Study Notes

Fluid Overload in Hemodialysis

46% of hemodialysis patients exhibit fluid overload (FO) at baseline, with pre-dialysis blood pressure 7.8 mmHg higher in FO population.
Blood pressure alone is not sensitive enough to identify all FO patients.

Prevalence of Fluid Overload in US Hemodialysis Population

43% of pre-HD patients have fluid overload, 53% are normo-hydrated, and 4% are dehydrated.
48% of pre-HD FO patients are hypertensive, with a moderate correlation between BP and FO.

Impact of Fluid Overload on Organs

Fluid overload can lead to organ dysfunction and adverse outcomes, including hypovolemia, euvolemia, and hypervolemia.
Underfiltration and overfiltration can cause nausea, vomiting, bleeding, and cardiac stunning.

Volume Overload and Mortality

Volume overload is associated with all-cause mortality and cardiovascular events.
Continuous monitoring of percent change in blood volume during dialysis can help identify fluid overload.

Crit-Line Technology

Crit-Line technology non-invasively measures hematocrit, oxygen saturation, and percent change in blood volume.
The technology employs a sensor clip that emits multiple wavelengths of light to transilluminate the blood in the Crit-Line blood chamber.
Real-time monitoring of blood volume changes can help clinicians provide proactive support during HD treatment.

Crit-Line Profile Graph

The Crit-Line profile graph visualizes the rate of blood volume reduction (RBVΔ) and suggests interventions to manage fluid overload.
Three Crit-Line profiles indicate the rate of plasma refill: A (BV reduction < 3%/hr), B (BV reduction 3-6.5%/hr), and C (BV reduction > 6.5%/hr).

Predictive Model for Intradialytic Relative Blood Volume

A predictive model using Crit-Line and HD machine data can identify patients at risk of rapid blood volume reduction.
The top predictors of a RBV decrease of at least -6.5 % per hour include ultrafiltration rate, patient weight, and blood pressure.
