Warnings
Check the device to make sure that there is no
visible damage that may affect user’s safety or
measurement performance with regard to sensors
and clips. It is recommended that the device
should be inspected minimally once a week.
When there is obvious damage, stop using the
device.
Special attention should be paid while the
oximeter is used continuously under the ambient
temperature exceeds 37°, burn ing hu rt may occ ur
because of over-heating on the s ensor.
An uncomfortable or painful feeling may appear
if using the oximeter continuously on the same
place for a long time, especially for poor
microcirculation patients.
It is recommended that the oximeter should not
be applied to the same location for longer than 2
hours. If any abnormal condition is found, please
change the position of oximeter.
Avoid pla cin g th e d evic e on th e s ame limb which
is wrapped with a cuff for blood pressure
measurement or during venous infusion.

DO NOT clip this device on edema or tender
tissue.
The light (the infrared light is invisible) emitted
from the device is harmful to the eyes, so service
technician or test ee s hould not stare a t the light.
The oximeter is not a treatment device.
When disposing of the monitor and its
accessories, the local law should be followed.
Instructions for Operation
The finger should be put in properly and correctly.
Do not shake the finger. Keep at ease during
measurement.
Do not put wet finger directly into sensor.
Avoid placi ng the d evice on th e sa me limb whi ch
is wrapped with a cuff for blood pressure
measurement or during venous infusion.
Do not let anythin g block the emittin g light from
device.
Vigorous exercise and electrosurgical device
interference may affect the measuring accuracy.
The orientation-sensor works on the basis of the
gravit y. A small movab le metal ball is bu ilt in the
orientation-sensor for det ecting the orienta tion of

the oximeter. When you want to change the
oximeter’s display direction, if you move the
oximeter too slowly, the movable metal ball will
also move slowly because of not enough
acceleration. Consequently the response of
orientation detection would be delayed. Please
move the oxi meter with a bit of force i f you want
to change the display direction (such as
bend/extend your finger quickly), so an
acceleration is provided to the orientation-sensor
for quick sensing th e orientation change.
Using enamel or other makeup on the nail may
affect the accuracy of measurement, too long
fingernail may casue failure of measurement or
unaccuracy measurem ent result.
Keep the oximeter away from dust, vibration,
corrosive substances, explosive materials, high
temperature and moisture.
Existen ce of high intensi ve light sources, such as
fluorescence light, ruby lamb, infrared heater or
strong sunshire, etc. may cause unaccuracy of
measurement result. Please put an opaque cover
on the sensor or change the measuring site.
If the first reading appears with poor waveform
(irregular or not smooth), then the reading is

unlikely true, the more stable value is expected
by waiting for a while, or a restart is needed when
necessary.
Note: Due to the working principle of or ient ation sensor
used in oximeter, there is a small metal ball which is
movable within its compartment of the
orientation-sensor. Therefore you can hear a slight
“clatt er” sound when you wave or shake the oxim eter. It
is normal and not caused by unwanted part.

B SpO2 Common Knowledge
1. Meaning of SpO
2
SpO2 is the saturati on percent age of oxygen in th e blood,
so called O
2
concentration in the blood; it is defined by
the percentage of oxyhemoglobin (HbO
2
) in the total
hemoglobin of the arterial blood. SpO
2
is an important
physiologi c al p aram eter t o reflect the respiration function;
it is calculated by the followi ng method:
SpO
2
= HbO2/ (HbO2 +Hb)×100%
HbO
2
are the oxyhemoglobins (oxygenized
hemoglobin), Hb are those hemoglobins which release
oxygen.
2. Principle o f Me asurement
Based on Lamber-Beer law, the light absorbance of a
given subs tance is dir ect ly pr oporti on al with it s d ensit y or
concentration. When the light with certain wavelength
emits on human tissue, the measured intensity of light
after absorption, reflecting and attenuation in tissue can
reflect the structure character of the tissue by which the
light passes. Due to that oxygenated hemoglobin (HbO
2
)
Page 29
User Manual for Fingertip Oximeter
22
and deoxygenated hemoglobin (Hb) have different
absorption character in the spectrum range from red to
infrared light (600nm~1000nm wavelength), by using
these characteristics, SpO
2
can be determined. SpO2
measured by this oximeter is the functional oxygen
saturation -- a percentage of the hemoglobin that can
transport oxygen. In contrast, hemoximeters report
fractional oxygen saturation – a percentage of all
measured hemoglobin, including dysfunctional
hemoglobin, such as carboxyhemoglobin or
metahemoglobin.
Clinical application of pulse oximeters: SpO
2
is an
important physiological parameter to reflect the
respiration and ventilation function, so SpO
2
monitoring
used in t re at m en t h as b ecom e more popula r. (For ex a mp l e,
such as monitoring patients with serious respiratory
disease, patients under anesthesia during operation and
premature and neonatal infants) The st atus of SpO
2
c an be
determined in timely manner by measurement and will
allow finding the hypoxemia patient earlier, thereby
preventing or reducing accidental death caused by
hypoxia effectively.

3.Factors affecting SpO2 measuring accuracy
(interferen ce reason)
Intravascular dyes such as indocyanine green or
methylene blue
Exposure to excessive illumination, such as surgical
lamps, bilirubin lamps, fluorescent lights, infrared
heating lamps, or direct sunlight.
Vascular dyes or external used color-up product
such as nail enamel or color ski n care
Excessive patient movement
Plac ement of a sensor on an extremity with a blood
pressure cuff, arterial cathete r, or intravascular line
Exposu r e to the chamber with High pressure
oxygen
There is an arteria l occlusion proximal to the
sensor
Blood vessel contraction caused by peripheral
vessel hyperkinesias or body temperature
decreasing
Page 31
User Manual for Fingertip Oximeter

4. Factors causing low SpO2 Measuring value
(pathology reason)
Hypoxemia disease, functional lack of HbO
2
Pigmentation or abnormal ox yhemoglobin leve l
Abnormal oxyhemoglobin va riation
Methemoglobin disease
Sulfhemoglobinemia or arterial occlusion exists
near sensor
Obvious veno us pul sations
Peripheral arterial pul satio n beco m es we ak
Peripheral blood supply is not enough
