3. EEG/PSG MEASUREMENT
Operator's Manual WEE-1000 3.17
Oxygen Saturation (SpO2)
The oxygen saturation is measured from the finger or earlobe with the SpO
2
probe
manufactured by Ninon Medical Inc. through the JL-101A SpO
2
Adapter.
WARNING
• Measurement may be incorrect in the following cases.
- When the patient’s carboxyhemoglobin or methemoglobin
increases abnormally
- When dye is injected in the blood
- When using an electrical surgery unit
- During CPR
- When there is body movement
- When there is vibration
- When measuring at a site with venous pulse
- When the pulse wave is small (insufficient peripheral circulation)
- When using an IABP (intra-aortic balloon pump)
• To avoid poor circulation, do not wrap the tape too tight when fixing
the probe with surgical tape. Check the blood circulation condition
by observing the skin color and congestion at the skin peripheral to
the probe attachment site. Even for short-term monitoring, there
may be burn or pressure necrosis from poor blood circulation.
• When using the probe on the following patients, take extreme care
and change the measurement site more frequently according to
symptoms and degree.
- A patient with a fever
- A patient with a peripheral circulation insufficiency
- Neonate or low birth weight infant with delicate skin
For a patient with a peripheral circulation insufficiency, the
measurement result may be incorrect.
• When the SpO
2
probe is used on a neonate, low birth weight infant or
patient with a fever or peripheral circulation insufficiency, a slight
burn may result from the probe increasing the skin temperature at
the attached site by 2 or 3°C (4 or 5°F). Periodically check the
attached state of the probe and change the attachment site.
• When not measuring SpO
2
, disconnect the SpO
2
adapter cable from
the telemetry unit. Otherwise, noise from the SpO
2
probe may
interfere and incorrect data is displayed on the screen.
CAUTION
• Only use the specified probes and JL-101A SpO
2
Adapter. Otherwise
SpO
2
cannot be monitored properly and instrument performance may
be degraded.
• Do not use a probe which is past the expiration date on the package.
• Do not use a damaged or disassembled probe.
• Disposable probes are not sterilized.
