Product Information

SpO2 reading A measurement of how much oxygen is in your blood. Every pulse oximeter has this feature, as it's the main thing they're designed to measure. A SpO2 reading of less than 92% (or 88% for those with chronic obstructive pulmonary disease) can suggest someone is seriously ill and needs immediate medical attention. Display orientation Some pulse oximeters give you the option to rotate the display so it's easier to read when the device is on your finger. During the pandemic, some doctors have suggested buying pulse oximeters to test your oxygen levels at home as a precaution, in case you become severely unwell with Covid-19. Trials are ongoing, but if you're unwell, it's important not to rely on these devices without advice from a medical professional.

But if you're after particular features (such as a perfusion index function or a larger, OLED screen), the extra functionality will usually cost you more. Pulse oximeters are small medical devices that let you keep tabs on key health measures such as your blood oxygen levels and pulse rate at home, and share them with your doctor or clinician if needed. Perfusion index Usually only pricier pulse oximeters will have this feature. It measures the ratio of pulsating to non-pulsating blood in your finger, and is used as an indication of how strong your blood flow is. Most people are unlikely to need this on a regular basis, and we don't test it in our lab.

It's important a pulse oximeter does its job accurately and efficiently, and is easy for you to use and understand. Wear them with: slim indigo denim, a sweatshirt and, if the weather calls for it, a proper winter coat. If you need a pulse oximeter, your doctor will usually advise you to buy one. You might not even need to buy it yourself, as it might be supplied by the NHS, depending on your condition and circumstances. The burgundy shade of oxblood goes with just about any trouser colour, so it’s a great versatile alternative to have in your wardrobe. A pair of classic denim or white jeans work well with oxblood boots, and although the burgundy hue gives an autumnal feel, it can work across seasons when paired with light and white denim.

If you've been told by a medical professional that you should use a pulse oximeter at home, you need to make sure you're using it as effectively as possible to get the most accurate picture of your health. Ensure your hand is warm to the touch, then sit down and let it rest on your chest for about five minutes before switching on the pulse oximeter.
