In
ACTIVE PHASE:PRIMING
, the air is removed from the dialyzer
by opening and closing the venous clamp intermittently, while the
blood pump runs.
During
ACTIVE PHASE:FIRST FLUSH
, the blood lines and
dialyzer are rinsed with priming solution at the same fl ow rate as in the
priming phase. When the blood pump stops automatically the operator
is asked to connect the dialysis fl uid tubes to the dialyzer and activate
the dialysis fl uid. The process stops after the fi rst fl ush.
If the operator wants to continue, the blood pump is started so as to
initiate
ACTIVE PHASE:SECOND FLUSH
. This makes it possible to
do a fi nal fl ush just before the treatment is initiated. The blood pump
runs at the same speed as in the priming process.
Extra Priming Part
When priming is complete it can be continued by extra priming where
an extra priming volume will be added. The extra priming procedure
can be used if necessary, for instance just before treatment is initiated
or when the extracorporeal circuit needs extra rinsing. Extra priming
parameter values can be preset by an authorized technician to facilitate
the procedure, similar to the ones for manual priming.
Recirculation Priming Part
If requested, priming can be extended by recirculation priming. During
this procedure the same priming fl uid will recirculate in a closed
extracorporeal circuit for a preset period of time. The priming fl uid
in the circuit will be ultra fi ltrated, and needs to be compensated for,
by priming fl uid connected to the circuit via an infusion line. The
time for how long a period the procedure should last, as well as
a recirculation priming UF volume is preset. Based on these two
parameters, the machine calculates the recirculation priming UF rate.
When recirculation priming UF volume and time have been achieved,
the procedure is complete.
Recirculation priming can be used to adapt priming and rinsing to
the routines of the clinic, or to a speci fi c dialyzer or blood lines.
Recirculation priming parameter values can be preset by an authorized
technician to facilitate the procedure; time, recirculation priming UF
volume, blood pump speed and dialysis fl uid fl ow rate.
Before starting the procedure, the extracorporeal blood circuit must
be prepared for recirculation priming in accordance with standard
procedure used by the clinic. The patient ends of the arterial and
venous blood lines must be connected together to make a closed
extracorporeal circuit. Use a disposable blood line connection designed
for this purpose, between the two blood lines. In addition, connect
priming fl uid via an infusion line in a similar way as when infusions
are administered to the extracorporeal blood circuit during treatment.
This is to compensate for the priming fl uid being ultra fi ltrated from the
closed circuit. For information on how to connect the priming fl uid,
see “Infusions during Treatment”, page 3:36 in part 1 of this manual.
