easy home EHP035 Fingertip Pulse Oximeters

General Description
The Easy@Home Fingertip Pulse Oximeter EHP035 is a handheld non-invasive device intended for spot-checking of oxygen saturation of hemoglobin (SpO2) and Pulse Rate of adults, adolescents and children in the home setting. Oxygen binds to hemoglobin in red blood cells when moving through the lungs. It is transported through­out the body as arterial blood. A pulse oximeter uses two frequencies of light (red and infrared) to determine the percentage (%) of hemoglobin in the blood that is saturated with oxygen. The percentage is called blood oxygen saturation, or SpO2. A pulse oximeter also measures and displays the pulse rate at the same time it measures the SpO2 level. Follow and read the operating procedure closely as found in these instructions. Otherwise, abnormality, equipment damage, or personal injury may occur. The manufacturer warranty does not include these safety and reliability issues noted above due to user negligence.
NOTE: This oximeter it is for sport or aviation use only and is NOT intended for medical use.

Measurement Principle
The principle of the oximeter is as follows:

• The pulse oximeter works by applying a sensor to either pointer finger.
• The sensor contains a dual light source and photodetector.
• The one wavelength of the light source is 660nm, which is red light; the other is 905nm, which is infrared-red light. Skin, bone, tissue, and venous vessels normally absorb a constant amount of light over time.
• The photodetector in the finger sensor collects and converts the light into an electronic signal which is proportional to the light intensity.
• Systolic blood pressure is the first number measuring the pressure in your blood vessels when your heart beats; the second number is diastolic blood pressure measuring the pressure in your blood vessels as well, but when the heart is resting in between beats.
• The ratio of light absorbed at systole and diastole is translated into an oxygen saturation measurement.

This measurement is referred to as SpO2. Diagram of Operation Principle:

Operation Instructions

1. Install two AAA batteries according to the Battery Installation instructions.
2. Place one of your fingers into the rubber opening of the pulse oximeter.
3. Short press the switch button on the front panel to turn the pulse oximeter on.
4. Keep your hands still for the reading. The hand should be rested on the chest at the level of the heart. Do not shake your finger during the test. It is recommended that you do not move your body while taking a reading either as it will sway results.
5. Read the data from the display screen when the waveform is steady and forming a consistent pattern. This is the optimal value for measurement. 120/80 is considered normal for blood pressure, but this may vary. For adults, a normal pulse is 60-100 beats per minute, but this may also vary. Speak with your doctor about any concerns.
6. The display modes are as follows:

Notes

1. Short press the power button to switch the display modes.
2. Long press the power button to adjust the brightness of the oximeter. There are 10 levels of brightness. The default is level four.
3. Take out your finger, the screen displays “Finger Out”. It means the measurement has ended.

Front Panel

Notes

1. The pulse bar less than 30% indicates signal inadequacy and the displayed SpO2 or pulse rate value is potentially incorrect.
2. If the screen displays”?”, it means the signal is unstable, please take out your finger and put it back in the oximeter then keep your hands still and retry.

Battery Installation

1. Slide the battery door cover horizontally along the arrow shown in the picture.
2. Install two AAA batteries into the battery compartment. Match the polarity of the compartment. If the polarities are not matched, damage may be caused to the oximeter.
3. Close the battery door cover.

Notes

• Please remove the batteries if the pulse oximeter will not be used for long periods of time, as corrosion can occur.
• Please replace the battery when the power indicator starts flickering.

Using the lanyard

1. Thread the thinner end of the lanyard through the loop.
2. Thread the thicker end of the lanyard through the threaded end before pulling it tightly.

Warnings

◊ Keep the oximeter away from young children. Small items such as the battery door, battery, and lanyard are choking hazards.
◊ Do not hang the lanyard from the device’s electrical wire.
◊ Please notice that the lanyard, which is tied to the oximeter, may cause strangling due to excessive length.

Inaccurate measurements may be  caused by

1. Significant levels of dysfunctional hemoglobin (such as carbonyl – hemoglobin or methemoglobin).
2. lntravascular 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 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 person has hypotension, severe vasoconstriction, severe anemia, or hypothermia.
9. he person is in cardiac arrest or is in shock.
10. Fingernail polish or false fingernails.
11. Weak pulse quality (also known as low perfusion) .
12. Low hemoglobin.

Maintenance and Storage

1. Replace the batteries in a timely manner when low voltage lamp is lighted.
2. Clean surface of the fingertip oximeter before it is used.
3. Remove the batteries if the oximeter will not be operated for a long time.
4. It is best to store the product in -13°F -158°F (-25°C-+ 70°C) and,; 93% humidity.
