Abstract

This paper presents a novel patient location solutionusing an RSSI (Received Signal Strength Indicator)fingerprinting method, integrated into an ambulatory patientmonitoring device. Results show that patients can be located in apedestrian-rich environment to a typical accuracy of 2m in realtimewith only a basic training sequence for the system. Inaddition, coupled with accelerometer, ECG and respiration ratetechnology, medical staff can know exactly where a patient islocated and what medical requirement to expect when they getthere; e.g., requirement for defibrillation equipment, first aiddue to a fall, etc. This offers a robust and dependable wirelesssystem that increases patient safety and freedom, while allowingclinicians ability to meet patients’ needs in a flexible way.
