Automated Blood Volume Regulation During Hemodialysis

Randomized Crossover Trial of Blood Volume Monitoring–Guided Ultrafiltration Biofeedback to Reduce Intradialytic Hypotensive Episodes with Hemodialysis

“…Those receiving the biofeedback intervention in the randomization period had the same prescription, but had their ultrafiltration rate automatically adjusted during each dialysis session on the basis of the changes in relative blood volume. Blood volume-monitoring technique validation (12,15) and description of the ultrafiltration biofeedback algorithm (Supplemental Figure 2) has been previously published (12,15,31). A single investigator (K.C.W.L.)…”
