When placing sensor in right place, please abide by work instructions
strictly, for example do not extend tape or fix it too tightly.
When beginning to measure associated body features please follow the
doctor’s counseling.
When link this equipment to other peripherals, make sure you are
sophisticated operator to handle this device. Any peripherals should be in
the light of protocol of IEC 950 and IEC 601-1-1. Any input/output device
should be following the protocol of IEC 601-1-1.
Please strictly follow the sensor application instructions, considering the
sensor is a sensitive device.
The malfunction of sensor may cause inaccurate data which serve as a
foundation to treat patients, so please make sure to pay more attention to
the sensor and inspect it frequently.
The worn-out data cables may cause inaccurate data and be used as a
reference to treat patient, so please pay attention to data cable and check it
frequently.
The disposable peripheral should not be repeatedly used.
Precautions
Rinsing the sensors with ethylene oxide solution may have adverse
influence on the machine, Apart from this, the sensor should not be
autoclaved or submerged.
This device is intended for use by persons trained in professional health
care. The operator must be thoroughly familiar with the information in this
manual before using the device.
Unplug the sensor from the monitor before cleaning or disinfecting to avoid
the damage to the device and user.
Alarm must be set up according to different situation of individual patient.
Make sure that chime sound can be activated when alarm function begin to
work.
Notices
Application of this device may influence the measuring accuracy in the
background of electromagnetic areas such as electro-surgery environment.

readings. Pay more attention to the application when applying this device
under the situation of computed tomography (CT) environment.
SpO2measurements may be adversely affected in the presence of high
ambient light. Shield the sensor area (with a surgical towel, for example) if
necessary.
Dyes introduced into the bloodstream, such as methylene blue,
indocyanine green, indigo carmine, and fluorescein, may adversely affect
the accuracy of the SpO2reading.
Any condition that restricts blood flow, such as use of a blood pressure cuff
or extremes in systemic vascular resistance, may cause a failure to
determine accurate pulse rate and SpO2readings.
Remove fingernail polish or artificial fingernails before applying SpO2
sensors. Fingernail polish or artificial fingernails may lead to inaccurate
SpO2readings.
SpO2average is the number of pulse beats over which the SpO2value is
averaged; pulse average is the number of seconds over which the pulse
value is averaged.
Hazards arising from software errors have been minimized. Hazard
analysis conforms to meet ISO14971: 2000 and EN60601-1-4: 1996.
Significant levels of dysfunctional hemoglobins, such as
carboxy-hemoglobin or methemoglobin, will affect of the accuracy of the
SpO2measurement.
Optical cross-talk can occur when two or more sensors are located in
adjoining area. It can be eliminated by covering each site with opaque
material. Optical cross-talk may adversely affect the accuracy of the SpO2
readings.
Change new batteries in time, when the power low indicator appears. As,
the readings will influenced when the power is low.
Obstructions or dirt on the sensor’s red light or detector may cause a
sensor failure. Make sure there are no obstructions and the sensor is clean.
For routine equipment maintenance, please refer to the service procedures
at the associated section as indicated in the manual.
As to the other concerns for attention, please carefully look through the
specific chapter in this instruction.

1.3 Intended Use
The purpose and function of the handheld pulse oximeter is to indicate
measure and display the functional oxygen saturation of arterial hemoglobin
(SpO2) and pulse rate for adults and pediatric patients in hospital, ambulatory,
home, and EMS (emergency medical service) environments. The pulse
oximeter is intended for spot-checking these levels and not indicated for
continuous monitoring. It can assist the clinician diagnostically by quickly
displaying the patient’s SpO2% and pulse rate and can additionally store 72
hours of data.
1.4 Electromagnetic Interference
This oximeter is designed and tested in compliance with the EMC standard,
complying with the international standard for the EMC of the electronic
medical device - IEC 60601-1-2. However, because of the proliferation of radio
frequency transmitting equipment and other sources of electrical noise in the
health-care and home environments (e.g. cellular phones, mobile two-way
radios, electrical appliances) it is possible that high levels of such interference
due to close proximity or strength of a source, may result in disruption of
performance of this device.
This apparatus complies with the IEC 60601-1-2 international standard. The
requirements of this international standard are: CISPR11, GROP1, and
CLASS B
1.5 Equipment Classification
CHAPTER 2 General Descriptions

Fig.16 Placement of the sensor
Select the suitable sensor in terms of type and dimension.
Clip the sensor to the rational position of the patient finger.
Plug sensor into SpO2port on top panel of pulse oximeter.
Note：If the finger is not in the sensor, “Finger Out”will be shown on the
bottom of the screen.
Warnings!
The measurement would not be performed if the following instances
come across in operation:
Shock
Low temperature of hand
Have taken vascular activity medicine
Anemia
carboxyhemoglobin
methemoglobin
methylene blue
Indigo carmine

V1.0I2 PULSE OXIMETER OPERATOR＇SMANUAL

Use only SpO2sensors provided by the manufacturer for SpO2
measurements. Other SpO2sensors may cause improper performance.
Do not use a SpO2sensor with exposed optical components.
Excessive patient movement may cause inaccurate measurements.
Tissue damage can be caused by incorrect application or use of sensor, for
example by wrapping the sensor too tightly. Inspect the sensor site to
ensure skin integrity and correct positioning and adhesion of the sensor.
More frequently inspection should be taken depend on different patients if
necessary.
Set the upper limit of SpO2alarm to 100% means cut off the upper alarm.
High density of oxygen will cause adverse affection to the neonate .So the
upper limit of SpO2alarm must be selected prudently according to the
acknowledged clinical practice.
Inaccurate measurements may be caused by:
Incorrect sensor application or use
Significant levels of dysfunctional hemoglobins (such as c
arboxyhemoglobin or methemoglobin)
Intravascular dyes such as indocyanine green or methylene blue
Exposure to excessive illumination, such as surgical lamps (especially
ones with a xenon light source), bilirubin lamps, fluorescent lights,
infrared heating lamps, or direct sunlight
High-frequency electro surgical interference and defibrillators
Venous pulsations
Placement of a sensor on an extremity with a blood pressure cuff,
arterial catheter, or intravascular line
The patient has hypotension, severe vasoconstriction, severe anemia,
or hypothermia
There is arterial occlusion proximal to the sensor
The patient is in cardiac arrest or is in shock
Loss of pulse signal can occur in any of the following situations:
The sensor is too tight
There is excessive illumination from light sources such as a
surgical lamp, a bilirubin lamp, or sunlight
A blood pressure cuff is inflated on the same extremity as the one to
which an SpO2sensor is attached
Note：Pulse sensor should obviate the light source, e.g. radial lamp or
infrared lamp.
