During the Standby, Rinse, and Prime Modes (and Dialyze Mode
when the blood pump is manually turned off), the arterial pressure
alarm limits are wide open (–300 to +600 mmHg). The venous
pressure alarm limits are set ±200 mmHg around the indicated
venous pressure at the beginning of the Rinse Mode or 10 seconds
after the blood pump rate is changed.
During Prime Mode (with the extracorporeal alarms armed) and
Dialyze Mode the Instrument will perform as follows:
•
•
•
•
Blood Pump (BP) is started
BP rate display changed
Level adjust buttons pushed
RESET button touched.
The arterial and venous pressure alarm limits open to ±200 mmHg
around the appropriate indicated pressure. After 10 seconds, the
arterial and venous alarm limits close to ±50 mmHg around the
respective pressure with the low venous alarm limit being no less
than +10 mmHg.
