The Beurer PO30 measures arterial oxygen saturation (SpO2) and heart rate (pulse frequency).

Beurer pulse oximeters provide non-evasive measurement of arterial oxygen saturation (SpO2) and heart rate (pulse frequency). Oxygen saturation indicates the percentage of haemoglobin in the blood that is loaded with oxygen. Therefore, it is an important parameter for assessing the respiratory function.

To take a measurement, the pulse oximeter uses two rays of light with differing wavelengths, which strike the finger when inserted inside the housing.

A low oxygen saturation value often indicates underlying illnesses (cardiac insufficiency, respiratory diseases, asthma, heart failure etc.)
