HOLFENRY B0B429Q7CF Pulse Oximeter for Kids User Manual

Operator’s Manual
Fingertip Pulse Oximeter

General Description

The measurement of oxygen saturation of arterial blood (also known as pulse oxygen saturation, usually shortened as SpO2) adopts the principles of light spectra and volume tracing. The LED emits lights with two specific wavelengths,  which are selectively absorbed by oxygenated hemoglobin and deoxyhemoglobin. The optical receptor measures the changes in the light intensity after the light passes the capillary network and estimates the ratio of oxygenated hemoglobin  and the total hemoglobin.

oxyhemoglobin + deoxyhemoglobin

Precautions for use

• Please pay attention to the positive and negative signs when installing the battery.
• Do not measure under strong light, strong light will interfere with blood oxygen measurement results.
• Children over 2 years old can measure their fingers. When measuring, use your own hands to help the child to fix the measurement and avoid moving.
• Children under the age of 2 can measure their big toe and hold it on the big toe with their hands to keep it steady and not wobbling.

• Explosion hazard. Do not use the oximeter in the presence of flammable anesthetics mixture with air, oxygen, or hydrogen.
• When the oximeter is in use, there should not be any great power appliances as high voltage cables, X-ray machine, ultrasound equipment and electrizer in use nearby.
• Keep the oximeter away from dust, vibration, corrosive substances, explosive materials, high temperature and moisture.
• This oximeter for sports or aviation use only.
• The oximeter should be handled with care so as to avoid shocks and falls.
• When the oximeter is in use, it must be ensured the batteries have sufficient capacity; otherwise there might be such phenomena as starting-up abnormalities or inaccurate measurement data, etc.
• Please do not use such pointed objects as pen point or nails for pressing operation, otherwise it might cause permanent damage to the surface of the keyboard.

Operation Instructions

1. Install two AAA batteries into battery cassette before closing its cover.
2. Nip the oximeter, then insert one of fingers into the rubber hole of the oximeter before releasing the oximeter, and your nail surface must be upward.
3. Press the function button once on front panel.
4. Your finger and body do not tremble during measuring.
5. Press the function button to switch the display of PI and heart rate.

Note:

• The measurement time is affected by the skin color of the subject. When the oximeter is used by people with dark skin, a longer measurement time is required.
• Since the oximeter measures continuously, the displayed value is updated in real time. Please use it with confidence.
  Why does the reading always change?
  The pulse oximeter measures data in real time. Since the body changes dynamically, the results also change over time. Please use it with confidence.
  ① Pulse intensity histogram
  ② SpO2 reading
  ③ Pulse rate reading or perfusion index reading
  ④ Perfusion index (Toggle display of PI and PR at the touch of a button)

Battery Installations

1. Press the battery cover of oximeter and push down.
2. Install the two AAA batteries into battery cabin in correct polarities. (As shown on the right)
3. Close the battery cover.

Notes:

• Pay attention to the correct polarities terminals of the battery, which are marked with plus and minus signs. Do not install the battery in the direction of the spring.
• Please remove the battery if the oximeter will not be used for long time.

Maintenance

1. Use a soft cloth dampened with either a commercial, nonabrasive cleaner, or a solution of 70% alcohol in water, lightly wipe the surfaces of the oximeter.
2. The most commonly used cleaning agent and non-corrosive detergents an be used for cleaning the oximeter, but please be careful that many types of detergents must be diluted before use; Please use them according to the directions of the manufacturers of the detergents.
3. Avoid using alcohol-based, amido or acetone-based detergents
4. The casing of the oximeter should be kept from the contamination of filth and dirt, and it can be wiped with non-velvet soft cloth. When cleaning, do not spill the liquid onto the instrument. Ensure no liquid is allowed to enter the  inside of the oximeter.
5. It is forbidden to use such grinding materials as wire brush or metal polishing agent, because these materials may cause damage to the panels of the oximeter.
6. Please do not soak the oximeter in liquid.
7. Under normal circumstances, it is unnecessary for the oximeter to have special maintenance, and cautions must be exercised on the following points during the use of the oximeter:
   Please use the oximeter in the environment according to the requirements of the performance criteria.
   Avoid contacts with organic solutions, dusts or corrosive gases.

ones.| The batteries may be missing, discharged, or oriented incorrectly. Replaced them with new
Battery installation error| Please check whether the positive and negative directions of the battery are consistent with the positive and negative directions of the battery compartment.
The Pulse search time is too long| Perfusion may be too low| Check the person.
Change the measuring site. Try another
person movement| Interference due to
person activity may be preventing the oximeter from tracking the pulse. Keep the person still, if possible.
Electromagnetic interference may be preventing the oximeter from tracking the pulse.| Remove the source of interference.
There may be interference due to ambient light, or the oximeter may be on an extremity with a blood pressure cuff, arterial catheter, or intravascular line.| Reposition oximeter, as necessary.
Display is dark-or-bright| Battery capacities are low.| Replace the batteries.
