Upstream Occlusion Testing
If the pump is configured for upstream occlusion detection (see “Configurable Options,” 4-1), the pump performs an
automatic upstream occlusion test the first time
START
is pressed to begin an infusion after power-on, and whenever
START
is pressed to start the infusion after the tubing door has been opened and closed. During the test, the screen
displays
TESTING UP OCCLUSION
, and the
Alert
LED flashes red. The test takes approximately 15 seconds.
Note:
During the start of therapy, the Downstream Occlusion Detection feature is disabled while the pump is performing the
Automatic Upstream Occlusion Test. Make sure the tubing set is not kinked or blocked both upstream and downstream of
the pump. The maximum infusion pressure generated prior to alarm activation may be exceeded if there is a kink or block-
age during the Upstream Occlusion Test. See "Maximum Infusion Pressure Generated" on page 9-2.
If no upstream occlusion is detected, the pump passes the test and the infusion (or bolus, if one is
programmed) will begin automatically.
If an upstream occlusion is detected during the test, the
UPSTREAM OCCLUSION
alarm is triggered. See
Table 6-2 "Alarm Messages and Responses," on page 6-18 for information on resolving this alarm.
Note:
The pump will not begin infusing until it has successfully passed the upstream occlusion test. If an occlusion is detected,
the test will need to be repeated until it passes successfully. See Table 6-2 on page 6-18 for more information.
During the upstream occlusion test, the Air Detection sensor is turned on even if the sensor is configured
to be OFF. If air is detected during the test, the
SET NOT PRIMED
alarm is triggered. See Table 6-2 on
page 6-15 for information on resolving this alarm.
! WARNING !
The tubing set MUST NOT be connected to the patient while priming.
