Pulse oximetry is definitely not a new technology, and even small, finger-sized portable pulse oximeters have been around for a while. But few have had such a clear display and been as reasonably priced as a the Oxicheck.

This device, like any oximeter shines red and infrared light into your finger to noninvasively check your blood oxygen level and heart rate. It has a nice large LCD display that shows and continuously monitors (not records) your heart rate and blood oxygen saturation in real time. This works off the same principals of larger pulse oximeters that you would find in a hospital.

It’s compact and lets you take it with you just about anywhere running on batteries and needing no cords. It’s a handy gadget to keep tabs on your own health, but don’t let it replace getting checked out by your health care professional. A couple things that can give false good readings with this and any similar devices are low hemoglobin and carbon monoxide poisoning, among others.

The Oxycheck retails at Hollywood gadgets for $139.95, weighs only 1.8 ounces and comes in colors of black or white.
