If the message "SpO
2
Low Perf." or "SpO
2
Weak Pulse" displays, check sensor
application, re-apply or remove the sensor if necessary, to obtain a better
signal.

A function tester or SpO
2
simulator can be used to verify the sensor functions.

A functional tester or SpO
2
simulator cannot be used to assess the accuracy of a
SpO
2
module or a SpO
2
sensor.

A functional tester or SpO
2
simulator can be used to determine the pulse rate
accuracy.
7.2 Safety
WARNING

Use only SpO
2
sensors specified in this manual. Follow the SpO
2
sensor’s
instructions for use and adhere to all warnings and cautions.

When a trend toward patient deoxygenation is indicated, blood samples should
be analyzed by a laboratory co-oximeter to completely understand the patient’s
condition.

Do not use SpO
2
sensors during magnetic resonance imaging (MRI). Induced
current could potentially cause burns. The sensor may affect the MRI image,
and the MRI unit may affect the accuracy of the oximetry measurements.

Prolonged continuous monitoring may increase the risk of undesirable changes
in skin characteristics, such as irritation, reddening, blistering or burns. Inspect
the sensor site every two hours and move the sensor if the skin quality changes.
Change the application site every four hours. For neonates, or patients with
poor peripheral blood circulation or sensitive skin, inspect the sensor site more
frequently.
7.3 Identifying SpO
