How to Read the Measurement Values
Pulse level meter: Indicates the pulse level in 8 levels (0 to 10%, full
scale if 10% or higher). The pulse level is defined as follows. (For sta-
ble measurements, adjust the measuring point of the finger holder or
rub or warm the measuring point to improve blood circulation, so that
the pulse level meter constantly indicates level 2 or higher.)
Pulse level (%) = Variable transmittance × 100
Constant transmittance
Calculation method for displayed values
Oxygen saturation value (SpO2):
Value obtained by performing moving averaging for the last
5 seconds is updated and displayed every second.
Pulse rate (P.R.):
Value obtained by performing moving averaging for the last
8 pulse rates is updated and displayed every second.
Battery indication: The battery mark will begin to
blink when the battery power

Error Messages
The Measure-
ment Value and
flash alternately
Cause Solution
• Insufficient light for
measurement..
• Strong light enters the
finger holder’s sensor
directory.
• Pulse signal required
for measurement is
not being received.
• The pulse is weak and
the pulse signals
required for the meas-
urement are not ob-
tained. The measure-
ment value is dis-
played, however, the
accuracy of the meas-
urement values can
not be guaranteed.
Thus, the measured
value must be consid-
ered as guidance
only.
• Check that the finger holder is properly
attached to the patient.
• Clean the light-source and sensor
sections.
• Take measures to prevent direct entry
of strong light to the finger holder.
• Check that the finger holder is properly
attached to the patient. If the finger
holder is properly attached but this
message still appears, the circulation in
the area being measured may not be
good. If this occurs, warm up the
measurement location.
• Attach the finger holder to the body
correctly. If this message is displayed
when the unit is attached to the patient
correctly, the measurement conditions
are regarded as blood circulation or
other circulatory problems. If this
occurs, warm up the measurement
locations.
• In particular, when the pulse is weak,
this error tends to occur. For improved
measurement accuracy, if the finger
holder is exposed to strong light, wrap it
with a piece of black cloth, etc. Also
make sure that the patient rests calmly
to avoid influence of body movement.

11. REFERENCE
Measurement Principle
Oxygen Saturation Monitor PULSOX-2 is a photometric instrument that
non-invasively and continuously measures the oxyhemoglobin satura-
tion of arterial blood (SpO2) and the pulse rate. SpO2 is described by
the equation:
SpO2 = C (HbO2) × 100 (% SpO2)
C (HbO2) + C (Hb)
where
C (Hb): Concentration of reduced hemoglobin
C (HbO2): Concentration of oxyhemoglobin
The light-absorption characteristics of reduced hemoglobin (Hb) are
very different from those of oxyhemoglobin. The PULSOX-2 meas-
ures the changes in the absorption of red and infrared lights passing
through the tissue to determine the SpO2 of the blood. Thus, this
method is free from the effects of skin color, muscles, bones, and
veins.
