What is a Pulse Oximeter?

A Pulse Oximeter is a device used to perform the diagnostic procedure known as Pulse Oximetry.

Pulse Oximetry is a way to determine the percentage of haemoglobin (Hb) that is saturated with oxygen.

This oxygen saturation (SpO2) measurement is an estimate of how much oxygen the blood is carrying as a percentage of the maximum it could carry and is sometimes referred to colloquially as the "sats" reading.

It is a non-invasive technique which means there’s no need to actually take a sample of blood to perform the procedure, so there’s No Fuss and No Pain.

Handheld Pulse Oximeters vary tremendously in design, size, appearance and price.

Fingertip Pulse Oximeters are the smallest and generally the cheapest but fundamentally all of them perform the same basic function of displaying the oxygen saturation and pulse rate measurements.
