What are the three types of dialyzer?
In addition, dialyzers are internationally classified into three types: low-flux, high-flux, and protein-leaking.
What is Polyflux dialyzer?
The Polyflux L dialyzer series is specialized for low-flux hemodialysis treatments, featuring a distinctive membrane that acts as an effective barrier to potential fluid contaminants, while still delivering high performance6.
What is biocompatible dialyzer?
There is no consensus on the definition of biocompatibility for dialyzer membranes. An operational definition of biocompatibility is the lack of any perturbation of blood constituents.
What is a Revaclear dialyzer?
The Revaclear dialyzer series is a range of high-efficiency, high-flux dialyzers designed to enhance safety and biocompatibility for your patients, as well as optimize clearance, with a smaller surface area6.
What is high flux dialyzer?
High-flux dialysis is defined as a β2-microglobulin clearance of over 20 ml/min (1, 2).
How do I choose a dialyzer?
The National Kidney Foundation recommends that dialyzers for reuse should have a blood compartment volume ≥80% of the original measured volume or a urea (or ionic) clearance ≥90% of the original clearance.
What is the function of dialyzer?
A dialyzer is often referred to as an “artificial kidney.” Its function is to remove the excess wastes and fluid from the blood, when the patient’s kidneys can no longer perform that task. Dialyzers are made of a thin, fibrous material.
Which dialysis membrane is the most biocompatible?
Unmodified cellulose membranes, such as cuprophan, are relatively inexpensive but also the most bioincompatible. The modified cellulose membranes (such as those made of cellulose acetate or hemophan) have some or all of the hydroxyl groups esterified to make them more biocompatible.
What is biocompatible membrane?
A biocompatible membrane (BCM) has traditionally been defined as “one that elicits the least amount of inflammatory response in patients exposed to it” [1]. (See “Biochemical mechanisms involved in blood-hemodialysis membrane interactions”.)
What is the difference between low flux and high flux dialyzer?
High flux membranes compared to low flux have larger pores and allow diffusion of greater amounts of uremic toxins and middle molecules such as β2 microglobuline and therefore they may decrease the risk of dialysis-related amyloidosis (3, 4).
What is KT V in dialysis?
The Kt/V is a dimensionless ratio representing the fractional urea clearance. K is the dialyzer blood water urea clearance (mL/minute or L/hour), t is the dialysis treatment length (minutes or hours), and V is the distribution volume of urea (mL or L).
What is the difference between high efficiency and a high flux dialyzer?
Some authors have defined high-efficiency hemodialysis as treatment in which the urea clearance rate exceeds 210 mL/min. High-flux dialysis, arbitrarily defined as a β2-microglobulin clearance of over 20 mL/min, is achieved using high-flux membranes [3,4].
