Physiological Alarm Violations
Physiologicalalarmsreceivethehighestpriorityreportingstatus.Aphysiologicalalarmisviolated
whenapatientparameter(SpO
2
orheartrate)exceedsthehighorlowsettingofthe
correspondingalarmlimit.Thereactionofthesystemtoaphysiologicalalarmdependsuponthe
settingsdescribedbelowandgenerallyasfollows:
a. Thealarmlightflashesred (seeillustration below).
b. IfSpO
2
related,aredwaveformisdisplayed.
c. Thenumericoftheviolatedparameterflashesred.
d. Thehighpriorityalarmtonesounds‐‐atahighpitch‐‐5pulsetonesfollowedbya1
seconddelaythen5pulsetones,repeatingevery5seconds.
e. Thenumericcontinuestoflashwhiletheparameterviolatesitsalarm
limit,evenafter
thealarmtonehasbeenmutedbytouchingtheAlarmsSilencebutton.
f. Ifthenumericexceedsthehighestvaluethatcanbedisplayed,OVRwillbeindicated
intheparameternumeric.
g. Thenumericstopsflashingaftertheparameterreturnstowithinitsalarmlimits.
h. Thedisplayednumericof
theviolatedparameterflashesandtheaudiblealarm,once
silenced,willnotsoundagainuntilthealarmconditionhasbeencorrectedandre‐
violated.Onlyaseconddifferentparameteralarmwillcausethealarmsoundand
alarmlighttoreactivate.
Example,visualphysiologicalalarmindicators:
Physiologicalalarmtestingcanbeperformedusing
apatientSpO
2
simulatortoexceedan
individualalarmlimit.Alarmtestingcanalsobeperformedusingthemonitor’sDemomode
whereanindividualparameteralarmlimitcanbeadjusted‐‐ahighlimitsetbelowthesimulated
numericoralowlimitsetabovethesimulatednumeric(exceptSpO
2
)‐‐totriggeraphysiological
alarm.Ifaproblemwiththealarmtoneormessagesystemissuspected,thissystemmustbe
referredtoanInvivo‐authorizedservicepersonnelforevaluation.
