What is a Pulse Oximeter?
This year, researchers at the University of Washington at Seattle found that of hospitalised patients with Covid-19, those with low blood oxygen saturations were 1.8 to 4.0 times more likely to die in hospital. This led many people to purchase pulse oximeters for use at home to check their blood oxygen saturation.
A pulse oximeter is a non-invasive device that can be used to measure the saturation of oxygen in the blood. They are easy to use and can be used by anyone, even people who aren’t medically trained.
In this article, we’ll cover how a pulse oximeter works and what they are used for.
