Pulse Oximeter
USER MANUAL
Ver2.0CF3
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 low power consumption, convenient operation and portability. Place one fingertip into the
photoelectric sensor for diagnosis and the pulse rate and oxygen saturation will appear on the display. It has been proven in clinical
experiments that it also features high precisionand 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.

Precautions For Use
1 Before use, carefully read the manual.
2 Operationof the fingertip pulse oximeter may be affected by the use of an electrosurgical unit (ESU).
3 The fingertip pulse oximeter must be able to measure the pulse properly to obtain an accurate SpO2 measurement. Verify
that nothing is hindering the pulse measurement before relying on the SpO2 measurement.
4 Do not use the fingertip pulse oximeter in an MRI or CT environment.
5 Do not use the fingertip pulse oximeter in situations where alarms are required. The device has no alarms. It is not for
continuous monitoring.
6 Do not use the fingertip pulse oximeter in an explosive atmosphere.
7 The fingertip pulse oximeter is intended only as an adjunct in patient assessment. It must be used in conjunctionwith other
methods of assessing clinical signs and symptoms.
8 Check the pulse oximeter sensor application site every 4 hours to determine the positioning of the sensor and circulation
and skin sensitivity of the patient.
9 Do not sterilize the device using autoclaving, ethylene oxide sterilizing, or immersing the device in liquid. The device is not
intended for sterilization.
10 Follow local ordinances and recycling instructions regarding disposal or recycling of the device and device components,
including batteries.
11 This equipment complies with IEC 60601-1-2:2007 for electromagnetic compatibility for medical electrical equipment and/or
systems. However, because of the proliferation of radio-frequency transmitting equipment and other sources of electrical
noise in healthcare and other environments, it is possible that high levels of such interference due to close proximity or
strength of a source might disrupt the performance of this device.
12 Portable and mobile RF communicationsequipment can affect medical electrical equipment.
Rx only: “Caution: Federal law restricts this device to sale by or on the order of a physician.”
Inaccurate measurements may be caused by
1 Significant levels of dysfunctional hemoglobin(such as carbonyl - hemoglobinor methemoglobin);

7 Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or intravascular line;
8 The patient has hypotension, severe vasoconstriction,severe anemia, or hypothermia;
9 The patient is in cardiac arrest or is in shock;
10 Fingernail polishor false fingernails;
11 Weak pulse quality (low perfusion);
12 Low hemoglobin;
Product Properties

humidity .
5. Keep in a dry place. Extreme moisture may affect oximeter lifetime and may cause damage.
6. Dispose of battery properly; follow any applicablelocal battery disposal laws.
Cleaning the fingertip pulse oximeter
Please use medical alcohol to clean the silicone touching the finger inside of oximeter with a soft cloth dampened with 70%
isopropyl alcohol.Also clean the being tested finger using alcohol before and after each test.
Do not pour or spray liquids ontothe oximeter, and do not allow any liquid to enter any openings in the device. Allow the oximeter to
dry thoroughly before reuse.
A functional tester cannot be used to assess the accuracy of a pulse oximeter monitor or sensor. Clinical testing is used to establish
the SpO2 accuracy. The measured arterial hemoglobin saturation value (SpO2) of the sensors is compared to arterial hemoglobin
oxygen(SaO2) value, determinedfrom blood samples with a laboratory CO-oximeter. The accuracy of the sensors in comparisonto
the CO-oximeter samples measured over the SpO2 range of 70 –100%. Accuracy data is calculated using the
root-mean-squared(Arms value)for all subjects, per ISO 9919:2005,Medical Electrical
Equipment – Particular requirements for the
basic safety and essential performance of pulse oximeter equipment for medical use.
The use life of the device is five years when it is used for 15 measurements every day and 10 minutes per one
measurement. Stop using and contact local service center if one of the following cases occurs:
An error in the Possible Problems and solutions is displayed on screen.
The oximeter cannot be powered on in any case and not the reasons of battery.
There is a crack on the oximeter or damage on the display resulting readings cannot be identified; the spring is invalid; or the
key is unresponsive or unavailable.
