- The pulse oximeter display shows the percentage of oxygen in your blood. For someone who’s healthy, blood oxygen saturation level will be around 95–100%. If the oxygen level is below this, it can tell you that there is a problem. People with low oxygen levels may need oxygen or other treatment.

Pulse oximetry is a test to measure the level of oxygen in your blood. This is called your oxygen saturation level. It’s a simple, painless test that uses a sensor placed on your fingertip or earlobe. Having a lung condition may mean your blood oxygen levels are lower than they should be. Pulse oximetry can help to understand if you might have a lu...
Nail varnish or false nails can block the light and affect the test. You’ll be asked to remove them on one finger only. This will help get an accurate result. Pulse oximetry results can also be affected by medical conditions including anaemia and Raynaud’s syndrome. Talk to your healthcare professional if you have other medical conditions.
You will have a small device called a pulse oximeter clipped to your finger or earlobe. This shines light through your fingertip or earlobe. It works out how much oxygen is in your blood.
A pulse oximeter measures how much light is absorbed by your blood. This shows how much oxygen is in your blood. The pulse oximeter shines two lights through your fingertip or earlobe: one red light and one infrared light. Blood containing lots of oxygen absorbs more infrared light. Blood without enough oxygen absorbs more red light.
Home-use pulse oximeters are available to buy online and in pharmacies. However, these can sometimes give poor measurements as they are not as good quality as the ones used in hospitals. Pulse oximeter results on darker skin may be less accurate because they can show a higher reading of oxygen level in the blood. If you have darker skin and have be...

Jun 3, 2024 · Oxygen saturation, or "O2 sat" for short, is a measure of how much oxygen is in your blood. For most healthy adults and children, a normal oxygen saturation level is between 95% and 100%. Hypoxemia occurs with lower levels of oxygen in the blood and can lead to complications or even death at dangerously low levels below 90%.
What pulse rate or oxygen saturation level is right for me? When you use an oximeter to measure your pulse rate and oxygen levels you can compare these numbers with the numbers that are usual for you. You will find this information in your Keeping My Chest Healthy Care Plan.
Exertion oximetry (under the supervision of a clinician) is used to pick up desaturations and for better early identification of those at risk of significant deterioration. It is particularly useful for identifying ‘silent hypoxia’ (low oxygen levels in the absence of significant shortness of breath).

Your oxygen level (measured with the pulse oximeter) is consistently 92% and under; meaning more than once within an hour. AMBER - At higher risk, phone your GP or 111 for urgent medical attention if you have the following readings: Oxygen level (measured with the pulse oximeter) is 93-94%
What is a pulse oximeter? 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 smart watches or phones which make less accurate readings by reflecting light off the skin.
