Measure
Standard Care
This arm of subjects will have all aspects of fluid management and dialysis management managed by the his/her individual nephrologist
IBPS Group
This group will have ultrafiltration prescriptions dictated by a pre-specified protocol that is based on monthly assessment of intradialytic blood pressure slopes obtained over a two week period.

Standard Deviation 6.7

SECONDARY outcome

Timeframe: Baseline, 4 months

Population: In the Standard of Care arm/ group, it was not possible to obtain these measurements in 3 subjects (amputations, defibrillators, implanted metal) and are missing the data since they were unable to undergo these measurements.
