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(SpO
₂
) 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.
