本研究以壓力－體積之指數衰減函數關係與Windkessel model為理論基礎，用血壓波形中舒張末期之衰減常數及血管阻抗（R）估算非侵入式連續博動容積紀錄（PVR）之動脈順應性，評估其結果與侵入式主動脈血壓波形之動脈總順應性（TAC）間的關係。並以Liu等人們利用直線函數之壓力－體積關係所估算之動脈順應性及上臂-腳踝脈波傳導速度（baPWV）兩者對本研究所估算之結果進行驗證。

This study is based on the exponential decay function of diastolic blood pressure waveform with regard to the pressure-volume relationship and the two-elements Windkessel model. And exploring the compliance of non-invasive continuous pulse-volume recording (PVR) estimated by the decay constant of diastolic blood pressure waveform and the resistant (R) of vessel goes to estimate the correspondences between the decay constant, the estimated compliance and the total arterial compliance (TAC). The method for compliance calculation is introduced and verified with the linear pressure-volume relationship by Liu et al. while the brachial-ankle pulse wave velocity (baPWV) is employed to validate the result of this study.
