Back/Mute
switch
Operation indicator (green flashing)
1)
Press the Back/Mute switch twice to stop the alarm and
return to flow rate screen.
Notes
• The volume delivered reaches the VTBI setting.
• The operation indicator flashes green.
• The screen has changed to the 3.00 mL/h (when 20 drop/mL) or 1.00 mL/h (when
60 drop/mL) flow rate screen (KVO function).
Keep Vein Open (KVO) Function
When the volume delivered reaches the VTBI, the KVO function is activated for the prevention of thrombus formation, and thus the
flow rate is automatically changed to minimum flow rate (20 drop/mL: 3.00 mL/h or 60 drop/mL: 1.00 mL/h). If the set flow rate is
lower than the flow rate of the KVO, solution delivery continues at the set flow rate. If you wish to change the flow rate of the KVO,
contact TERUMO trained service technicians.
Notes
• The KVO is a flow rate set in advance to operate under certain conditions in order to keep the patient line open.
• Note that the symbol KOR (Keep Open Rate) is commonly used as an alias for KVO.
• According to IEC 60601-2-24:2012 (EN 60601-2-24:2015), clause 201.3.209, KVO (Keep Vein Open) is commonly used as a
synonym for KOR (Keep Open Rate).
Caution
• In the case of a solution delivery with no setting for the VTBI (“----.--”: Unlimited), the pump will not stop until an alarm is
issued. The pump should be stopped before running out of the drug solution. It is recommended to set a VTBI slightly less
than the volume of the drug solution container.
