caster feet. Do not immerse the probe cable in detergents or water. Failure to
follow these cautions may cause cable discontinuity, short circuit, skin burn
on the patient and incorrect measurement data. Replace any broken probe
with a new one.
• When the probe is attached on an appropriate site with sufficient circulation
and the error message confirming the probe attachment repeatedly appears,
the probe may be deteriorated. Replace it with a new one.
• When the probe failure message appears on the screen, replace it with a new
one. Otherwise SpO
2
data may not be accurate.
• While a patient is on medication which causes vasodilation, the pulse
waveform may change and in rare cases the SpO
2
value may not be displayed.
NOTE
In order to maintain sufficient blood circulation, keep the measurement site
warm by covering it with a blanket or something similar. Warming the site is
effective, especially for a patient with a small pulse amplitude.
SpO
2
and PR Display Order
You can select the display order for SpO
2
and PR (pulse rate) on the LCD. Refer to the
“Changing Parameter Setup Settings” section.
Monitoring SpO
2
during NIBP Measurement
When the SpO
2
probe is attached to the same limb as the NIBP cuff, the blood flow decreases
during NIBP measurement and pulse wave cannot be detected and SpO
2
cannot be monitored
properly. When “INHIBIT SpO
2
DURING NIBP” on the PARAMETER SETUP screen is set
to ON (factory default setting), SpO
2
monitoring is paused during NIBP measurement to avoid
SpO
2
alarm occurrence. However, when monitoring SpO
2
on the same limb as NIBP, be careful
when reading SpO
2
values.
When monitoring SpO
2
is important, attach the probe to the limb to which the NIBP cuff or
catheter is not attached.
When SpO
2
monitoring is paused during NIBP measurement, the SpO
2
value just before the
start of NIBP measurement and an
mark are displayed on the transmitter for 30 seconds.
When NIBP measurement is not completed after 30 seconds, “– – –” is displayed for the SpO
2
value. The same data also appears on the monitor screen.
