Measurement
• Do not shake or swing the electrode junction box holding the cable or
EEG lead connected to the electrode junction box. The electrode
junction box may come off and it may injure somebody or damage
surrounding instruments.
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)
• 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.
• 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 not measuring SpO
2
, disconnect the SpO
2
adapter cable from
the telemetry unit. Otherwise, noise from the probe sensor may
interfere and incorrect data is displayed on the screen.
