        报告摘要:

        Continuous monitoring of blood  pressure, an essential measure of health status, typically requires complex,  costly, and invasive techniques that can expose patients to risks of  complications.  Continuous, cuffless, and noninvasive blood pressure monitoring  methods that correlate measured pulse wave velocity (PWV) to the blood pressure  via the Moens?Korteweg (MK) and Hughes Equations,  offer promising alternatives.  The MK Equation, however, involves two  assumptions that do not hold for human arteries, and the Hughes Equation is  empirical, without any theoretical basis.  The results presented here establish  a relation between the blood pressure P and PWV that does not rely on the Hughes  Equation nor on the assumptions used in the MK Equation.  This relation  degenerates to the MK Equation under extremely low blood pressures, and it  accurately captures the results of in vitro experiments using artificial blood  vessels at comparatively high pressures.  For human arteries, which are well  characterized by the Fung hyperelastic model, a simple formula between P and PWV  is established within the range of human blood pressures.  This formula is  validated by literature data as well as by experiments on human subjects, with  applicability in the determination of blood pressure from PWV in continuous,  cuffless, and noninvasive blood pressure monitoring systems.
