Fingertip Pulse Oximeter
General Description
Oxygen Saturation is a percentage of Oxyhemoglobin (HbO2) 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.
Measurement Principle
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 (HbO2) 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 light) 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.

Product Operation Scope
Fingertip Pulse Oximeter is a portable non-invasive, spot-check, oxygen saturation of
arterial hemoglobin (SpO2) and pulse rate of adult and pediatric patients at home, and
hospital (including clinical use in internal medicine/surgery, anesthesia, intensive care
and etc). The device is not intended for continuously monitoring.
The PULE OXIMETER requires no routine calibration or maintenance other than
replacement of batteries.

Precautions for use
1 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 SpO2alarms; it is not for continuous monitoring, as
indicated by the symbol.
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 may cause inaccurate readings.
11 Significant levels of dysfunctional hemoglobins(such as carbonxy-hemoglobin
or methemoglobin).
12 Intravascular dyes such as indocyanine green or methylene blue
13 SpO2measurements 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 accurate readings.
15 Venous pulsations may cause accurate readings.
16 Placement of a sensor on an extremity with a blood pressure cuff, arterial
catheter, or intravascular line may cause accurate readings.
17 The patient has hypotension, severe vasoconstriction, severe anemia, or
hypothermia.
18 The patient is in cardiac arrest or in shock.
19 Fingernail polish or false fingernails may cause inaccurate SpO2readings.
Follow local ordinances and recycling instructions regarding disposal or
recycling of the device and device components, including batteries.

oximeter used to measure the arterial haemoglobin oxygen saturation levels and
these levels are to be compared to the levels determined from arterial blood
sampling with a CO-oximeter.
3. Index 2 that made by Bioteck company is a function tester. Set Tech to 1, R curve
to 2, and then users can use this particular calibration curve to measure the
oximeter.
