Instructions to User
Read these instructions carefully before using this equipment. These
instructions describe the operating procedures to be followed strictly.
Failure to follow these instructions can cause measuring abnormality,
equipment damage and personal injury. The manufacturer is NOT re-
sponsible for the safety, reliability and performance issues and any mon-
itoring abnormality, personal injury and equipment damage due to user’s
negligence of the operation instructions. The manufacturer’s warranty
service does not cover such faults.
- The contents contained in this manual are subject to change without
notice.
- The uncomfortable or painful feeling may appear if using the device
ceaselessly, especially for the microcirculation barrier patients. It is
recommended that the sensor should not be applied to the same
nger for over 2 hours- If any abnormal condition is found, please
change the position of Pulse Oximeter.
- For the individual patients, there should be a more prudent inspecting
in the placing process. The device can not be clipped on the edema
and tender tissue.
- The light (the infrared is invisible) emitted from the device is harmful to
the eyes, so the user and the maintenance man, can not stare at the
light.- The Pulse Oximeter is not a treatment device.
- Testee can not use enamel or other makeup on the nge.
- Testee’s ngernail can not be too long- Please peruse the relative con-
tent about the clinical restrictions and caution.
1. SAFETY
1.1 Instructions for Safe Operations
- Check the main unit and all accessories periodically to make sure
that there is no visible damage that may affectpatient’s safety and
monitoring performance with regard to sensors and clips. It is recom-
mended that the device should be inspected minimally before each
use. When there is obvious damage, stop using the oximeter.
- Necessary maintenance must be performed by qualid service tech-
nicians ONLY. Users are not permitted to maintain it by themselves.
ENGLISH

21
- The oximeter cannot be used together with the devices and accesso-
ries not specied in Use’s Manual.
- Special attention should be paid while the Pulse Oximeter is used
constantly when the ambient temperature over 37°C, burning hurt
may occur because of over-heating of the sensor at this situation.
1.2 Attentions
- Keep the oximeter away from dust, vibration, corrosive sub-
stances, explosive materials, high temperature and moisture.
– The device should be kept out of the reach of children.
- If the oximeter gets wet, please stop using it and do not resume oper-
ation until it is dry and checked for correct operation. When it is car-
ried from cold environment to warm and humid environment, please
do not use it immediately. Allow at least 15 minutes for Pulse Oximeter
to reach ambient temperature.
- DO NOT press the keys on front panel with sharp materials or sharp
points.
- High temperature or high pressure steam disinfection to the oximeter
is not permitted. Refer to User’s Manual for instructions of cleaning
and disinfection.
- The nger should be put in properly and correctly.
- Do not shake the nger. Keep at ease during measurement.
- Do not put wet nger directly into sensor.
- Do not let anything block the emitting light from the device.
- Ensure that there is artery vessel within measuring site where the light
transmits through.
- Vigorous exercise and the interference from the electrosurgical device
may affect the measuring accuracy.
- If the rst reading appears with poor waveform (irregular or not
smooth), then the reading is unlikely true, the more stable value is ex-
pected by waiting for a while, or a restart is needed when necessary.
2. OVERVIEW
SpO2is the saturation percentage of oxygen in the blood, so called O2
concentration in the blood; it is dened by the percentage of oxyhemo-
ENGLISH

22
globin (HbO2) in the total hemoglobin of the arterial blood. SpO2is an
important physiological parameter to reect the respiration function; it is
calculated by the following method:
SpO2= HbO2/ (HbO2+Hb)×100%
HbO2are the oxyhemoglobins (oxygenized hemoglobin), Hb are those
hemoglobins which release oxygen.
2.1 Features
- Large true color OLED display of SpO2, PR Pulse Bar, PI & Plethys-
mogram.
- Innovative 4 directions display.
- Automatic power on/off.
- Audible & visible over-limit indication.
- Shift parameter display between PR and PI.
2AAA alkaline batteries with low power consumption.
- Low battery voltage indication.

2.2 Major Applications and Scope
The Fingertip Oximeter is compact, convenient to use and carry and
with low power consumption. You just need to put the ngertip into the
sensor of the device, the SpO2value will appear on the screen imme-
diately.
The Fingertip Oximeter can detect SpO2and pulse rate through pa-
tient’s nger.
This device is applicable to home, hospital (including internal medicine,
surgery, anesthesia, pediatrics, emergency room etc.), oxygen bar, the
community medical center, alpine area and it also can be used before or
after sports, and the like.
This device is not appropriate to be used for continuous mon-
itoring.
2.3 Principle of Measurement
Based on Lamber-Beer law, the light absorbance of a given substance is
directly proportional with its density or concentration. When the light
with certain wavelength emits on human tissue, the measured intensity
of light after absorption, reecting and attenuation in tissue can reect
the structure character of the tissue by which the light passes. Due to
that oxygenated hemoglobin (HbO2) and deoxygenated hemoglobin
(Hb) have different absorption character in the spectrum range from red
to infrared light (600nm~1000nm wavelength), by using these character-
istics, SpO2can be determined. SpO2measured by this Pulse 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 metahemo-
globin.
Clinical application of pulse oximeters: SpO2is an important phys-
iological parameter to reect the respiration and ventilation function,
so SpO2monitoring used in treatment has become more popular. (For
example, such as monitoring patients with serious respiratory disease,
patients under anesthesia during operation and premature and neo-
natal infants) The status of SpO2can be determined in timely manner
ENGLISH

by measurement and will allow nding the hypoxemia patient earlier,
thereby preventing or reducing accidental death caused by hypoxia
effectively.
Factors affecting SpO2measuring accuracy (interference reason)
- Intravascular dyes such as indocyanine green or methylene blue.
- Exposure to excessive illumination, such as surgical lamps, bilirubin
lamps, uorescent lights, infrared heating lamps, or direct sunlight.
- Vascular dyes or external used color-up product such as nail enamel
or color skin care.
- Excessive patient movement.
- Placement of a sensor on an extremity with a blood pressure cuff,
arterial catheter, or intravascular line.
- Exposure to the chamber with High pressure oxygen.
- There is an arterial occlusion proximal to the sensor.
- Blood vessel contraction caused by peripheral vessel hyperkinesias
or body temperature decreasing.
Factors causing low SpO2Measuring value (pathology reason)
- Hypoxemia disease, functional lack of HbO2.
- Pigmentation or abnormal oxyhemoglobin level.
- Abnormal oxyhemoglobin variation.
- Methemoglobin disease.
- Sulfhemoglobinemia or arterial occlusion exists near sensor.
- Obvious venous pulsations.
- Peripheral arterial pulsation becomes weak.
- Peripheral blood supply is not enough.
2.4 Caution
A. The nger should be placed properly (see the gure 3 of this manual),
or else it may cause inaccurate measurement.
B. The SpO2sensor and photoelectric receiving tube should be ar-
ranged in a way with the subject’s arteriole in a position there be-
tween.
C. The SpO2sensor should not be used at a location or limb tied with
ENGLISH

25
arterial canal or blood pressure cuff or receiving intravenous injec-
tion.
D. Do not x the SpO2sensor with adhesive or else it may result in
venous pulsation and inaccurate measure of SpO2.
E. Make sure the optical path is free from any optical obstacles like
rubberized fabric.
F. Excessive ambient light may affect the measuring result. It includes
uorescent lamp, dual ruby light, infrared heater, direct sunlight and
etc.
G. Strenuous action of the subject or extreme electrosurgical interfer-
ence may also affect the accuracy.
3. BATTERY INSTALLATION
1. Press the lock button of the battery cover, meanwhile, pull the cover
back and take it out.
