Redundant measurement of vital signs in a wearable monitor to overcome movement artifacts in home health care environment

Abstract

This paper shows the design of a wearable device for measuring vital signs, oriented to monitoring applications and home health care. In order to improve the living conditions of the patient, device allows that the patient can perform their daily activities while their health is monitored. The designed device allows measuring electrocardiogram, blood oxygen saturation, non-invasive blood pressure and heart rate. This paper proposes a novel technique to reduce motion artifacts based on signals measurement redundantly, also the importance at clinic level of measuring these variables is shown. The device transmits the information wirelessly to a proprietary application for viewing, the result of used technique for reducing artifacts is shown and a prototype of the device is presented. Finally, the advantages and future improvements of the wearable monitor are discussed.
