The iProven Fingertip Pulse Oximeter is a digital monitor that 

measures the level of oxygen saturation of haemoglobin in the arterial 

blood. The monitor detects signs of low levels of oxygen in the body. 

It measures the pulse rate in beats per minute, and also displays a bar 

graph that illustrates the strength of the pulse signal.  

The OXI-27 is intended for sport and aviation use only. It is intended 

for use on children above four years old and adults whose weight is be 

between 15kg and 110kg.

The device should be used in the home/domestic setting only, and is 

not intended for continuous monitoring. 

This device is intended for non-invasive measuring and monitoring of 

the oxygen saturation of haemoglobin in arterial blood and the pulse 

rate in beats per minute. 

•  Measurements may be inaccurate in the following situations:

•  When you’re moving your fi ngers
•  In a very cold environment 
•  When your fi nger isn’t placed properly into the device (see 

above)

•  Excessive ambient light, such as a fl uorescent lamp or direct 

sunlight, may aff ect the result

•  Enamel or acrylic fi ngernail polish or other fi ngernail applications 

may give inaccurate readings

Q: How do I clean the device?

A: You can use medical alcohol to disinfect it. Please use a soft cloth to 

clean the whole unit. Don’t use any abrasive or volatile cleaners. 

Q: How can I replace the batteries? 

A: Open the battery cover. 

Insert the batteries according to the polarity indications.

Close the battery cover

Q: When do I replace the batteries?

A: - Low battery sign shows on the display. 

- The LED display dims.

- When powering on the monitor, the LED display doesn’t light up.

Q: How do I attach the lanyard?

A: Put the thin end of the rope through the hole. 

Then put the thick end of the rope through the loop, and pull the end to 

secure it.

1.  Open the clip and place your fi nger inside the oximeter. Make 

sure your nail touches the upper part of the clip, see image

2.  Press the button and wait for 10 seconds
3.  Read your saturation level and heart rate from the display

1.  Try to breathe more slowly and more deeply. In through the nose, 

out through the mouth. Guess you heard that before. But being 

aware of your respiration can already improve its quality!

2.  Add green to your world! Consider buying some (extra) plants. Open 

your window more often. Take a walk in the park. Being in the green 

can improve your oxygen levels. It will also help you to feel more 

relaxed. Which will help you to breathe more deeply, and as said, 

that can also improve your oxygen levels!

3.  Stay hydrated! The O in H2O stands for the oxygen molecules in 

water. So drinking water will help to keep your oxygen levels up. 

Hydrating yourself has quite a few extra benefi ts. It can help to fi ght 

fatigue. It may keep a headache away. And it can even help you to 

lose weight 

Oxygen saturation indicates how much oxygen the blood is carrying 

as a percentage of the maximum it could carry. Red blood cells 

contain iron-containing protein haemoglobin. Haemoglobin (hb) 

attaches oxygen to the red blood cell and carries it through the body. 

1 haemoglobin molecule can attach up to 4 oxygen molecules. If all 

the haemoglobin molecules are carrying 4 oxygen molecules, it is said 

that you have a saturation of 100%. A healthy person with healthy 

lungs, breathing air at sea level, will have an oxygen saturation of 

between 95% and 100%.
