Operation Procedure
Setting VTBI Time
Set up the time period to complete the dose (Default: disabled).
The flow rate is recalculated from the VTBI and VTBI time specified.
To activate this feature, contact TERUMO trained service technicians.
Setting VTBI to enable (ON) also sets VTBI time to enabled (ON).

Notes
• The VTBI time can be set between 00 h 01 min and 99 h 59 min.
• When the VTBI is set to “----.--” (Unlimited), the VTBI time cannot be set.
• If not operated for 10 seconds, the input area moves to the flow rate display.

Cautions
• The flow rate is updated according to the VTBI and VTBI time. Before starting solution delivery, check the value.
• When using the VTBI time setting function, the setting cannot take a flow rate (mL/h) calculation result outside the flow rate
setting range, and therefore it should be reconfigured. [----.--] or [0.00] is displayed, not allowing solution delivery.
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 0.1 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).
Stopping Keep Vein Open
1)
Press the Back/Mute switch twice to stop the alarm and return to flow rate screen.
2)
Press the Stop switch to cancel the Keep Vein Open (KVO) function and the operation stops.
