Ambit PIB v1.5 - PIb Mode Programming

3.2.2 PIbMode
NOTE: PIbstandsforprogrammableintermittentbolusorautomaticbolus;however,
to avoid confusion, this manual uses the term “dose” when referring to PIb or
PIEb.(seeDenitionsinSection3.2.2below).
PIb mode allows the patient to receive regularly occurring doses of medication. These doses are
delivered automatically at regular intervals. There is not a PCA bolus option in this mode (see
Section 3.2.2 for programming instructions).
3.2.2.1 PIbModeProgramParametersandDenitions.
• A dose is a volume of medication infused over a relatively short period
of time
17
and is programmed to occur at scheduled intervals. Sometimes
a dose is referred to as a programmed intermittent bolus (PIb) or as a
programmed intermittent epidural bolus (PIEb)
18
. In this manual, the
term “dose” will be used when discussing either PIb or PIEb. The dose
has units of milliliters (ml).
• Thebolus/doserateistheowrateatwhichabolusordoseis
delivered.Itisahigherowratethanthebasalowrate.IntheambIT
®
PIB v1.5 pumps,thebolusow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/doseowrate.SeeSection1.4.1foranexplanation
ofhowthebolusowratechanges.Thebolus/doseowrateisnot
adjustable.
• Interval or dose interval is 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).
• PIb is an acronym for patient-intermittent bolus. If the infusion is into
the epidural space, the PIb is referred to as patient-intermittent epidural
bolus (PIEb)
• Thevolumetobeinfusedisthetotalamountofuidinthesolution
container or reservoir to be infused. The volume to be infused has units
of milliliters (ml).
NOTE: When programming PIb mode, if the tens and/or ones digits are already set to the
desired setting, press the RUN/PAUSE and the BOLUS buttons at the same time
untilabeepisheardtoacceptthesettingandmoveontothenextstep.Thisoption
isnotavailablewhenaparameterisprogrammedtoitsmaximumvalue.
SeeSection1.4.1foranexplanationofthepatternofowavailableinPIbmode;specically,
dose only (Figure 1-4).
17 Thedoseisdeliveredatahigherowratethanthebasalrate;therefore,foragivenvolume,thedoseisdeliveredfaster.
18 In some publications, the PIB is referred to as an “automated bolus” or “automated mandatory bolus.” This usage is less
common than PIB or PIEB.
