Review on Track Your Oxygen Levels And Heart Rate With IProven Fingertip Pulse Oximeter – Includes Battery, Case, And Lanyard In Blue by Jason Mitts

This is a good, easy to use device you can keep at home for some self-diagnosing. It is especially good to have during this pandemic as a first step in assessing your condition if you are having breathing issues. It isn't a substitute for a professional diagnosis. But it is a simple, lightweight, painless device that you can use to monitor your oxygen levels and heart rate. I recommend.
