A Clinically Validated Patient Monitoring System

ABSTRACT We present a clinically validated patient monitoring system composed of a wearable sensing unit, a portable data recorder and a remote station with software for acquiring, processing, archiving and visualizing recorded physiological data. The sensing unit simultaneously measures ECG, pulse oximetry, blood pressure, activity/posture, temperature, and respiration rate in an unobtrusive, noninvasive and modular way by integrating and synchronizing proprietary and commercial sensors. The system received Swissmedic’s authorization to be clinically validated at the Department of Intensive Care Medicine of Bern University Hospital. It was tested in a controlled environment and the recorded signals were compared to medical reference measurements from the devices of the Department of Intensive Care Medicine. Three healthy subjects were monitored for three sessions of 17 hours and one of 24 hours. All sessions were composed of usual daily activities such as office work, walking, jogging, and night sleeping.
