Caution
Before the treatment, check:
– The safe connection of all connection sites of the tubing system.
– The tightness of the tubing system during and after priming.
– Retighten the connections and replace the tubing system, if
necessary.
– The absence of air in the tubing system and the correct position of
all fluid levels.
To be observed when working on the tubing system during the
treatment:
If the position of the tubing system or of one of its components is
changed, the correct position of the entire tubing system must be
restored afterwards, above all the correct position of the line guides.
During the treatment check at appropriate intervals:
– The condition of the patient.
– The function of the hemodialysis system and the extracorporeal
blood circuit. Pay particular attention to the venous insertion site, as
a possible dislocation of the venous cannula may not always be
detected by the pressure monitoring system.
– The tubing system for leakages or possible loosening of connections
as well as entry of air.
– The fluid level in the venous bubble catcher. Correct it, if required
(desired level: approx. 1 cm below the upper edge of the cover)
Caution
Venous alarm limit:
The lower venous alarm limit must be set as close as possible to the
actual venous pressure value.
Note
The dialyzer holder is not suitable for rectangular plate dialyzers.
Note
For hygienic reasons, the blood lines should be inserted immediately
prior to the treatment only.
If the blood lines were inserted more than 8 hours before the treatment,
malfunctions may occur. Correcting these malfunctions may require
removing the present blood lines and inserting new blood lines.
