3.2 Definitions of terms used
Basal rate
The basal rate is a continuous flow rate that can be programmed in ml/h, mg/h or μg/h.
The infusion ends when the programmed Volume To Be Infused has been delivered.
Concentration
The drug concentration is required to calculate the basal rate while programming
units mg or μg are used, with the following formula.
Output rate when calculated using the drug concentration is calculated with two
decimals accuracy.
Programming units can be changed either from the basal rate programming screen
after the start of programming or from the concentration programming screen.
When programming in ml/h the concentration is ignored.
Patient Bolus dose
The patient bolus (also called Bolus on the pump screen) is an amount of drug
delivered at patient request, in addition to the basal rate and to the automatic bolus,
if any.
The patient bolus delivery rate is the same as the automatic bolus delivery rate and
is configurable through the Configuration menu and its default value is 100 ml/h. The
patient bolus is delivered when the patient demand is valid (not within the lockout
interval), the pump is not alarming the bolus limit or the dose limit has not been
reached and the patient bolus dose will not increase the infused volume to reach
the dose limit.
Lockout interval
The lockout interval is the period of time when the patient bolus demand cannot
be delivered to the patient. This period starts after the delivery of a patient bolus or
clinician override or an automatic bolus or loading dose.
Automatic Bolus dose
The automatic bolus (also called Auto Bolus on the pump screen) is an amount
of drug delivered automatically and periodically in addition to the basal rate. The
automatic bolus delivery rate is the same as the rate used to deliver the patient bolus.
The automatic bolus is delivered when the pump is not alarming and the dose limit
has not been reached.
