3.2.1 PCAMode
PCAmodeallowsforbolus-only,basal-onlyorboluswithbasalowrates.

• Thebasalowrateisthecontinuousowrate.Itoccurswhenthepump
isnotdeliveringabolusinPCAmode.Thebasalowrateisadjustable
and has units of milliliters per hour (ml/hr).
• A bolus is a volume of medication infused over a relatively short period
of time.
16
Thebolusisinfusedatthebolusow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ow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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.
• The lockout time is 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).
• PCA is an acronym for patient-controlled analgesia. If a pump is in PCA
mode and the patient has been prescribed a bolus volume, the PCA
mode allows for the user to periodically request a bolus of medication. If
the infusion is into the epidural space the PCA is referred to as patient-
controlled epidural analgesia (PCEA).
• 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 in PCA mode, if the tens and/or ones digits are already
set to the desired setting, press the RUN/ PAUSE button 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patternsofowavailableinPCAmode;specically,
bolus-only,basal-only,andboluswithbasalowrates(Figures1-1through1-3).
16 Thebolusisdeliveredatahigherowratethanthebasalrate;therefore,foragivenvolume,thebolusisdeliveredfaster.
