It is wise to have an Oximeter on hand to measure oxygen levels. Because it works really great! I have ordered two for my parents.

"Battery compartment tricky - otherwise a great medical device.  It does take a few seconds longer to display a reading than other finger pulse-ox devices I've owned."

"This is a good monitor. It reads exactly the same as the doctors office. Display can be rotated in for easier reading, and the brightness is adjustable. I like having the carry case. It does take a few seconds longer to display a reading than other finger pulse-ox devices I've owned."

Got Questions? We've Got Answers!

What is the normal range for pulse rate?

The normal resting range for pule rate is typicaly considered from 60-100 beats per minute. Ask your health profesionalthis question as it pertains to you.

How do I know the battery is low?

The battery icon will display the low power indicator. Please replace the batteries.

What kind of conditions may cause an inaccurate reading?

Cold hands, poor circulation, very weak pulse, movement, fingernail polish and acrylic nails may cause inaccurate results.

How does it work?


Each wave (see image) corresponds to a heart beat and the wave amplitude corresponds to the amount of blood detected. If the wave amplitude is low, this means that your blood perfusion is too low for a reliable read. You should retake your measurement and make sure that your finger is positioned right under the LED lights.
