and photo detector of the probe face each other at the attachment site.
WARNING
• 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.
• 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.
WARNING
Check the circulation condition by
observing the skin color at the
measurement site and pulse waveform.
Change the measurement site every 8
hours for disposable probes and every
4 hours for reusable probes (every 8
hours for TL-631T series probe). 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.
• Patient with a fever
• Patient with insufficient peripheral
circulation
• Neonate or low birth weight infant
with delicate skin
WARNING
When monitoring SpO
2
of a patient
who is receiving photodynamic therapy,
the light from the finger probe sensor
may cause a burn. Photodynamic
therapy uses a photosensitizing agent
that has a side effect of
photosensitivity.
