failure.
Ahardwareorother
fatalerrorhas
occurredinsidethe
wirelessmoduleor
themonitor.
TryanotherWSpO

module.Ifthefailure
persists,immediatelyremovethesystemfrom
serviceandcontactInvivoforrepair,asthe

INTRFERNCE
Thesignalqualityof
thelightchannelsis
inadequatefor
accuratesaturation
calculation.
Theprobelight
sourcemaynotbe
alignedwiththelight
receiver,orthe
probemaybepoorly
positioned.
•Checkthealignmentoftheprobe.
•Tryadifferentlimborsite.
•Tryusingadifferentprobe.
LOWPERFUSION
The
perfusion
measuredislow
enoughtocause
possible
inaccuraciesinthe
reportedsaturation
value.
Thetissueatthesite
maybetooopaque
and/orthick.
Ifthesensorispositionedonafinger,check
thefingernailfornailpolish,orlongor
artificialfingernails.Removefingernailpolish
completely.Forartificialnails,
tryanother
location(forexample,atoe).
NOPROBE
TheWSpO
2
module
detectsthatno
probeisconnected.
TheSpO
2
probeis
notconnected(oris
notproperly
connected)tothe
module.
Checkthe connectionoftheprobetothe
WSpO
2
module.Ifconnectionappearssound,
tryanotherprobe.
NON‐PULSAT
Non‐pulsatile
condition.
Checkthecondition
ofthepatient.
Thepatient’spulseis
tooweakforthe
systemtoreport
reliableSpO
2

saturationandpulse
measurements.
•Checktheprobepositionandalignmenton
thepatient,thenre‐positionorre‐applyas
necessary.
•Tryadifferentlimborsite.
NOISE
Patientmotionor
electrical
interferenceisbeing
experiencedbythe
SpO
2
system.
Excessivepatient
motionorelectrical
noise.
•Checkforpatientmotion,especiallyatthe
monitoredsite.
• Ensurethattheprobeispositionedsothat
thesensorsarenotexposedtoexcessive
levelsofambientlight.
PROBEOFF
Thesystemdetects
thattheprobeisnot
appliedtothe
patient.
TheSpO
2
sensoris
notproperlyapplied
tothepatient.
Checkprobepositionandalignmentonthe
patient,thenrepositionorreapplyitas
necessary.
PULSE?
TheSpO
2
‐derived
pulserateisoutside
thedetectable
range.
Theprobemaynot
beappliedoptimally
orthetissueatthe
appliedsitemaytoo
opaque.
•Checkthealignmentoftheprobe.
•Tryadifferentlimborsite.
