Prepump Arterial Pressure Monitoring during Hemodialysis: A Mini Review

Chun-Yan Sun, Xia Fu

The monitoring of Prepump Arterial pressure (Pa) during hemodialysis session can not only strengthen the safety of treatment, but also indicate the Vascular Access (VA) function and the rationality of the pump control blood pump flow (Qb) setting on the machine. Despite this, the monitoring of Pa is always ignored and the measurement or safe range of Pa has not yet emerged as a clinical standard in worldwide practice. The absolute value of the ratio of Pa to Qb (|Pa/Qb|) was proved to be an independent risk factor and a predicting factor for arteriovenous fistula function. However, |Pa/Qb| is related to various influencing factors, and attention should be paid to exclude confounding factors and avoid risk factors that contributed to not only change of |Pa/Qb| but also complications of VA.
