Delivery at KVO Rate
The
keep vein open
feature is intended for use when you are delivering a series of infusions to a patient, and wish to
ensure the delivery site remains patent between the end of one infusion and the beginning of the next.
1.
Set the delivery mode you want to use for infusion.
2.
Select and set the Volume Limit option.
3.
Select and set the KVO option.
4.
Press
Start
to begin an infusion.
5.
Normal delivery ceases when the pump reaches the programmed volume limit. The pump then begins to
infuse at the preset keep-vein-open (KVO) delivery rate, or the infusion rate at the time the volume limit is
reached, whichever is less.
6.
Here, the pump triggers a KVO alarm – informing you the infusion is complete & the pump is infusing at
KVO rate.
7.
KVO delivery terminates when the syringe is empty, or if you press the
Stop
button. When the pump
automatically stops keep vein open infusion, it sounds a “syringe empty” alarm.
Stop KVO
Infusion
You can stop a KVO infusion at any time by pressing the
Stop
button.
Silence KVO
Alarm
You can silence the alarm by pressing
