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 electrosurgical unit.
• During CPR.
• When measuring at a site with venous pulse.
• When there is body movement.
• When the pulse wave is small (insufficient peripheral circulation).
• When using an electrosurgical unit.
• During CPR.
• When measuring at a site with venous pulse.
• When there is body movement.
• When the pulse wave is small (insufficient peripheral circulation).
• Check the circulation condition by observing the skin color of the measuring
site and pulse waveform. Change the measuring site every 8 hours for
disposable probes and every 4 hours for reusable probes. The skin
temperature may increase at the attached site by 2 or 3°C (4 or 5°F) and
cause a burn or pressure necrosis. When using the probe on the following
patients, take extreme care and change the measurement site more
frequently according to symptoms and degree.

• When using the TL-201T finger probe, do not fasten the probe and cable to the
finger by wrapping with tape. This may cause burn, congestion or pressure
necrosis from poor blood circulation.
necrosis from poor blood circulation.
• When using probes other than the TL-201T finger probe, to avoid poor
circulation, do not wrap the tape too tight. 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, especially on neonates or
low birth weight infants whose skin is delicate. Accurate measurement cannot
be performed on a site with poor peripheral circulation.
