What are the types of dialyzer?
Six types of dialyzer membrane materials were used in the present study: cellulose triacetate (CTA), ethylene-vinyl alcohol co-polymer (EVOH), polyester polymer alloy (PEPA), polyethersulfone (PES), polymethylmethacrylate (PMMA), and polysulfone (PS) (10, 12).
What does the dialyzer do?
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.
What is the safe range for dialysate pH?
Dialysate with a pH below 6.5 or above 7.5* is unsafe. Use the D-6 Dialysate Meter to check the pH and conductivity of the dialysate, as well as the conductivity, pH, and temperature alarm systems, before each dialysis treatment.
What should be checked on a dialyzer before the machine set up?
Conductivity of the final dialysate being delivered to the dialyzer should be checked before every treatment. According to the manufacturers’ instructions, the conductivity may be checked with an independent reference meter which is known to be properly calibrated.
What are the three types of dialyzer?
In addition, dialyzers are internationally classified into three types: low-flux, high-flux, and protein-leaking.
Why does dialysis take 4 hours?
Four hours enable adequate delivery of dialysis through the removal of toxins. More important, together with a sensible dietary sodium intake, 4 hours of dialysis allow an adequate time over which excess fluid volume can be removed without provoking uncomfortable dialysis symptoms.
What is TMP in dialysis?
The major driving force that determines the rate of ultrafiltration or convective flow is the difference in hydrostatic pressure between the blood compartment and the dialysate compartments across the dialysis membrane; this is called the transmembrane pressure (TMP).
Why is bicarbonate used in dialysis?
Bicarbonate administration via the dialysate helps maintain the acid-base balance in these patients. Serum bicarbonate level in dialysis patients is determined by several factors that include dietary protein intake, nutritional status and dialysis prescription, etc.
What is the difference between dialyzer and dialysate?
The dialyzer, or filter, has two parts, one for your blood and one for a washing fluid called dialysate. A thin membrane separates these two parts. Blood cells, protein and other important things remain in your blood because they are too big to pass through the membrane.
What solution should you mix to disinfect the dialysis station?
To clean surfaces and non-treatment items, create a 1:100 bleach solution by mixing 1 teaspoon household bleach with 2 cups water. Mix 1 part household bleach and 10 parts water to clean dialysis equipment.
