Wearable wireless physiological monitoring could allow front-line combat medics and civilian emergency responders to quickly prioritize medical intervention, thereby saving critically injured patients. In this paper, we describe the design and implementation of a new power efficient, PDA-based, mobile pulse oximetry system that uses 802.11b two-way wireless communication to acquire, display, and store heart rate, arterial oxygen saturation, body acceleration and posture information from an optical reflectance sensor and a MEMS accelerometer. This prototype system is intended for future military and civilian applications.
