12.3.2 Precautions
WARNING
•
Pulse oximeter can overestimate the SpO2 value in the presence of Hb-CO,
Met-Hb or dye dilution chemicals.
•
ES (Electrosurgery) equipment wire and SpO2 cable must not be tangled up.
Carefully route patient cabling to reduce the possibility of patient entanglement
or strangulation.
•
Do not use this instrument and the sensors during magnetic resonance imaging
(MRI). Induced current could potentially cause burns. The monitor may affect
the MRI image, and the MRI unit may affect the accuracy of the oximetry
measurements.
•
Do not use the supplied sterile SpO2 sensors if the packaging or the sensor is
damaged. Return them to the distributor or manufacturer.
•
Before performing the testing, check the sensor cable. After unplugging the
SpO2 sensor cable from the socket, the system shall display the prompt
information "SPO2 SENSOR OFF" and give the audible alarm.
