What is UF in CRRT?
When ultrafiltration is applied to a circuit or a CRRT treatment, specifications should be made using terms such as total ultrafiltration (UF = overall ultrafiltration volume produced during treatment) and net ultrafiltration (UFNET = net ultrafiltrate volume removed from the patient by the machine).
What is effluent fluid in CRRT?
The total effluent fluid rate is a surrogate of solute clearance provided by CRRT and is used to determine the dose of CRRT in diffusive, convective, and hybrid modalities. The total effluent rate is typically reported in milliliters per hour and adjusted by the patient’s weight in kilograms (mL/kg/h).
How is effluent rate CRRT calculated?
When using Pre-Filter Replacement Fluid and/or Pre-Blood-Pump (PBP) Fluid, the CRRT dose is diluted and therefore decreased. CRRT effluent rate is multiplied by the dilution factor and then divided by patient weight to reflect actual CRRT dose in ml/kg/hr; this takes into account the dilution effect.
What is equilibrated Kt V?
Equilibrated Kt/V or double-pool Kt/V, which accounts for the rebound in the blood urea nitrogen concentration after completion of the dialysis treatment. • Standard weekly Kt/V, which is a measure of total clearance per. week, and as such, accounts for the number of treatments during the. week.
What is convection in CRRT?
CONVECTION. Convection is the one-way movement of solutes through a semi-permeable membrane with a water flow.
What is the difference between CRRT and Cvvhd?
In a recent large observational study, CRRT was used in 60% of critically ill patients with AKI (1). There are two methods of clearance: diffusion and convection. Continuous venovenous hemodiafiltration (CVVHDF) combines diffusion and convection using a highly efficient hemodiafilter to remove both solute and fluid.
Is Cvvhdf better than Cvvh?
CVVH uses convective clearance to remove toxins and solutes from the patients circulation, while CVVHD relies on diffusive clearance to remove these same toxins/solutes. This study will evaluate which of these two methods is more effective at clearing the body of waste/solutes.
Is CRRT same as Cvvhd?
More commonly, when provided as continuous venovenous hemofiltration (CVVH), continuous venovenous hemodialysis (CVVHD), or continuous venovenous hemodiafiltration (CVVHDF), CRRT provides both solute clearance and volume removal, with the differences between these modalities related to the mechanisms for solute …
What is eKdt v dialysis?
eKdt/V = dialysis contribution only to eKt/V. eKdrt/V = dialysis and renal contribution both to eKt/V. stdKt/V = Standard Kt/V= the continuous clearance which is therapeutically equivalent to any schedule (number of dialyses per week) and intensity (eKt/V per dialysis) of intermittent dialysis therapy.
