Fingertip Pulse Oximeter
Orygen Saturation is a percentage of Oxyhemoglobin (HbO2) capacity, compounded
with orygen, by all combinative hemoglobin (Hb) capacity in blood In other words, it is
consistency of Oxyhemoglobin in blood. lt is a very important parameter tor the
Respiratory Circulation System Many respiratory diseases can result in orygen
saturation being lowered in human blood. Additionally, the following factors can reduce
orygen saturation: Automatic regulation of organ dysfunction caused by Anesthesia,
Intensive Postoperative Trauma, injuries caused by some medical examinations. That
situation mlght result in light-headedness, asthenia, and vomiiing. Theretore, it is very
important to know the oxygen saturation of a patient so that doctors can find oroblems in
a timely manner.
The fingertip pulse Oximeter features small size, low power consumption, convenient
operation and portability. lt is only necessary for a patient lo put one of his fingers into
the fingertip photoelectric sensor for diagnosis, and a display screen will show orygen
saturation. lt has been proven in clinical eperiments that it also features high precision
and repeatability.
Do not use the pulse oximeter in an MRI or CT environment or in the Dresence of
a FLAMMABLE ANAESTHETIC MIXTURE
Do not use the pulse oximeter in situations where alarms are required The device
has no alarms.
Explosion hazard: Do not use the pulse oximeter in an e4,losive atmosphere.
The pulse oximeter is intended only as an adjunct in patient assessment. lt must
be used in conjunction with other methods of assessing clinical signs and
symproms
Check the pulse oximeter sensor application site frequentty to determine the
positioning of the sensor and circulation and skin sensitivity of the patient
Do not stretch the adhesive tape while applying the pulse oximeter sensor. This
may cause inaccurate readings or skin blisters
Before use, caretully read the manual.
The pulse oximeler has no SpO2 alarms; it is not for continuous monitoring.
Prolonged use or the patient'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
Inaccurate measurements may be caused by autoclaving, ethylene oxide
sterilizing, or immersing the sensors in liquid may cause inaccurate readings.
Signihcant levels of dysfunctional hemoglobins (such as carbonry- hemoglobin or
methemoglobin) may affect the readings
Intravascular dyes such as lndocyanine green or methylene blue
SpO2 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.
Excessive patient movement may affect the readings
Venous pulsations may affeet the readings.
HighJrequency electrosurgical interference may affect the readings
Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter,

Operation of the product is simple and convenient
The product is small in volume, light in weight and convenient in carrying.
Power consumption of the product is low and the two originally-equipped two
AAA batteries can be operated continuously for gO hours.
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.
The product will automatically be powered otf when no signal is in the product for
longer than 8 seconds.

Place clamp over finger nail per diagram.
Insert one finger into rubber hole ol the Oximeter fully
Press the switch button once on front panel.
Finger and body should not tremble during measuring
Read correspondent data from display screen.
Six display modes
Principle ot the Oximeter is as follows: A mathematical formula is established making
use of Lambert Beer Law according to Spectrum Absorption Characteristics ot
Reductive hemoglobin(RHb) and Oryhemoglobin (HbO2) in glow and near-infrared
zones Operation principle of the instrument: Photoelectric Oryhemoglobin Inspection
Technology is adopted in accordance with Capacity Pulse Scanning and Recording
Technology, so that two beams of different wavelength of lights (66Onm glow and 94Onm
near infrared light) can be focused onto a human nail tip through a clamping finger-type
sensot A measured signal obtained by a photosensitive element, will be shown on the
Oximeter's display through process in electronic circuits and microprcessor snown on
the Oximeter's display through electronic circuits ":J a microprocessor.

Alarm range:
SpOz:<90
Pulse rate: <60 or >.100
Visual alarm: The measuring value will be flashing when it is through over the
alarm limitation.
Audio alarm: The audible alarms can be heard if there is no silence The buzzel
will beep shortly for two times when the value exceeds the alarm limitation.
Alarm silence:
When the audio alarm occurs, press the button and then the Oximeter will enter
into the'alarm silence mode" for gO seconds, and then there is only the visual
alarm. This silence operating has only effect on the alarm sound not on the oulse
rate sound.
In the sllence mode, press the button, and then the display mode will be
changed.
It will exit the silence mode automatically when a new alarm o@urs or lhe value
is in the normal range again.
NOTE:
a Please use the to clean the rubber touching the finger inside of
Oximeter, and ensor using alcohol before and after operation.
(The rubber ins ter is medical rubber, which has no toxin, and no
harm to the skin)
a The internal spring provides the correct pressurer additional pressure may cause
inaccurate readings.
