Chapter 8 SpO
SpO
is based on the absorption of pulse blood oxygen to red and infrared light by means of
2
finger sensor and SpO
determine the oxygen saturation of hemoglobin in the arterial blood. The SpO
provide a pulse rate (PR) and a plethysmogram wave (Pleth).
8.1 Safety Information
1
Do not use the SpO

2
If the SpO
sensor cannot work properly, please reconnect the sensor or change a

new one.

Correct and proper sensor application: if the sensor is too loose, it might compromise
the optical alignment, and even cause the sensor to fall off. If the sensor is too tight,
(such as the application site is too large or becomes too large due to edema),
excessive pressure and local tissue ischemia, hypoxia and lack of nutrition may occur
on the application site. Prolonged and continuous monitoring may increase the risk of
Skin irritations or lacerations. To avoid these damages, users should periodically
check surrounding skin of application site according to the patient's condition and
pressure sensor, inspect the if there is sign of stress-related damage in surrounding
tissue, and regularly change the application site. For the patients whose fluid is easy
to transfer and/or the patients with systemic or localized edema, users should inspect
the skin and change application site more frequently.
4
Use only EDAN permitted sensors and extension cables with the monitor. Other
sensors or extension cables may cause improper monitor performance and/or minor
personal injury.
5
High oxygen levels may predispose a premature infant to retrolental fibroplasia. If this
is a consideration do NOT set the high alarm limit to 100%, which is equivalent to
switching the high limit alarm off.

NOTE:
1
Avoid placing the sensor on extremities with an arterial catheter, or intravascular
venous infusion line.
2
When a trend toward patient deoxygenation is indicated, analyze the blood samples
with a laboratory co-oximeter to completely understand the patient's condition.
