The elastic mechanics of cuff-tissue-bone-artery systems is studied by using the phase-field method. It is shown that such factors as the Young modulus of the tissue, thickness and elasticity of the blood vessel wall, and blood and cuff pressures significantly influence the oscillation waveforms of the cuff pressure and cause difficulties in decoding the cuff measurements. In addition, our simulations point out at additional information in the oscillometric waveform, which can be of help in the blood pressure decoding. The development of the next-generation instruments for blood pressure measurements requires further studies of cuff-tissue-bone-artery systems and elastic properties of human tissue and blood vessel walls.
