This article describes the modified arterial reservoir in detail. The modified arterial reservoir makes explicit the wave nature of both reservoir () and excess pressure (). The mathematical derivation and methods for estimating in the absence of flow velocity data are described. There is also discussion of zero-flow pressure (), the pressure at which flow through the circulation ceases; its relationship to asymptotic pressure () estimated by the reservoir model; and the physiological interpretation of . A systematic review and meta-analysis provides evidence that differs from mean circulatory filling pressure.
本文详细描述了改良的动脉储液器。改良的动脉储液器使储液器()和超压()的波动性质变得明显。描述了在没有流速数据的情况下进行数学推导和估计的方法。还讨论了零流量压力(),即循环中血流停止时的压力;它与储液器模型估计的渐近压力()的关系;以及 的生理解释。系统评价和荟萃分析提供的证据表明,与平均循环充盈压不同。
