Overview
Oxygen saturation is the percentage of oxyhemoglobin (HbO2) that is combined with oxygen
against all combinable hemoglobin (Hb). It is an important physiological parameter involved in
respiration and circulation. The oxygen saturation of arterial blood in a normal human body is
98%. Oxygen saturation is an important indicator of the oxygen condition in the human body. In
general, the normal values of oxygen saturation shall not be lower than 94%. If the measured
value of oxygen saturation is lower than 94%, an insufficient supply of oxygen is considered.
The pulse rate is the number of pulse beats per minute. Normally, the pulse rate is consistent with
the heart rate. In general, the pulse rate of every people is 60 to 90 beats per minute.
The Perfusion Index (PI) usually reflects the limb perfusion status of an examined patient, and
shows the detection precision of the instrument as well; that is, examination can still be
performed even in the low or weak perfusion condition.The PI of a normal human body is 3% or
greater.
Working Principles, Expected Usage, and Applicable Scope
Based on full digital technology, the Finger Pulse Oximeter non-invasively measures the actual
content (oxygen saturation) of oxyhemoglobin (HbO2) in arterial blood using the optical
transmittance method.
The Finger Pulse Oximeter measures the blood oxygen saturation and pulse rate of a human body
via finger artery. It is applicable to a wide range of fields, such as families, clinics. Use this
instrument for measurement before or after sports. You are not advised to use this instrument
during sports activities. Do not use it for continuous care for patients.

The following figure shows the information display on the OLED screen of the Oximeter in
normal detection state:
Power-On Button/Functional Button Operations
After powering on the Oximeter, hold the power-on Button/functional button for about one
second. The Oximeter shows a parameter setting interface. Press or hold the power-on/functional
button to perform corresponding operations. Hold it to set an item, Press means no more than 0.5
seconds, while Hold means more than 0.5 seconds.
Alert Sound Setting
Hold the power-on button/functional button while the Oximeter is in powered-on state. Parameter
setting interface 1 is displayed, as shown in the following figure. Move "*" to the corresponding
option, and hold the functional button to set Alm to on and set Beep to off. When Alm is set to
