General Description
Thank you for purchasing the OX100 Fingertip Pulse Oximeter. This
Oximeter can be used to measure your blood oxygen saturation (in
% SpO
2
) and pulse rate in hospital or homecare.
This Fingertip Pulse Oximeter features 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 precision and repeatability.
Package contents
1. OX100 Fingertip Pulse Oximeter
2. Quick operation guide
3. One AAA battery
Precaution for use
1. Read the manual carefully before use.
2. Pulse Oximeters are sensitive to motion artifacts. Keep hands
still while taking a reading.
3. Pulse Oximeters require sufficient blood flow to obtain proper
readings. Poor blood circulation can result in inaccurate readings. If
your hands are cold or you have poor circulation, warm your hands
by rubbing them together or use another method before attempting
to obtain a reading. A tourniquet, blood pressure cuff or other blood
flow hindrances may also result in inaccurate readings.
4. Fingernail polish or acrylic nails obstruct the light transmission
and may also result in inaccurate readings.
5. Your finger must be clean for proper reading.
6. The Pulse Oximeter must be clean for a proper reading.
7. If a reading is different to obtain, switch to another finger or to the
other hand.
8. The Pulse Oximeter will not alert you if your readings are out of
normal range.
9. Explosion hazard: Do not use the Pulse Oximeter in an explosive
atmosphere.
10. The Pulse Oximeter has no SpO2 alarms; it is not for continuous
monitoring, as indicated by the symbol.
11. In order to ensure correct sensor alignment and skin integrity,
the maximum application time at a single site for our device should
be less than half an hour.
12. Operation of the Pulse Oximeter may be affected by the use of
an electrosurgical unit (ESU).
13. Do not use the Pulse Oximeter in an MRI or CT environment.
14. 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.
15. Do not sterilize the device using autoclaving, ethylene oxide
sterilizing, or immersing the device in liquid. The device is not
intended for sterilization.
16. Follow local ordinances and recycling instructions regarding
disposal or recycling of the device and device components,
including batteries.
17. 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.
18. Portable and mobile RF communications equipment can affect
medical electrical equipment.
19. This equipment is not intended for use during patient transport
outside the healthcare facility.
20. This equipment should not be used adjacent to or stacked with
other equipment.
21. It may be unsafe to:
—use accessories, detachable parts and materials not described in
the instructions for use
—interconnect this equipment with other equipment not described in
the instructions for use
—disassemble, repair or modify the equipment.
22. These materials that contact with the patient’s skin contain
medical silicone and ABS plastic enclosure are all pass the ISO10993-
5 Tests for invitro cytotoxicity and ISO10993-10 Tests for irritation and
delayed-type hypersensitivity.
Inaccurate measurements may be caused by
1. Significant levels of dysfunctional hemoglobin (such as carbonyl -
hemoglobin or methemoglobin).
2. Intravascular dyes such as indocyanine green or methylene blue.
3. High ambient light. Shield the sensor area if necessary.
4. Excessive patient movement.
5. High-frequency electrosurgical interference and defibrillators.
6. Venous pulsations.
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 polish or false fingernails.
11. Weak pulse quality (low perfusion).
12. Low hemoglobin.

Battery Installation
1. Install one AAA battery into the battery compartment. Match the
plus (+) and minus (-) signs in the compartment. If the polarities are
not matched, damaged may be caused to the oximter.
2. Open the battery door as show in the picture.
Note:
The battery indicator symbol on front panel display will light when the
battery voltage is too low for normal operation of the Pulse Oximeter.
Replace the batteries when indicator symbol lights.
Warnings!
Keep the oximeter away from young children. Small items such as the
battery door, battery are choking hazards.
Using the Oximeter
1. Place one of your fingers into the rubber opening of the Pulse
Oximeter.
2. Press the switch button one time on front panel to turn the pulse
oximeter on. The Bluetooth will turn on simultaneously.
3. Keep your hands still for the reading. Do not shake your finger
during the test. It is recommended that you do not move your body
while taking a reading.
4. Read the data from the display screen.
5. When no signal or low signal is detected, the Pulse Oximeter will
power off automatically in 8 seconds.
Brief description of displaying screen
Power low indication
The height of the Pulse Bar graph indicates the intensity of the pulse
and signal strength. The bar should be greater than 30% for a proper
reading.
Sync
1. Tap the settings icon on the bottom of the screen. Choose “link or
change the device”
2. Choose “iChoice OX100” and then turn on your unit.
3. This will sync your device.
The measurements will automatically transmit to your iOS device. You
can view and analyze your progress with charts and graphs. Compare
and share goals and progress with friends and family.
Maintenance
1. Clean the Pulse Oximeter and sensor with a soft cloth dampened
with isopropyl alcohol. Do not pour or spray any liquids onto the Pulse
Oximeter. Do not allow any liquid to enter any openings in the device.
Allow the Pulse Oximeter to dry thoroughly before reusing. (The rubber
inside of the Pulse Oximeter is composed of medical grade rubber. It is
non toxic and is not harmful to the skin.)
2. The Pulse Oximeter requires no routine calibration or maintenance
other than replacement of the batteries.
Service life of device
The use life of the device is five years when it is used for 15
measurements every day and 10 minutes per one measurement.
