The Beurer PO 45 is a somewhat more extensive and very accurate oximeter, which measures not only blood oxygen levels, but also heart rate and perfusion index (PI). Measuring with the PO 45 is very simple and completely painless. All you have to do is clip the oximeter on a fingertip and it starts measuring right away.

The Beurer PO 45 is small and compact and has a clearly readable OLED screen. It has 7 different display options and the screen brightness can be adjusted. This way you can also use your SpO2 (oxygen saturation), measure heart rate and PI. If a measurement fails or has not been performed correctly, this is immediately displayed on the screen. The Beurer PO 45 comes with a belt pouch, so that you can easily take the oximeter with you during a long (mountain) hike.

The oximeter is especially suitable for people with asthma, COPD, Covid-19, Lung Covid, heart failure, chronic obstructive pulmonary disease and other respiratory diseases, but can also be used for other purposes, such as sports. The Beurer PO 45 can also be used at great heights, for example when hiking, mountaineering or skiing.
