What does a pulse oximeter measure?

A pulse oximeter is a non-invasive, pain-free skin test using a sensor. It measures a patient’s level of oxygen in their blood. The results are shown as a percentage.

What is a normal blood oxygen saturation level?

According to BLF, a healthy person has a 94-99% blood oxygen saturation level.

What is the average pulse oximeter price?

The price of a pulse oximeter ranges between £50 and £250, depending on the features that are right for you. 

What is the best pulse oximeter?

One of the best pulse oximeters on the market is the Nonin 9550 Onyx II Finger Pulse Oximeter. It boasts clinically proven accuracy in the widest range of patients and settings. It’s long-lasting, allowing for 2500 spot-checks or 21 hours of continuous use.

How accurate are oximeters?

Pulse oximeter readings are accurate and fast. The majority of oximeters provide a reading that is 2% above or 2% under what your oxygen saturation would be if it was acquired from an arterial blood gas test. For example, if your oxygen saturation reading is 94% on the pulse oximeter, it will probably be between 92% and 96%.

What can affect an oximeter reading?

While oximeters are reasonably reliable, there are a few things that can impact this accuracy such as, nail varnish, fake nails, poor hand circulation.
