A:136 AK 98 Dialysis Machine - DIASCAN
HCEN12745 Revision 10.2016
Program version 2.xx
9.1 How DIASCAN function works
NOTE!
The DIASCAN feature is not available on all product configurations of the AK 98
dialysis machine.
The DIASCAN function measures clearance.
The DIASCAN function can be used to:
● review the current dialysis efficiency for the ongoing treatment
● check that the prescribed dialysis dose is being maintained which provides quality
assurance for the treatments
● constantly calculate if the desired and minimum values for Kt/V, set by the operator
for each individual patient, can be reached at treatment end.
The conductivity of the dialysis fluid is measured before and after the dialyzer. Based
on these measurements the clearance for sodium is calculated, which gives a
representative clearance value for small molecules. Each waste substance in the
blood has its own specific clearance that depends on the properties of the waste
substance and the characteristics of the dialyzer.
Clearance data generated by the machine has been validated with clearance data
which is based on blood urea data collected during dialysis.

Diseases, vol.38, No.3 (September), 2001: pp 565-574.
9.2 What DIASCAN function checks
When the treatment has started, the dialysis machine can measure and calculate
these parameters:
● clearance (K) — how much blood is cleaned per time unit (mL/min), this is related
to the dialyzer used and the blood flow rates.
● clearance multiplied by treatment time (Kt) — the volume of blood that has
been cleaned so far in the treatment.
● clearance multiplied by treatment time and divided with patients fluid
distribution volume (Kt/V) — the patient’s dialysis dose. When Kt/V is 1.0, all of
the patient’s fluid distribution volume has been cleaned once.
To start checking clearance, go to the instruction you need:
●
Section 9.3 “Check K and Kt” on pageA:136
●
Section 9.4 “Check Kt/V” on pageA:137
9.3 Check K and Kt
The dialysis machine can measure clearance (K) and calculate Kt as a single
measurement or at intervals.
NOTE!
The dialysis machine needs a certain amount of time to measure. Do not start single
measutement if there is less than 30 minutes left of the treatment time.
Procedure
1) Press the Diascan button.
