Zacurate 500BL Fingertip Pulse Oximeter Blood Oxygen Saturation Monitor with Batteries Included (Navy Blue)ClimatePartner certified

The media could not be loaded. I purchased this Pulse-Ox in mid 2020 as a precaution during covid and did not think much of it until I was recently diagnosed with a minor heart defect that causes me to have random bouts of SVT.Opting to keep it in my purse fir emergencies, I had no idea how helpful it would be until I had a cardiac emergency the other day.When this happens, my HR typically goes into the 260's, so I was not surprised when it wouldn't register, but once it got down into 230-240 range it did register!PLEASE KEEP IN MIND, NO ONE'S HR IS INTENDED TO BE THAT HIGH AND MOST PULSE-OX WON'T EVEN READ BEYOND 200's - SO I FELT IT WAS IMPORTANT TO UPDATE MY REVIEW HERE ON AMAZON.I am truly impressed that this device - not only has it lasted nearly 6 years, but it was also accurate compared to the professional equipment used on me by the paramedics.This device has really helped my gauge when I am in need of rescue medication vs 911! I would say it is the best $ you could ever spend if you have chronic problems with palpitations.Side note. This device came with a nice, gray, ribbon style/clip lanyard that I replaced with a smaller (light blue) wristlet. The lanyard it came with is still in tact, but I opted for the colorful one as a preference. Just want to make mention that the blue wristlet actually came with a silicone remote control cover for my Vizio TV that I placed on the pulse-ox instead.

I like this oximeter very much. It stay on my finger and continues to measure my oxygen for as long as I leave it on.It is also silent. My dog is freaking out because of all the beeps and boops from my new equipment. Having the ability to measure without alerting her is wonderful

I initially bought the Zacurate 500BL Fingertip Pulse Oximeter on a recommendation, thinking it would be a handy device to have at home.

The included batteries are a convenient touch, allowing immediate use right out of the box.Over time, this pulse oximeter has proven to be an essential device, offering peace of mind and dependable monitoring. This tool is a must-have for home health checks. It is a small device that one can carry in your pocket. It is accurate, easy to use and essential for health monitoring. Highly recommend for anyone looking for an accurate and easy-to-use pulse oximeter!

It doesn't work if you have fingernail polish on or if your fingers are the least bit cool. Otherwise, they are good to have around when you don't like drinking water.

I really like the fact I can now check my oxygen level. My daughter in law, who is in the medical profession, has one and when I am at their house I check myself. Now, I can do it at my own house...I am glad I bought this

I bought this for my friends mother who was recently at the hospital with a fast pulse issue. She now has to check her pulse regularly. This is perfect for her and calms her fears. She can even do breathing exercises and watch her pulse go down. Fantastic little gadget!

This worked very well. It was needed for an extended period. Each time we went to the doctor it proved consistent i.e… always two points below the medical center’s reading. We simply added 2 points.

I'm well pleased. It allowed me to feel more comfortable while having an upper respiratory infection. With feeling like I wasn't getting enough oxygen it allowed me to not be as anxious. If you have acrylic nails, heavy nail polish or very long nails it may not work as well. I had no problems with having 95% or better blood oxygen but didn't know this until reading the accompanying material.
