device to trace patient's location. Unlike the pre-reported devices using wireless network like Bluetooth or Zigbee which has a limited connection area, the developed system enables the literally ubiquitous service in reporting the patient's data to their doctors at any time and any place using the CDMA-based cellular phone network.
