Automatic Bolus Frequency
The automatic bolus frequency (also called Auto Bolus Frequency on the pump
screen) defines the period of time between two automatic boluses.
Dose limit
The dose limit gives the capability to restrict the amount of drug that a patient can
get within a period of time.
The entire drug volume infused by the pump, including loading dose, basal rate,
clinician override boluses, patient boluses and automatic boluses are counted. A
patient bolus will be infused if the total infused volume will not exceed the dose limit
programmed. When the programmed limit is reached, the pump stops delivering
drug. A warning is displayed. When the amount of drug within the pre-set period of
time decreases bellow the dose limit, then the delivery restarts automatically.
The observation window is a shifting window during which all infused volume is
totalized. Every 5 minutes a new totalizer is started creating a shifting observation
window of the totalised infused volume.
If the dose limit alarm is triggered by a bolus, the bolus will not restart at the end of
the dose limit alarm.
Bolus limit
The bolus limit gives the capability to restrict the number of patient bolus that a
patient can get within a period of time.
Only the patient requested boluses given by the pump are counted. Clinician
override boluses and automatic boluses are not counted. When the programmed
limit is reached, no more patient bolus demand is delivered. A warning is displayed.
If a basal rate and or automatic bolus has been set, the flow rate is maintained
and automatic boluses will be infused. When the number of patient bolus within
the pre-set period of time decreases bellow the bolus limit, then patient bolus are
automatically authorised again.
The observation window is a shifting window during which all infused patient boluses
are totalized. Every 5 minutes a new totalizer is started creating a shifting observation
window of the totalised infused patient boluses.
Loading dose
The loading dose is an amount of drug delivered by the pump when initiating the
infusion to a new patient.
The loading dose parameter is programmable during the programming phase, as
long as it has been enabled through the pump configuration menu. The loading dose
is delivered immediately after the start of the infusion. After the loading dose has
been delivered, the pump infuses the basal rate if any.
If the loading dose is interrupted by stopping the infusion with the , then the
pump will ask whether or not to finish it when resuming the infusion.
