Home medical devices
When we explain how a device such as a thermometer or a pulse oximeter works, we describe the general principle. Individual devices differ, and readings can be affected by how and where they are used. Follow the manufacturer's instructions and the guidance of your health professional, and do not make medical decisions based on our explanations alone.

We work hard to keep every article accurate and sourced, but science and products change and mistakes can happen. We make no guarantee that the information is complete or current. Links to other websites are provided as sources or for further reading and are not endorsements.
