This everyday medical device is a simple gadget that can save lives!
A fingertip pulse oximeter is a small device that clips onto your finger and monitors oxygen levels in the blood.
One of the many strange things about COVID-19 is that some patients with very low blood oxygen levels (which require medical treatment) aren’t always aware of it. They may not feel particularly unwell or have other symptoms of low oxygen levels.
This is where fingertip pulse oximeters can be helpful as they allow people to track their blood oxygen levels at home, and are an important preventative tool for certain groups.
They are used commonly in clinical settings, and have helped people with Long Covid (enduring post-viral symptoms), or those who are more vulnerable to the disease monitor themselves at home.
A pulse oximeter measures your pulse and the percentage of oxygen in your blood, by shining a light into your finger.
Ensure you use your device correctly
To begin, turn the device over and install the two AAA batteries that come included in the packaging. To read your levels, follow these steps:
- Open the clamp.
- Place your index finger into the pulse oximeter and close the clamp. Note that your finger should touch the bottom portion of the clamp.
- Turn on the pulse oximeter by pressing the button one time on the front panel.
- Keep still for an accurate reading.
- Within about 5 seconds, your readings will appear on the screen. You can change the display mode by pressing the power switch. The device automatically powers off after 8 seconds.
If you have any doubt regarding your health always contact your local GP or healthcare professionals to seek further medical advice.
