Chapter 10 Monitoring SpO
2
10.1 Overview
SpO
2
is based on the absorption of pulse blood oxygen to red and infrared light by means of
finger sensor and SpO
2
measuring unit. SpO
2
Plethysmogram measurement is employed to
determine the oxygen saturation of hemoglobin in the arterial blood. If, for example, 97% of the
hemoglobin molecules in the red blood cells of the arterial blood combine with oxygen, then the
blood has a SpO
2
oxygen saturation of 97%. The SpO
2
numeric on the monitor will read 97%.
The SpO
2
numeric shows the percentage of hemoglobin molecules which have combined with
oxygen molecules to form oxyhemoglobin. The SpO
2
/PLETH parameter can also provide a pulse
rate signal and a plethysmogram wave.

Safety Information
WARNING
1
If the SpO
2
sensor can not work properly, please reconnect the sensor or change a
new one.
2
Do not use the sterile supplied SpO
2
sensors if the packaging or the sensor is
damaged and return them to the vendor.
3
Prolonged and continuous monitoring may increase the risk of unexpected change of
dermal condition such as abnormal sensitivity, rubescence, vesicle, repressive
putrescence, and so on. It is especially important to check the sensor placement of
neonate and patient of poor perfusion or immature dermogram by light collimation and
proper attaching strictly according to changes of the skin. More frequent examinations
may be required for different patients.
4
Tissue damage may be caused by incorrect application or prolonged measurement
duration using the sensor (more than 4 hours). Inspect the sensor periodically
according to the sensor user manual.
5
Neonate SpO
2
sensor can only be used when required, no more than 20 min at a
time.
6
Use only EDAN permitted sensors and extension cables with the moniter. Other
sensors or extension cables may cause improper monitor performance and/or minor
personal injury.
NOTE:
1
Make sure the nail covers the light window. The wire should be on the backside of the
hand.
2
SpO
2
waveform is not proportional to the pulse volume.
3
Avoid placing the sensor on extremities with an arterial catheter, or intravascular
venous infusion line.
