N2 - Non-invasive blood pressure (BP) measurements are usually performed by means of an empirical interpretation of arterial oscillations recorded via cuff based oscillometic methods. Extensive effort has been put into development of a theoretical treatment of oscillometry aiming at more accurate BP estimations and measurement of additional hemodynamic parameters. However, oscillometry is still basically a heuristic method for BP inference.This study introduces an experimental setup and discusses experimental results to improve understanding of cuff characteristics and the process by which oscillometric signals are produced, with the aim of improving cuff-based non-invasive BP measurement technology relevant in clinical practice. The work focuses on mechanical simulations of arm volume pulsations in cuff pressure signals. The effects of air compression within the cuff and the influence of viscoelastic properties of exterior cuff material are also investigated. Additionally, arm volume changes and compressibility of arm tissue due to external cuff pressure were studied with an MRI system. Our results reveal novel insights into oscillometry and enable understanding of transducer design for cuffs including the importance of viscoelastic material properties and effects of cuff inflation on arm tissue.
