Step Delivery Mode
Step delivery allows the infusion of a specified volume of drug at an initial rate with linear step increases
up to a plateau rate. Multiple steps down may also be applied, reducing the continuous rate as low as the
initial rate. An optional KVO (keep vein open) rate may be delivered at the end of the infusion, depending
on protocol settings.
The following graph illustrates an example step delivery:
Home Screen
The delivery mode and status of the infusion are indicated on the home screen with messages appearing
in text, a graphic in a shape unique to the therapy, and with the colors green, red, and gray. The
colors indicate that the pump is running (green), or stopped (red). If a new patient or new infusion is
programmed but
the pump has not been started,
or if a delayed start time was programmed and the start
time passed while the pump was stopped and not yet started, the graphic is entirely gray. The location of
the color on the graphic also indicates the status of the infusion. The examples below are specific to the
step delivery mode.
•
The pump is running with a programmed delayed start.
•
The pump is stopped and has not yet reached the plateau.
•
The pump is running at the plateau rate.
•
The pump is running at continuous hold after a manual step down.
•
The pump is running at the KVO rate, nearing the end of the infusion.
Step delivery mode graphics do
not
depict how many steps will be made to reach the plateau. Nor do they
depict the relative step rate increases in comparison to the initial and plateau rates.
