A ubiquitous multiple-radio patient vital sign capture platform

This paper presents the design and implementation of an intelligent vital sign capture platform, namely uVS, which provides end-to-end connectivity between patient monitors and Electronic Healthcare Record (EHR) and remote medical staff by employing multiple communications technologies. By replacing manual operation with computer-assisted workflow and ubiquitous networking, uVS aims to enhance reliability, save time and costs for patient´s monitoring routines carried out in hospitals, clinics and emergency sites. Using advanced wireless communications technologies, it allows medical staff to access to patient health conditions from EHR from anywhere at anytime in order to have fast and efficient responses to emergency situations. Network architecture and system design of uVS are first presented. Communications protocols to enable data exchange between various system entities are explained. Finally, system prototypes and preliminary experiment results are presented.
