Definitions
ANALGESIA:
Relief from pain.
BASAL FLOW RATE:
The continuous flow rate. It occurs when the pump is not delivering
a bolus in PCA mode. The basal flow rate is adjustable and has units of milliliters per hour
(ml/hr).
BOLUS:
A volume of medication infused over a relatively short period of time.
1
The bolus
is infused at the bolus flow rate. A bolus is delivered when a patient requests it by pushing the
BOLUS button or the optional remote BOLUS switch. A bolus is sometime referred to as a PCA
bolus. The bolus has units of milliliters (ml).
BOLUS/DOSE FLOW RATE:
The flow rate at which a bolus or dose is delivered. It is
a higher flow rate than the basal flow rate. In the ambIT
®
PIB
v1.5
pumps, the bolus flow rate
varies from 210 ml/hr to 125 ml/hr, depending on the energy left in the battery. Flow rate
accuracy is not affected by the bolus flow rate. See Section 1.4.1 for an explanation of how the
bolus flow rate changes. The bolus/dose flow rate is not adjustable.
CAUTION:
A caution usually appears in front of a procedure or statement. Failure to
observe a caution could result in serious patient or user injury. Cautions are found throughout
this document emphasized with grey shading.
DOSE:
A volume of medication infused over a relatively short period of time
2
and is
programmed to occur at regularly scheduled intervals. Sometimes a dose is referred to as a PIB
or as a PIEB. In this manual, the term “dose” will be used when discussing either PIB or PIEB.
The dose has units of milliliters (ml).
INTERVAL OR DOSE INTERVAL:
The time between the start of one dose and the start
of the next dose. The dose interval has units of hours and minutes (hh:mm).
INTERVAL LIMIT (“IL”):
The maximum amount that can be delivered within a dose interval
and the maximum bolus volume allowed to be programmed. This setting is only applicable to
PIB + PCA (“P+P”) mode for PIB-IL
v1.5
pumps.
LOCKOUT TIME:
The time between the end of one bolus or dose and the start of the next
bolus or dose. The lockout time has units of hours and minutes (hh:mm).
NOTE:
A note highlights information that acts as a reminder or helps explain a concept or
procedure.
P+P:
An acronym for a combination of programmable intermittent bolus (“PIb”) and patient
controlled analgesia (“PCA”) and allows for dose volumes occurring at set intervals, as well as
optional boluses.
1 The bolus is delivered at a higher flow rate than the basal rate; therefore, for a given volume, the bolus is delivered faster.
2 The dose is delivered at a higher flow rate than the basal rate; therefore, for a given volume, the dose is delivered fast.
