WARNINGS!
• Change the measured finger regularly according to the
patient's conditions after prolonged use. It must be moved
every 4 hours or more often and reapplied to another site
according to the user’s skin integrity and circulatory status.
• Excessive ambient light, excessive motion, use of
intravascular dyes, poorly perfused finger, extreme finger
sizes or improper placement may affect the accuracy of the
measurement.
• Nail polish or false nails may cause erroneous measurement
results.
• Overly low blood pressure, overly low systolic blood pressure,
severe anemia, or hypothermia may cause erroneous
measurement results.
• The pulse oximeter sensor is designed for use with this
device only.
• Check the compatibility of the device and pulse oximeter
sensor before use; otherwise it may cause injury to the
patient.
• A functional tester cannot be used to assess the accuracy of
the SpO

measurement result.
• Do not use the pulse oximeter sensor during MRI scanning.
• Do not use a broken pulse oximeter sensor.
• Do not immerse the pulse oximeter sensor in liquid, as it
causes short circuit.
• The pulse oximeter sensor may not work on cold extremities
due to reduced circulation. Warm or rub the finger to increase
circulation, or reposition the sensor.
• If the pulse oximeter sensor is shared by multi-users, the
users may be exposed to the risk of cross-infection.
• Blood flow must not be impeded during the recording process.
The pulse oximeter sensor should be applied snug and
comfortable, but not too tight or subject to any excessive
pressure.
