PROBLEM POSSIBLE CAUSE(S) RECOMMENDATION

LOW SIGNAL QUALITY

Improper sensor type or

application.

Excessive motion relative

to perfusion.

Sensor is damaged or not

functioning.

Check and see if blood flow to the

site is restricted.

Check the placement of the sensor.

Re-apply sensor or move to a

different site.

SpO

VALUES DO NOT

CORRELATE WITH

CLINICAL ASSESSMENT

OR ABGs

Low perfusion or sensor

displacement.

Check for error messages. See

section 5 System Messages for

recommended corrections.

Check placement of sensor or if it is

too tight. Reapply sensor or select a

new site.

Set to MAX sensitivity and confirm that

the sensor is securely on the patient.

pulse.

If instrument fails to display within 30

seconds, disconnect and reconnect. If

pulse search continues, move sensor

to better perfused site.

UNEXPECTED SpO

SpCO, SpMet OR SpHb

READING

Low SIQ or Perfusion Index

(PI) values.

Reposition sensor to site with strong

SIQ and PI. Average readings taken

from three different sites to improve

accuracy. Submit blood sample for

laboratory CO-Oximetry test for

comparison.

Inappropriate sensor size

or sensor measurement

location.

Verify proper sensor for patient size.

Verify proper sensor site.

UNEXPECTEDLY HIGH

SpCO READING

Possible elevated

methemoglobin level.

Submit blood sample for laboratory

CO-Oximetry test.

DIFFICULTY OR NO SpCO/

SpMet/SpHb READING

Low battery/ not plugged

into AC power supply.

Insert handheld into docking station,

verify docking station power cord

plugged in and docking station power

indicator light is illuminated.

Interference from line-

frequency induced noise.

Verify/set 50/60hz menu setting. Refer

Inappropriate sensor or

sensor size.

Verify proper sensor and sensor size

for the patient.

Excessive ambient or

strobing light.
