4.5 FLOW REGULATION
The flow is kept constant with flow regulation.
1 Set a flow above 0.5 l/min.
2 Press the “LPM Mode” button for at least 3 seconds.
The current flow is allocated to the current speed scale position.
The “LPM Mode” button lights up.
3 You can now adjust the flow (instead of the speed) using the flow regulator.
Press the “LPM Mode” button again to return to speed regulation. The “LPM
Mode” button is extinguished.
4.6 “STAND AL” MODE: INTERVENTIONS
In “STAND AL” mode the following interventions can be used:
„ Stop when bubbles are detected
„ Stop when the level of liquid in the reservoir is low
Monitoring is performed by the internal bubble sensor of the ROTAFLOW Drive
and a level sensor, which is connected to the ROTAFLOW Console.
WARNING!
„ If a bubble, level or pressure intervention occurs during flow regulation, the
ROTAFLOW System will aim for a flow of 0 l/min. This does not however
necessarily correspond to a speed of 0 rpm.
„ Never clamp a tube during flow regulation ( Ö 1.2.1 “Clamping the tube”, page
10). With a clamped tube, the ROTAFLOW Centrifugal Pump can still reach a
maximum speed of 5000 rpm even when the system is aiming for a flow of 0 l/
min.
„ The ROTAFLOW System should only be used with a valve or other adequate
systems or methods (e.g., two tube clamps) preventing a reverse flow.
„ Set the patient-specific upper speed limit (HLIM) correctly ( Ö 4.2 “Selecting
settings”, page 33). If the speed is too high, this may be dangerous and harm
the patient.
Recommendation: Use speed regulation in aircraft .
Extreme electromagnetic radiation may occur during transportation in aircraft –
possibly impairing flow regulation.
It is therefore recommended to use speed regulation during transportation in
aircraft and not flow regulation.
