Gen era l D esc r iption
Oxygen Saturation is a percentage of Oxyhemoglobin (Hb02) 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 patient 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 patient 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 .
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 (Hb02) 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 tight) 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.

I
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 patient 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 patient.
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 Sp0 2 alarms; it
is not for Continuous monitoring.
9 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.
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 affect the readings.
12
Intravascular dyes such as indocyanine green or methylene blue
13
Sp02 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 patient movement may cause inaccurate readings.
15 High-frequency electrosurgical interference may cause inaccurate readings.
16 Venous pulsations may cause inaccurate readings.
17 Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or
intravascular line.
18
The patient has hypotension, severe vasoconstriction, severe anemia, or
hypothermia.
19 The patient is in cardiac arrest or is in shock.
20
Fingernail polish or false fingernails may cause inaccurate Sp0
2 readings.
Follow local ordinances and recycling instructions regarding disposal or
recycling of the device and device components, including batteries.

Fingertip PULSE OXIMETER is a portable non-invasive, spot-check, oxygen saturation
of arterial hemoglobin
(SPO2)
and pulse rate of adult and pediatric patient at home, and
hospital (including clinical use in internist/surgery, Anesthesia, intensive care etc(. It is
not for continuously monitoring.
The PULSE OXIMETER requires no routine calibration or maintenance other than
replacement of batteries,
Operation Instructions
1 
Install two AAA batteries into battery cassette before closing its cover.
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 for one time on front panel.
5  Finger and body should not tremble during measuring
6  Read corresponding data on the display screen.
Note: Please use medical alcohol to clean the rubber, inside the Oximeter, that touches
the finger. Also, clean the test finger with alcohol before and after each test. (The rubber
inside of the Oximeter is medical rubber, which has no toxins, and is not harmful to the
skin). 
