damage the kidneys

Dialysis basic concepts

All dialysis machine equipped with volume metric UF control.

Blood flow speed is accurately calibrated.-+5%

All modern artificial kidneys (Dialyzers) are semi identical.

Urea clearance affect patients outcome.

Dialyzer clearance depend on blood flow speed.

Dialyzer clearance decreased throughout treatment time.

Delivered blood flow mainly depend on blood access efficacy.

Butter KT/V better patient outcome.

All modern dialyzers tolerate maximum TMP above 500mmhg.

All dialyzers membrane are biocompatible.

Dialysis applied science

common diaysis subjects

compare two dialyzers

you can compare different dialyzer such the type, urea clearance on different blood flow, priming volume

Dialyzer Selection

Get dialyzers which have certain criteria such as surface area, urea clearance, blood volume, UF Coefficient, Mode of Sterilization and Membrane Type

dialysis basic concepts

some concepts to be in mind when dealing with dialysis on real practice

dialyzer biocompatibility

The level of complement activation produced by a membrane is considered a significant determinant of membrane biocompatibilit

Dialyzer Info

basic information about the dialyzers related to type, Surface area , urea and creatinine clearance

DRUG DIALYZABILITY

Check wether the drug is dialyzable or not

dialyzer clearance calculation

to calculate the actual dialyzer clearance for any substance

dialyzer reuse

Single-use dialyzers provide the advantage of reducing the cost of personnel, technician training on dialyzer reuse

Dialyzer selection criteria

In cases where the aim is ultrafiltration not clearance, such as hypervolemia in heart failure

drug dialyzibilty factors

The extent to which a drug is affected by dialysis is determined primarily by several physicochemical characteristics of the drug

hemodialysis prescription

As described by Daugirdas, many excellent nephrologists follow an empiric model when devising the hemodialysis prescription

Influence of design.php

Symmetric membranes, which can be derived either from cellulose or entirely from synthetic polymers, have a homogeneous configuration throughout the membrane wall

Interpretation dialyzer spec

Priming volume is how much blood needs to fill dialyzer capillaries, it consider as dead blood volume. it is varies among dialyzers

hemodialysis dialyzers

Membrane performance, as determined by the effectiveness of solute clearance and biocompatibility, is of greatest concern when choosing a dialyzer.

How the solutes removed

Solute removal in hemodialysis occurs through a combination of diffusion, convection, and adsorption

types of dialyzer Membranes

The materials most commonly used to make hollow fiber membranes include PSf, PES, cellulose triacetate (CTA), polymethylmethacrylate (PMMA), PEPA, ethylene vinyl alcohol copolymers

water quality

During haemodialysis each patient is exposed to approximately 320 to 360 litres of water per week and hence, each patient is exposed to the potential risk of chemical or microbiological contamination
