Safety Information
WARNING
1 Do not use the SpO
2
sensors if the packaging or the sensor is damaged and return
them to the vendor.
2 If the SpO
2
sensor cannot work properly, please reconnect the sensor or change a
new one.
3 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.
