CHAPTER 12
Monitoring NIBP
TheNIBP(non‐invasivebloodpressure)parametermeasuresanddisplayssystolic,diastolicand
meanarterialpressures.Alarmlimitsettingsareavailableforallthreepressures.Whenusing
NIBPtomeasurebloodpressure,readingsarenotcontinuousbutareupdatedeachtimeablood
pressuremeasurementistaken.Setashorterinterval
whenfrequentupdatingofthepatient’s
bloodpressureisneeded.Visuallycheckingthepatient,confirmingNIBPmeasurementsagainst
othervitalsignmeasurementsandattentiontothelimbwherethecuffisattachedmustbe
standardroutinesduringNIBPuse.
Adultandpediatricbloodpressuremeasurementsdeterminedwiththisdeviceare
equivalentto
thoseobtainedbyatrainedobserverusingthecuff/stethoscopeauscultatorymethod,withinthe
limitsprescribedbytheAmericanNationalStandard, manual,electronic,orautomated
sphygmomanometers.
Thismonitorusestheoscillometricmethodformeasuring NIBP.Studiesshowthat,especiallyin
criticalcases(arrhythmia,vasoconstriction,hypertension,shock),oscillometricdevicesaremore

accurateandconsistentthandevicesusingothernoninvasivemeasuringtechniques.
Inadultandpediatricmode,thebloodpressuremeasurementsdeterminedwith thisdevice
complywiththeAmericanNationalStandardforElectronicorAutomatedSphygmomanometers
(IEC80601‐2‐30:2011)inrelationtomeanerrorandstandarddeviation,whencomparedtointra‐
arterial
orauscultatorymeasurements(dependingontheconfiguration)inarepresentative
patientpopulation.Fortheauscultatoryreference,thefifthKorotkoffsoundwasusedto
determinethediastolicpressure.
Inneonatalmode,thebloodpres suremeasurementsdeterminedwiththisdevicecomplywith
theAmericanNationalStandardforElectronicorAutomatedSphygmomanometers(IEC
80601‐2‐
30:2011)inrelationtomeanerrorandstandarddeviation, whencomparedtointra‐arterial
measurementsinarepresentativepatientpopulation.Neonatalbloodpressuremeasurements
determinedwiththisdeviceareequivalenttothoseobtainedbyanintra‐arterialbloodpressure
measurementdevice,withinthelimitsprescribedbytheAmericanNational
Standard,manual,
electronic,orautomatedsphygmomanometers.
WARNINGS
• Use clinical judgment to decide whether to perform a repeated series of NIBP
measurements because of the risk of purpura, ischemia and neuropathy in the limb
with the NIBP cuff.
• Arrhythmias, erratic heartbeats and patient motion can result in inaccurate readings
and/or prolonged measurements. If questionable readings are obtained, check the
patient’s vital signs by alternate means before administering medication.
• The performance of the automated sphygmomanometer can be affected by extremes of
temperature, humidity and altitude.
