PROBLEM TYPE SOLUTION
LOW PERFUSION
(PI BAR TURNS
RED)
Improper sensor type.
Poorly perfused site.
Sensor is too tight.
A disorder such as hypo-
thermia, vasoconstriction,
hypovolemia, peripheral
vascular disease or anemia.
Sensor is damaged.
Verify proper sensor and sensor size
for the patient.
Check and see if blood flow to the site
is restricted. Be sure that the sensor is
not on too tight.
Set unit to MAX sensitivity.
Warm the patient or sensor site.
Move sensor to better perfused site.
LOW SIGNAL
QUALITY
Improper sensor type or
application.
Excessive motion relative to
perfusion.
Sensor or cable 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 differ-
ent site.
Replace sensor or cable.
SpO2 VALUES DO
NOT CORRELATE
WITH CLINICAL
ASSESSMENT OR
ABGs.
Low perfusion
or sensor displacement.
Check for error messages. See section
5
Messages for recommended cor-
rections.
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.
Refer to sensor Directions For Use.
PULSE SEARCH
MESSAGE
Device is searching for pulse.
If device fails to display within 30 sec-
onds, disconnect and reconnect sensor
to patient. If pulse search continues,
move sensor to better perfused site.
UNEXPECTED
SpO2, SpCO, OR
SpMet 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 com-
parison.
Inappropriate sensor size
or sensor measurement
location.
Verify proper sensor for patient size.
Verify proper sensor site.
* Elevated methemoglobin levels may cause falsely elevated carboxyhemoglobin values.
