PURGE CASSETTE PROCEDURES
When replacing the purge cassette, the replacement process must be completed
within 2 minutes. The Impella
®
RP Catheter may be damaged if replacement takes
longer than 2 minutes.
There are four procedures for maintaining the Impella
®
RP Catheter purge system:
• Change purge system (changing cassette and purge fluid)
• Change purge fluid
• Change purge cassette
• De-air purge system
Each procedure can be accessed using the
PURGE SYSTEM
soft button. This section describes
each of these purge cassette procedures.
CHANGE PURGE SYSTEM
Follow these steps to change both the purge cassette and purge fluid:
1.
Press
PURGE SYSTEM
and select “Change Purge System” from the menu.
2.
Open the purge cassette package. Disconnect and discard the Y connector from the
end of the purge tubing as shown in Figure 5.13.
Figure 5.13 Disconnecting the Y Connector from the Purge Cassette Tubing
3.
Spike the fluid bag/bottle.
4.
Select
OK
to deliver a bolus to the pressure reservoir so that the reservoir can maintain
purge pressure during the change. A progress bar shows the progress of the bolus.
After the bolus is delivered, the controller automatically proceeds to the next screen.
5.
Disconnect the yellow luer from the Impella
®
RP Catheter and remove the used purge
cassette.
Replacement Time
If the purge flow is more
than 7 mL/hr or the dextrose
concentration is less than
20%, replacement time
will be less than 2 minutes.
Replacement should always
be performed as quickly as
possible.
Discard the Y Connector
Disconnect and discard the
Y connector from the purge
cassette tubing. For the
Impella
®
RP System, the
yellow luer on the end of the
purge tubing connects directly
to the yellow luer on the
Impella
®
RP Catheter.
