AccuMed CMS-50D1 Fingertip Pulse Oximeter Blood Oxygen Sensor SpO2 for Sports and Aviation. Portable and Lightweight with LED Display, 2 AAA Batteries, Lanyard and Travel Case (White)

UPDATE: Still using this several times a day, and it’s still going strong after over 2.5 years of use. I’ve owned several different pulse/ox devices over the years and I can say that this one is the best of the bunch. I actually came back to Amazon tonight to order a second one so that i’ll have a backup, especially since I’m doing a lot of travel these days, mostly long cruises of at least 21 days. It uses AAA batteries which are easy to find almost everywhere. And it’s not a battery ”hog” -- the first set if batteries lasted about 18 months of daily use, checking my numbers 2 or 3 times a day. AND it’s staying accurate. I’ve taken it to my doctor's office twice a year to compare with my doctor’s pulse/ox and it’s almost always exactly the same or at most 1-2 points lower than my doc’s. It’s still a 5-star item. Original review: This is a newer version of an AccuMed Pulse Oximeter I've been using for several years. It's accurate, easy to set up and use (just put in the batteries), and the lanyard and case make it easy to take along when I exercise or travel. I have severe emphysema, prone to CO2 retention, so it helps to keep tabs on O2 levels when I'm doing anything strenuous so I can take pre-emptive action (specific breathing techniques) before I run into trouble. There are a number of small oximeters on the market and they all operate on similar technology, so it comes down to the quality of the materials used and how it's put together. Some are really junk -- accuracy is whacky, the spring clip gives out, etc. This one is very good quality and built to last. I've been using it for several weeks, usually 2-3 times a day -- more if it's a heavy exercise day -- and I've seen no issues at all. This one's a keeper -- solid 5-stars for accuracy and quality.

I have had it for several days. It is easy to use. Screen is clear to read and it gives the results on a few second. It comes with a case for storage. The instructions are easy to understand how to use it.

Works very well. Excellent workmanship.

Works well and has an active heart monitor that gives you a visual line of the beats. Handy when trying to get a reading off of someone that has fingers that don't read easily.

Does its expected use. Ease to use, seems accurate. Good purchase

This is worth more than the price. Easy to use. Love the lanyard and the case. Even comes with batteries. If you’re in need of an oximeter then don’t wait to buy this!!!!

Great medical device

Works perfectly

Very good product.

This is an excellent tool. I am currently in hospital and can check my oxygen level against the ones they use in hospital. Very good quality I am very pleased with the product.

It has proved very useful as my wife has recently been in hospital after being unable to monitor her oxygen levels more closely

Beautiful plece of equipment and did exactly what its meant to do.
