EMAYSleep Pulse Oximeter with Built-in Recording Capability | Record Continuous Blood Oxygen Levels & Pulse Rate Overnight | Provides Sleep Report & Raw Data

What a great little tool! I bought this to monitor my O2 saturation during sleep. Simple to use, and simple to upload data captured to the dedicated phone app. The phone app produces a report for each set of data showing O2 desaturation, no of episodes, % of time, and a heap of other useful data. It also can show data trends over time. The battery life is longer than expected. Also great after sales support team contacted me after a couple of weeks of use to make sure I was happy with my purchase and if they could help in any way. Compared to other monitors this offered everything at an amazing price. I would definitely recommend!

Better than I thought it was going to be.You'll need a supply of aaa batteries or rechargeable. It eats them. But all on all, I'm satisfied with the product. It reads my oxygen level all night or day. And saves it with a graph on the app

This is a quality product; it is well-made and its functionality is impressive. The Android app which you can install via the Play Store works fine on my Samsung Galaxy Note 20 Ultra 5G and has a well-designed, easy-to-use user interface. The device clamps on a finger like the ones nurses use in hospitals and clinics. It samples SpO2 (blood oxygen level) and pulse rate each second and can store these measurements overnight while you sleep. I simply left the device on my index finger overnight in bed. A roll of black bandage is supplied but I ended up taking it off as the device stayed on my finger all night without it. The red LED light that shines through the finger did not trouble me as it is not bright, and the display itself turns off after 90 seconds anyway. The end knuckle of my index finger was a little sore the next morning where the device had been clamped on my finger, but nothing serious.Although the device has data storage capability, it can be used as a normal pulse oximeter for spot checks as well. To look at it has the appearance of a standard pulse oximeter, albeit the quality of manufacture and materials is noticeably better than a cheap standard pulse oximeter I already have.The device uses two AAA batteries. Four batteries are supplied in the box, as well as a lanyard, a little storage bag for the device, and a user manual. The user manual explains well how to use the device, and there is an e-mail address to contact the manufacturer if you have any questions or problems. I e-mailed the manufacturer with a query and they replied quickly and were helpful.The user manual estimates that a pair of AAA batteries should last for at least three 8-hour measurement periods.It is possible to view, save and e-mail a detailed PDF report showing statistics and graphs of the blood oxygen levels and pulse rates over the measurement period you have had the device on a finger. The report is impressive and looks very professional, and I would not have a problem showing it to a doctor. In my case I was worried that my blood oxygen level was dropping too low while I slept, but the report put my mind to rest. It is also possible to save or share a CSV (comma-separated values) file which you can import into a spreadsheet if you want to examine or analyse the data yourself.The only things that I found that could be improved are: a) sometimes deleting the data stored on the device took a few attempts; b) the user manuals that can be viewed in the app could do with being zoom-able, as the text displayed on a smartphone is tiny (a printed user manual is supplied as well in any case); c) I could not find a way of deleting a user. I do not consider these significant problems, though.Overall I am very impressed with this device.

I am happy to report that the Oximeter is working extremely well.I elected for your product specifically because it can record readings continuously rather than most meters which only show a measurement at a specific moment in time.I should explain that I suffer from Obstructive Sleep Apnoea and use a CPAP machine overnight. I hadsuspected for some time that once I was asleep my breathing became very shallow and thus my O2 statsdropped and the fact that I could record this and more download it and send it to my consultant has been most helpful. I am waiting for my next appointment at Leicester when we can discuss the findings and plan accordingly.The only slight issue I have encountered is that sometimes during sleep the normal movement of yourhands can cause the meter to move just enough so that it thinks you have taken it off and the readings stop, possibly an on/off switch that you need to actually switch off rather than an "auto off" would solve this but it is a minor issue.

This little device has been amazing to record my saturations overnight. It gives so much detail I was surprised and is accurate.

The Emay Oximeter was good and accurate till the memory was full. Once the memory is full it said connect device to the app and should show readings in Device Data in the app so you can clear the memory. But nothing showed and tried force connecting it via Bluetooth but still nothing showed in Device Data. I emailed and got emails back from Emay Technical Department but they kept sending me instructions I've already tried. The Device kept saying Device is Full, Please Clear and you can't use it till the memory is clear so it didn't work as intended so sent it back for a refund.

It's lovely to have something as straightforward as this is that does what it says it does. Without pinching tightly or being uncomfortable it stays in place and working all night including trips to the toilet. I suggest you think carefully about which hand is less needed for whatever you might want to do before you plan on taking it off. The hand with it on can still be used as support to help the unencumbered hand. My only minor criticism is that the extremely long record on the app measures time from when it started running. I would like it to say the clock time so that I can see what was happening at a certain time. It only takes a couple of seconds for a reading to appear on the screen so is also useful to get a spot reading.
