Assessing an access for recirculation
A 77-year-old hemodialysis patient is dialyzed through an AV fistula without any problems with blood flow or excessive outflow pressure. His potassium level is consistently elevated. This thread discusses the role of doing a formal access recirculation study. While this is standard in fellowship training, is this exercise still valid? What do you think?
