Pulmonary artery pulsatility index (PAPi) is a haemodynamic parameter that is derived from right atrial and pulmonary artery pulse pressures. A number of reports have described the prognostic value of PAPi in patients with advanced heart failure and cardiogenic shock. However, the derivation and physiological interpretation of this parameter have received little attention. This review will examine the physiological interpretation and clinical data for PAPi.

肺动脉搏动指数：生理基础和临床应用。

肺动脉搏动指数（PAPi）是从右心房和肺动脉搏动压力得出的血液动力学参数。许多报告描述了PAPi在晚期心力衰竭和心源性休克患者中的预后价值。但是，该参数的推导和生理学解释很少受到关注。这篇综述将检查PAPi的生理学解释和临床数据。
