Alarms
Thealarminformationhereappliestoallmeasurements.Measurement‐specificalarm
informationisdiscussedinthesectionsonindividualmeasurements.Themonitorprovides
patientalarmsandINOPalarms.
PatientAlarms
Patientalarmswi ll illuminatearedoryellowalarmlight,wherearedalarmlightindicatesahigh
priorityalarmtoalert
youtopotentiallylifethreateningsituationsforyourpatient(forexample,
adisconnectedcatheter).Ayellowalarmlightindicatesalowerprioritypatientalarm(for
example,arespirationalarmlimitviolation).
Patientalarmsmayalsogenerateflashingnumericvaluesorotherindications,alarmflagsand
soundanaudiblealarm(provided
thatahigherpriorityalarmsounddoesnotoverride it).
Forexample,ifapatient’sheartrateclimbs to71BPM(whichisabovethesettingoftheupper
alarmlimit)aphysiologicalalarmconditionisdeclared.
INOPs
INOPsarestatusandtechnicalalarms—theyindicatethatthemonitorcannotmeasureordetect
alarmconditionsreliably;seepage4‐31foralisting.Dependinguponthenatureofthecondition
detected,INOPswillilluminatethealarmlig ht,generateanalarmflag,andsoundanaudible
indicatortone(providedthatahigherpriorityalarmsounddoesnotoverrideit).Otherstatus
andtechnicalalarmshave
amediumorhighprioritydependinguponthenatureofthecondition
detected.
MultipleAlarms
Patientalarmsaremutuallyexclusiveandthehighestpriorityalarmwillbeindicatedbythealarm
light;ifahighpriorityalarmandamediumpriorityalarmarepresentsimultaneously.thered
alarmlightwillbe
on,buttheyellowalarmlightwillnotbe.
