Bolus Rate
The bolus infusion rate is the smallest of:
● The maximum infusion rate for the syringe (see “Syringe Data Tables” on page 25).
● The maximum rate established by the RATE RANGE configuration option.
● The bolus maximum rate specified by the selected protocol (if applicable).
Bolus Programming
A bolus may be programmed during an infusion without interrupting the normal delivery.
Note: If a protocol is selected, the bolus function may not be allowed. If the protocol dis-
allows the bolus function, the pump beeps and displays the message
NOT ALLOWED when BOLUS is pressed.
Note: If a protocol has been selected, a default bolus value may appear automatically.
Use ▲ and ▼ or the digit keys to modify this value as necessary, and press
CON-
FIRM
to complete the data entry.
1. Press BOLUS. The status display changes to the Bolus display.
• If there is no programmed bolus size, the pump displays PRESS EDIT TO SET
BOLUS SIZE
. Proceed to step 2.
• If a bolus size has been programmed, the pump displays BOLUS READY. Press
START within 10 seconds to begin bolus delivery, or proceed to step 2 to change
the programmed bolus size, or press
CONFIRM to save the bolus data and return
to the normal display.
Example 1: If a pump is configured for Rate Range = Medium, the overall maximum infusion
rate is 120 mL/hr.
However, the maximum infusion rate for a B-D 10 mL syringe is 107 mL/hr. Therefore, if a B-D
10 mL syringe is used, the bolus rate will be the lesser of the two limits, or 107 mL/hr.
Example 2: Assume that the same pump and syringe from Example 1 are used.
A protocol is selected that specifies a bolus maximum rate of 120 mcg/kg/hr.
If a patient body weight of 50 kg is programmed and the concentration is 0.1 mg/mL, the bolus
maximum rate of 100 mcg/kg/hr will translate to a rate of 60 mL/hr, and the bolus rate will be
limited to 60 mL/hr.
