Pulse Oximeter
General Description
Oxygen Saturation is a percentage of Oxyhemoglobin (HbO
2
) capacity,
compounded with oxygen, by all combinative hemoglobin (Hb) capacity in
blood. In other words, it is consistency of Oxyhemoglobin in blood. It is a
very important parameter for the Respiratory Circulation System. Many
respiratory diseases can result in oxygen saturation being lowered in
human blood. Additionally, the following factors can reduce oxygen
saturation: Automatic regulation of organ dysfunction caused by
Anesthesia, Intensive Postoperative Trauma, injuries caused by some
medical examinations. That situation might result in light-headedness,
asthenia, and vomiting. Therefore, it is very important to know the oxygen
saturation of a user so that doctors can find problems in a timely manner.
The fingertip pulse Oximeter features small size, low power consumption,
convenient operation and portability. It is only necessary for a user to put
one of his fingers into the fingertip photoelectric sensor for diagnosis, and a
display screen will show oxygen saturation. It has been proven in clinical
experiments that it also features high precision and repeatability.
Measurement principle
Principle of the Oximeter is as follows: A mathematical formula is
established making use of Lambert Beer Law according to Spectrum
Absorption Characteristics of Reductive hemoglobin(RHb) and
Oxyhemoglobin (HbO
2
) in glow and near-infrared zones. Operation
principle of the instrument: Photoelectric Oxyhemoglobin Inspection
Technology is adopted in accordance with Capacity Pulse Scanning and
Recording Technology, so that two beams of different wavelength of lights
(660nm glow and 940nm near infrared light) can be focused onto a human
nail tip through a clamping finger-type sensor. A measured signal obtained
by a photosensitive element, will be shown on the Oximeter’s display
through process in electronic circuits and microprocessor shown on the
Oximeter’s display through electronic circuits and a microprocessor.

Precautions for use
1
Do not use the pulse oximeter in an MRI or CT environment
2
Do not use the pulse oximeter in situations where alarms are required.
The device has no alarms.
3 Explosion hazard:
Do not use the pulse oximeter in an explosive
atmosphere.
4
The pulse oximeter is intended only as an adjunct in user assessment. It
must be used in conjunction with other methods of assessing clinical
signs and symptoms.
5
Check the pulse oximeter sensor application site frequently to determine
the positioning of the sensor and circulation and skin sensitivity of the
user.
6
Do not stretch the adhesive tape while applying the pulse oximeter
sensor. This may cause inaccurate readings or skin blisters.
7
Before use, carefully read the manual.
8
The pulse oximeter has no SPO
2
alarms; it is not for continuous
monitoring.
9
Prolonged use or the user’s condition may require changing the sensor
site periodically. Change sensor site and check skin integrity, circulatory
status, and correct alignment at least every 4 hours.
10
Inaccurate measurements may be caused by autoclaving, ethylene
oxide sterilizing, or immersing the sensors in liquid.
11
Significant levels of dysfunctional hemoglobins (such as carbonxy-
hemoglobin or methemoglobin) may cause inaccurate readings.
12
Intravascular dyes such as indocyanine green or methylene blue.
13
SPO
2
measurements may be adversely affected in the presence of high
ambient light. Shield the sensor area (with a surgical towel, or direct
sunlight, for example) if necessary.
14
Excessive user movement may cause inaccurate readings.
15
Venous pulsations may cause inaccurate readings.
16
High-frequency electrosurgical interference may cause inaccurate
readings.
17
Placement of a sensor on an extremity with a blood pressure cuff,
arterial catheter, or intravascular line.
18
The user has hypotension, severe vasoconstriction, severe anemia, or
hypothermia.
19
The user is in cardiac arrest or is in shock.
20
Fingernail polish or false fingernails may cause inaccurate SPO
2
readings.
Follow local ordinances and recycling instructions regarding
disposal or recycling of the device and device components, including
batteries.
Product Properties
1 Operation of the product is simple and convenient
2 The product is small in volume, light in weight and convenient in
carrying.
3 Power consumption of the product is low and the two AAA batteries can
be operated continuously for 24 hours.
4 A low voltage warning will be indicated in visual window when battery
voltage is so low that normal operation of the oximeter might be
influenced.
5 The product will automatically be powered off when no signal is in the
product for longer than 16 seconds.
Product Operation Scope
Fingertip PULSE OXIMETER is a portable non-invasive, spot-check,
oxygen saturation of arterial hemoglobin (SPO
2
) and pulse rate of adult
and pediatric user at home, and hospital (including clinical use in
internist/surgery, Anesthesia, intensive care etc). It is not for continuously
monitoring.
Operation Instructions
1 Install two AAA batteries into battery compartment correctly.
2 Place clamp over finger nail as the following diagram.
3 Insert one finger into rubber hole of the Oximeter fully.
4 Press the switch once on the front panel.
5 Finger and body should not tremble during measuring.
6 Read correct data from display screen.
After turn on the oximeter, each time you press the function button, the
oximeter will switch to another display mode, there are 4 display modes
totally.
Long press the function button to enter the settings screen.
Short press to switch among the settings, long press to change the
current settings of sounds and alarm limits.
Notes:
When your finger insert into the Oximeter, your nail surface must be
upward.
The results may be wrong if you did not plug the finger thoroughly in the
Oximeter.
Please use medical alcohol to clean the rubber touching the finger inside
of Oximeter, and clean the test finger using alcohol before and after each
test. (The rubber inside of the Oximeter belongs medical rubber, which
has no toxin and no harmful to the skin).
Brief Description of Front Panel
The Pulse bar graph displays corrernding with the user’s pulse beat. The
height of the bar graph shows the user’s pulse strength.
