iProven Blood Oxygen Monitor Fingertip, Oximeter Measures Pulse Rate, Respiratory Rate, Oxygen Saturation (SpO2), and Perfusion Index, including Batteries and a Lanyard.

Oh the product seems to work fine so far, One big point, normally when inserting batteries the negative goes to the spring and the positive to the clip. So when I first inserted the batteries it did not work and I noticed other people had returned their item because it wouldn't power on. Well I got the flashlight out and looked at the stamped positive and negative on the inside and even though it doesn't seem to have normal insertion i.e - to the spring. If you insert the positive side to where it says positive and the negative to where it says negative The unit does work fine. I still have to review all the extras that come with it but the oxygen and beats per minute work fine. Update this post if I find anything negative about it but so good so far

An excellent device, and one I have used extensively in my work as a Certified Medical Assistant and EMT-B. The ability for it to estimate respiratory rate from the pulse rate (something that is reliable as a guideline, for someone who is not in any kind of distress or in an emergency) is a great time saver, and will give you a good idea as to how accurate you are if you are also taking respirations by sight. I definitely recommend this product.

This oximeter is the best one I have had so far! When i had respiratory failure about 3 years ago, the hospital gave me one which was ok. It did not last very long. I bought another theu CVS and it was fine, but when it died I decided on the iProven in Amazon. So far it's working beautifully and has a couple more features. One being a hemoglobin tracker of some sort. Very much worth the $. Which is very reasonable

Dr said to get one to track my oxygen levels. This does that and more. A very valuable tool to have

Such a good product! The string that comes with it does not seem to fit anywhere that I could see. Also, the directions are in super tiny subscript that you cannot even see with a magnifying glass. Overall works well, but needs to have better directions so we can see how to fully use it. It does come with a nifty little solid bag to put it in.

The media could not be loaded. Using this item immediately after it arrived was not meant to be, at least for me. I have an irregular heartbeat so I was anxious to begin using it right away. But I experienced the same trouble other reviewers have reported...it would not turn on.I replaced the supplied batteries with my own known good batteries but that did not help. The unit was constructed so well that I doubted it could be defective. Was I doing something wrong?I contacted the manufacturer. Within just a few hours I received a reply with very helpful tips. From their reply I was able to see clearly that I was not inserting the batteries correctly. Note my image showing the correct placement of batteries.Be aware that this oximeter does not accept NiCad rechargeable batteries. The voltage they deliver is slightly lower than what alkaline batteries supply. You will need to use only alkaline batteries in this device.Now I use my OXI-33 every day and I am truly pleased with its performance. It displays everything I could wish for. Plus it is a very sturdy instrument and will likely last for years. When I needed support they were very courteous and very helpful. This oximeter is well worth the money I spent.

I like this brand!!! This is much better then less expensive brands I have bought in the past. Love it & has a great case

I love this product! Works well and use it at work all the time.
