The Effect of High-Flow Arteriovenous Fistulas on Systemic Haemodynamics and Brain Oxygenation

Abstract

Qa reduction led to increased COef. This was explained by a decreased proportion of CO running through the AVF in patients with Qa > 2.0 L/min. These observations were mirrored by higher brain oxygenation and might explain HF symptoms and improved haemodynamics even in asymptomatic high Qa patients.
