NHS-approved pulse oximeter FAQs

What is an oximeter?

If you're unsure whether or not you need to use an NHS-approved pulse oximeter, you should always contact your GP or a health professional. As an oximeter is a tool used to help with the diagnosis of COVID-19, monitoring sleep apnoea and more, it's essential that you find out what risks most apply to you and discuss any concerns that you might have.

According to the NHSwebsite, "A pulse oximeter is a small medical device that is put on the tip of the finger, to check someone's oxygen levels. Pulse oximeters measure blood oxygen levels by transmitting light through a finger – they are more accurate than smartwatches or phones which make less accurate readings by reflecting light off the skin."

Are oximeters accurate?

Pulse oximeters used in medical settings or hospitals are high-quality and likely to give you the most accurate reading. Pulse oximeters are available for sale in your local chemist or online for use at home and while they will record your oxygen levels, some can be inaccurate or give poor readings if used incorrectly.

It is important to invest in one that has been NHS-approved, comes from a reputable retailer or has been recognised for its quality. While it may not be necessary for everyone, this gadget could be used by individuals with underlying respiratory issues who may want to monitor or assess the severity of attacks, or physically active people who experience regular drops in oxygen levels.

Things that can affect the accuracy of your test include:

If you are wearing nail varnish or artificial nails

Your skin is thicker than normal

Your hands are cold (make sure they’re warmed first)

If you’re a smoker, the oxygen level shown may be higher than your actual oxygen

You’re not sitting still. Activity can raise your heart rate and decrease your oxygen levels shown, or move the oximeter out of place

Skin pigment can also impact the accuracy of pulse oximetry. Studies have shown that oximeters can overestimate oxygen saturation, so you should check your oximetry readings with your provider or GP if you’re concerned

How to use oximeter at home:

Want to use an oximeter from the comfort of your own home? You can measure your pulse rate and oxygen levels by clipping the oximeter to your fingertip. Once it's attached to you securely, switch it on and wait a short time for the results to show.

If you're still unsure how to get this device to work, the NHS has pulled together a six-minute video to show you how to use a pulse oximeter at home. We love that this video takes you step-by-step on how you can monitor your readings if you've been asked to use one by your GP or health professional.

You can also track your healthy with a smartwatch device for women.
