Low Perfusion
It has been suggested that at extremely low perfusion levels, pulse
oximeters can measure peripheral saturation, which may differ from
central arterial saturation This "localized hypoxemia" may result from the
metabolic demands of other tissues extracting oxygen proximal to the
monitoring site under conditions of sustained peripheral hypoperfusion.
This may occur even with a pulse rate that correlates with the ECG heart
rate.
Low Signal Quality
Improper sensor type or application.
Next steps: 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. Reapply sensor or move to a different
site. See
Appendix
on page 209.
SpO2 Values Do Not Correlate With Clinical Assessment or
Arterial Blood Gas Measurements
Low perfusion or sensor displacement.
Next steps: Check for error messages. See
Chapter 6: Alarms and
Messages
on page 153. 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. See the directions for use
provided with your sensor.
