4.3.1 BUBBLE MONITORING: PERFORMANCE TEST
Check that the ROTAFLOW System stops, an acoustic alarm is emitted and the
status display shows
[STOP BUB] when a bubble passes the bubble sensor.
You must reset the bubble sensor after a bubble intervention. To do so, press the
“Bubble override” button briefly (less than 3 seconds).
4.3.2 LEVEL MONITORING: PERFORMANCE TEST
Check that the ROTAFLOW System stops, an acoustic alarm is emitted, and the
status display shows
[STOP LEV] when the level of liquid in the reservoir is lower
than the arrow of the level sensor pad.
4.4 CHECKS BEFORE USAGE
„ Check that the ROTAFLOW System is functioning.
„ Check that the speed display matches the speed set on the flow regulator.
„ Check that the correct mode has been set for the ROTAFLOW Console ( Ö 4.1
“Modes”, page 31).
„ Check that the patient-specific lower flow limit (FLIM) is set correctly ( Ö 4.2
“Selecting settings”, page 33). If the flow is too low, this may be dangerous and
harm the patient.
„ Check every intervention selected by simulating an alarm condition:
– “STAND AL” mode:
– Bubble monitoring: Performance test ( Ö 4.3.1, page 35)
– Level monitoring: Performance test ( Ö 4.3.2, page 35)
– Modes “ART” and “ART PULS”.
Monitoring via monitoring systems of heart-lung machine ( Ö User’s Manual
for heart-lung machine).
WARNING!
Repeat the performance test whenever the level sensor pad is moved. If there is
a malfunction, try a new level sensor pad.
