It is time to implement prepump arterial pressure monitoring during hemodialysis: A retrospective multicenter study

Abstract: Introduction: Prepump arterial pressure (Pa) indicates the ease or difficulty with which the blood pump can draw blood from vascular access (inflow) during hemodialysis. The absolute prepump arterial pressure to blood pump speed (Qb) ratio (|Pa/Qb|) may reflect the dysfunction of other vascular accesses. There is no consensus on the impact of |Pa/Qb| on arteriovenous fistula dysfunction. This study aimed to demonstrate the impact of |Pa/Qb| on arteriovenous fistula dysfunction. Methods: In this retrospective a… Show more

“…Chan et al performed an observational matched cohort analysis among 40,132 Medicare beneficiaries receiving hemodialysis with a fistula or graft. 21 PTA was found to be frequent at a rate of 20.9 procedures per 100 access years. Angiography and PTA significantly increased access survival when compared with nonintervention.…”

“…Excessive negative PPAP can lead to a decrease in the delivery of blood flow, inadequate dialysis, and hemolysis and in most settings is restricted to a value of −250 mm Hg. Unfortunately, these recommendations are often disregarded in clinical practice with pressure sensors being “removed” from the dialysis circuit 21 . The absolute PPAP to blood pump speed (Qb) ratio which we term AAPR may reflect dysfunction of the vascular access.…”
