Development and Evaluation of a Low Cost Cuffless Systolic Blood Pressure Device

Abstract

[abstFig src='/00290002/05.jpg' width='300' text='A cuffless blood pressure device implemented in a chair' ] In this paper, the authors describe the cuffless blood pressure meter prototype, which is targeting at potential long-term automated blood pressure screening. By the proposed cuffless approach, mental stress is reduced, which increases the reliability of measurement. By using a wireless communication medium to transmit data, care staff can store and access readings more easily. The proposed system was developed using low-cost off-the-shelf parts such as Arduino/Wattuino Uno boards and single-board computers. This enables thereby an unobtrusive implementation of such a compact system into furniture, for example. Its intuitive measurement enables care staff to devote more attention to the patient and less to the blood pressure measurement. The proposed system is described in its hard- and software functionality. Furthermore, experimental results confirm the proposed system’s reliability.
