, the pump infuses at the rate setting for the pump. The infusing indicators are illuminated, and the total
volume delivered (or total dose delivered) accumulates.
Starting Delivery
You can start the infusion at
any time
when the pump is on S

screen.
1.
To start infusion from standby or pause, press the
Start
button.
2.
While you are running an infusion, you may:
a)
Lock the keypad.
b)
Change the Dosage Rate.
c)
Titrate the Rate
d)

), the screen indicates the
effective delivery rate and time remaining to complete the infusion. Bolus, changing
rate, and titrating rate, are
not allowed
in this delivery mode
Stopping Delivery
You can stop infusion delivery at any time.
1.
Press the
Stop
button.

d)
Turn off the pump.
Occlusion Trend Graph During Delivery
The pump automatically monitors
occlusion
or syringe backpressure during any infusion. This trend appears in a
bar
graph
on the right side of the display during delivery. The letter at the top of the graph indicates the configured
occlusion alarm level:
Code
Meaning
Relative Pressure
VH
Fixed for 1ml syringe at very high
35 psi (248 kPa)
H
high
16 psi (110 kPa)
N
normal
12 psi (83 kPa)
L
low
8 psi (55 kPa)
VL
very low
4 psi (28 kPa)
Pressures in above table are only approximations. This is because syringe friction affects the actual pressure level.
Occlusion limit default is set in the custom configurations (see Configuration Manual).
