WARNING
 This equipment may be used during electrocautery, but this may affect
the accuracy or availability of the SpO
2
parameters and measurements.
 The SpO
2
data cannot be used for arrhythmia analysis.
 SpO
2
is empirically calibrated in healthy adult volunteers with normal
levels of carboxyhemoglobin (COHb) and methemoglobin (MetHb).
 Do not adjust, repair, open, disassemble, or modify this equipment or
accessories. Injury to personnel or equipment damage could occur.
Return this equipment for servicing if necessary.
CAUTION
 SpO
2
sensors are not waterproof. Keep away from liquids.
 Do not pick up the equipment pulling the sensor or cable part. It may get
disconnected from the equipment and the equipment may be dropped.
 “SpO
2
OFF” is displayed when the SpO
2
measurement is turned OFF.
 A message is displayed when the SpO
2
sensor is disconnected from the
equipment.
 A message is displayed when the equipment detects that the SpO
2
sensor is disconnected from the patient. Properly attach the SpO
2
sensor
to the patient.
 Do not reuse the single-use SpO
2
sensor. It may cause incorrect
measurements.
 Read through the instruction of the SpO
2
sensor as well.
 Do not place this equipment where the controls can be changed by the
patient.
 Electrical shock and flammability hazard: Before cleaning this
equipment, make sure to turn off the power.
 When patients are undergoing photodynamic therapy, they may be
sensitive to light sources. Pulse oximetry may be used only under
careful clinical supervision for short time periods to minimize interference
with photodynamic therapy.
 Do not place this equipment on electrical equipment that may affect the
operation, preventing it from working properly.
 If the measurements indicate hypoxemia, a laboratory blood sample
should be taken to accurately assess the patient’s condition.
 If the <LowPerf.> message is frequently displayed, find a better perfused
monitoring site. In the interim, assess the patient and, if indicated, verify
oxygenation status through other means.
 Change the application site or replace the sensor when a < Bad Sens >
is displayed on the monitor. This messages may indicate that patient
monitoring time is exhausted on the patient sensor.
 If using this equipment during full body irradiation, keep the sensor out of
the radiation field. If the sensor is exposed to the radiation, the reading
might be inaccurate or the equipment might read zero for the duration of
the active irradiation period.
 Variation in hemoglobin measurements may be profound and may be
affected by sampling technique as well as the patient's physiological
conditions. Any results exhibiting inconsistency with the patient’s clinical
