Precautions about SpO
2
Monitoring
WARNING
 For SpO
2
monitoring, use only the specified probe. Check the probe
before usage to make sure that it is the specified probe. If unspecified
probe is used, not only that the equipment cannot deliver its maximum
performance, the equipment may be damaged and safety cannot be
ensured.
 If the nail is rough, dirty, or manicured, accurate measurement will not
be possible. Change the finger or clean the nail before attaching the
sensor.
 If irritation such as skin reddening appears with the sensor use, change
the attachment site or stop using the sensor.
 Do not use a tape to attach the sensor.
 When the SpO
2
probe is disconnected from the equipment, the SpO
2
measurement/waveform will not be displayed on the receiving monitor.
Also, the alarms will not be generated. Make sure that the SpO
2
probe is
securely connected to this equipment.
 When not measuring, unplug the SpO
2
probe from the connector.
Otherwise, the outside light may affect to falsely display the
measurements.
 Check the sensor attachment site constantly every 4 hours when probes
or reusable sensor are used, and at least every 8 hours when single
patient use sensors are used. Be especially careful of a patient with bad
perfusion. If the sensor attachment position is not changed constantly,
skin irritation or skin necrosis due to compression may be developed.
For the patient with bad perfusion, check the sensor attachment position
at least every 2 hours.
 As skin for neonate, premature infant is immature, change the sensor
attachment site more frequently depending on the condition.
 When measuring the SpO
2
of patient with high fever or peripheral
circulatory insufficiency, check the sensor attachment periodically and
change the attachment site. The temperature of the attachment site will
rise due to the sensor heat which may result in burn injury.
 Even attachment for a short duration may inhibit the blood flow and
generate compression necrosis. Also, blood flow inhibition may prevent
correct measurements.
 Direct sunlight to the sensor area can cause a measurement error.
Place a black or dark cloth over the sensor if using in direct sunlight.
 The pulse wave is normalized for SpO
2
measurement, and does not
indicate perfused blood volume. Check proper sensor attachment by
observing the pulse wave.
 Precautions for Reusable Sensors
The light-emitting part of the sensor should be over the root of the
fingernail or as instructed per the related sensor instruction manual. Do
not insert the finger too far into the sensor as it may hurt the patient. For
details, refer to the SpO
2
sensor instruction manual.
 Precautions for Single-Patient-Use Type Sensors
The sensor can be reused on the same patient as long as the adhesive
tape attaches without slippage. Do not reuse on other patients to avoid
