Section 1 Intended Use and Safety
1.1 Intended Use
This product is suitable for the hospital (including surgey, anedthesiology,
paediatrics, and clinical use), oxygen bar, sports health(using them before or
after sports, do not advise using them during the movement), and community
health care, ect.
1.2 Instructions for the Safe Operation and Use of the Pulse Oximeter
⚫
Do not attempt to service the pulse oximeter. Only qualified service
personnel should attempt any needed internal servicing.
⚫
Do not use the oximeter in situations where alarms are required.
⚫
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 every hour.
⚫
SpO2 measurements may be adversely affected in the presence of
high ambient light. Shield the sensor area if necessary.
⚫
The following reasons will cause interference.
◼
Improper placement or alignment.
◼
Placement of a sensor on an extremity with a high pressure cuff.
◼
Extremely low perfusion.
◼
The user has hypotension severe vasoconstriction severe anemia or
hypothermia.
◼
Excessive motion.
◼
Fingernail polish or false fingernails may cause inaccurate SpO2
readings.
1.3 Warnings
WARNING:
EXPLOSION HAZARD
— Do not use the oximeter in a
flammable atmosphere where concentrations of flammable anesthetics or
other materials may occur.
WARNING:
Do not throw batteries in fire as this may causes them to
explode.
WARNING:
Do not use the pulse oximeter in an MRI or CT environment.
WARNING:
This oximeter is not a Apnea monitor, should not be used for
arrhythmia analysis.
CAUTION:
Keep the operating environment free of dust, vibrations,
corrosive, or flammable materials, and extremes of temperature and
humidity.
CAUTION:
Do not operate the unit if it is damp or wet because of
condensation or spills. Avoid using the equipment immediately after moving
it from a cold environment to a warm, humid location.
WARNING:
Do not attempt to recharge normal dry-cell batteries, they may
leak. And may cause a fire or even explode.
CAUTION:
Never use sharp or pointed objects to operate the front-panel
switches.
CAUTION:
The battery must be taken out from the battery compartment if
the device will not be used for a long time.
CAUTION:
The device shall only be used if the battery cover is closed.
CAUTION:
The battery must be proper disposed according to local
regulation after their use.

Section 2 Introduction
2.1 Display Parameter and Brief Device Description
(Functional oxygen saturation), is the amout of oxyhemoglobin expressed
as a percentage of the Functioning Hemoglobin. Functioning Hemoglobin is
capable of carrying oxygen and includes oxygenated hemoglobin (HbO2)
and deoxygenated hemoglobin (Hb).
PR
(Pulse Rate), measured in beats per minute(bpm), is the frequency of
heart beats.
PI
(Perfusion Index) is the ratio of the pulsatile blood flow to the
non-pulsatile static blood in peripheral perfusion. Perfusion index is an
indication of the pulse strength at the sensor site.
Plethysmogram
The amount of light absorbed by the varying quantities
of arterial blood changes with the pulse beats, the waveform is named
Plethysmogram , This waveform and its variation is used for assigning signal
integrity, physiological and artifactual changes such as perfusion changes,
dysrhythmia, motion artifact, and electrical interference.
The Pulse Oximeter, based on all digital technology, is intended for
noninvasive spot-check measurement of functional oxygen saturation of
arterial hemoglobin (SpO2). Advanced DSP algorithm can reduce the
influence of motion artifact and improve measurement accuracy of low
perfusion.
Section 3 Installation, Setup, and Operation
3.1 Description of the Front and Back Panel (as Figure 3.1.1 and
Table 3.1.1)
Table 3.1.1 Part Definition and Description
Figure 3.1.1 Parts of front
& back panel
3.2 Install battery
Installing two AAA batteries into battery cassette in
correct polarities and cover it(as Figure 3.2.1).
3.3 Turn the Pulse Oximeter on
Put one of fingers into rubber hole of the
oximeter (it is best to put the finger thoroughly)
with nail surface upward(as Figure 3.3.1 ), then
releasing the clamp.
Press the button, oximeter will go into the
working state.

Note: when battery power is at lowest level, the battery capacity indicates
symbol of “
”in OLED, remind users of replacement of battery.
3.5 Operate the Menu
There are two ways to operate the button according to the pressing time:
long-press is longer than
and short-press is shorter than
Short-press is used to select a item by moving a

to the line of this item,
long-press is used to change the item
’s value, status, open a new page or
make it take effect.
From the main screen, long-press on the button will make the oximeter
display Settings Pages as shown in Figure 3.5.1 or Figure 3.5.2. Selecting
“Page 1/2” or “Page 2/2” and long press will make this two pages display
alternately.
