Monitoring SPO2
ThepulseoximetryfeatureoftheMR400usesamotion‐tolerantsignalprocessingalgorithm
basedonFourierArtifactSuppressionTechnology(FAST)andiscalibratedtodisplayoxygenated
hemoglobinmeasurements,avisualpulseindicationandapulserate,specifically:
•Oxygensaturationofarterialblood(SPO2):Thepercentageofoxygenatedhemoglobinin
relation
tothesumofoxyhemoglobinanddeoxyhemog lobin(functionalarterialoxygen
saturation).
• Plethysmography(pleth)waveform:Avisualindicationofthepatient’spulsatileblood
flow.
•Pulserate(asderivedfromtheplethwaveform):Thenumberofdetectedpulsationsper
minute.
•Perfusionindexvalue–Anumericalindicationofthepulsatileportionofthemeasured
signalcausedbyarterialpulsation.
CAUTION
Before use, verify that the wSpO2 module is operating correctly and communicating by checking
the displayed SPO2 numeric and waveform. Also, ensure that the wSpO2 module has a
sufficiently charged battery by checking its displayed status symbol; see page 2-16.
Note
A pulse oximeter should be considered an early warning device. As a trend toward patient
deoxygenation is indicated, blood samples must be analyzed by a laboratory co-oximeter to
understand the patient’s condition completely.
wSpO2 Module, SpO2 Probe and SpO2 Attachment
ThewSpO2module,SpO2probeandSpO2attachment(cliporgrip)areintendedforpatientuses
whennon‐invasivearterialoxygensaturation,pulseratemonitoringorpulsegatingarerequired.
ThewSpO2module,SpO2probeandSpO2attachmentmaynotbeusedwithintheMRsystem
bore.
