Vet Handheld Pulse Oximeter - Professional for Dogs/Cats/Horses SPO2, Heart Rate, Temperture - Rechargeable Battery (30-Day Guarantee)

So, as configured, it's supposed to be a veterinary instrument. I couldn't see why hemoglobin in dogs, etc. would be THAT different from human, and I have been trying for YEARS to find a pulse oximeter I could put on my ear while doing weights, pullups, etc. where every finger pulse/ox I've been able to find craps out. Anyway, this thing works GREAT! I put it on the ear, a human one on the finger, walk around, run, etc. and they're within a percent or two of oxygen saturation and a beat or two for pulse. The one thing that does not agree is the perfusion index, but I'm not really concerned with that (the human unit reads several times higher than this one, but I have no way of knowing how accurate its number is). The important thing to me was the oxygen saturation and the pulse, which agree as closely as two of my different human jobs do. The thing comes with 94% to 100% SpO2 set as limits for alarm, and pulse of 50 to 130 (at least mine did) which seems pretty human, and is just right for my age. The alarm works great, it gives a tone if you go out of limit range, and a little tick every time your heart beats.I suspect this is rated for vets instead of home medical because it hasn't undergone some sort of certification, not because it doesn't work right. But obviously it IS sold for animals, so buyer beware if you use it otherwise.I see no reason to use it on a human except the issue I have, which is that when using my hands for workouts the finger jobs are not at all representative of what's going on in the body. Maybe because they don't like the motion, maybe because peripheral blood flow to the fingers shuts down in heavy exercise using the hands, maybe both, maybe something else. This thing, clipped to the ear, continues to give reasonable readings, and if I don't breathe enough, alerts me to low oxygen. Which is exactly what I want. So I'm a happy camper.A couple of notes: The clip on probe comes with large silicone sleeves designed (I guess) to hold shaved animal tails, or animal tongues, or some such. I was able to get a reading, just barely, with them on, clipping to my earlobe. A fine reading on the finger. But during heavy exercise they moved enough it gave "sensor error" and quit reading. No problem. Those sleeves slip right off, and you are left with the sensor with soft silicone on it, which clips beautifully on my earlobe and stays in place during the pullups, weight bench, etc. I will mention it clips tightly enough that I felt it for 20 minutes or so after taking if off, if that would bother you.Anyway, it does what I want. It has no printed instructions whatsoever, it has a 225 MB CD instead. My computer does not have a CD reader. That was no sweat for me, because the labels on the buttons are so intuitive I was able to do everything I wanted right out of the box with no instructions. But if you wanted to use some of the fancy features, exporting data, etc. it would probably be an issue.DISCLAIMER: I am making no claim whatever that this works on humans or is accurate on humans. It is not sold for or presumably certified for humans. I would never depend on it for any critical measurement for any medical purpose on a human. But for my purely informational hobbyist use, I like it. It's pricey, but around a tenth as much as any human-certified unit I could find, and since I'm using it for fun instead of for medical reasons, it's good for me. DO NOT use it for any sort of critical medical use on any human. And I make no claim about how it works on animals since I don't have one to test it on.

The oximeter works well on non-hairy parts that are not moving. This makes it difficult to use except for an animal under anesthesia. I have used it several times, but it is technically hard to get reliable readings, and impossible to get consistent reading except with anesthesia. Anesthesia is a very important use, for certain, but if your pet has heart of lung disease, it is difficult to use the monitor to measure the animal's oxygen saturation, and therefore difficult to adjust the amount of oxygen needed to be administered.

Worked great during my externship. This product has a great price and came as described.

I got it for a week only, but it works well. The preferred place to get the reading all the time is the lip.

Ordered another one just like this from a different seller and the rechargeable battery was included, this one didn't come with one and goes through batteries like crazy.

Frequently does not work and bpm cap out at 250 bpm. I believe this is a device for humans that is rebranded for pets by just including different cord adapters to take O2 readings.I spend significant amount of time trying to get a reading on my pet, this is not ideal.

Works great. It can be used in a big variety of animals. From dogs to chicken. Very big heart rate range (up to 450 bpm)

I had minor issues at first with o2 reading on the ear. Then I used rubbing alcohol on the back of the ear no issues.
