EMAY Sleep Oxygen Monitor with Built-in Recording Capability | Track Continuous Blood Oxygen Levels & Pulse Rate Overnight | Provides Sleep Report & Raw Data

I recently started using oxygen therapy while sleeping due to my saturation levels dropping dangerously low as indicated by two sleep studies. However, once I started oxygen, I had no way of knowing if oxygen levels were improving without another sleep study. So after reviewing numerous sleep oxygen monitors, I purchased the EMAY Sleep Oxygen Monitor due to its built-in recording capability and price, although there were less and more expensive monitors. After receiving it, it was easy to set up the monitor, download the app and then download the results from the monitor. The results showed my saturation levels during sleep were within normal limits, which was very reassuring to me. The app made it easy to read the results and with the ability to save, print and share the results with my doctor, makes this monitor an important tool in my oxygen therapy. I compared the instant oxygen saturation readings from this monitor with my other finger oxygen monitor that doesn’t have the recording capability and the saturation reading was identical, so I have confidence in its accuracy. Highly recommended.

I was wrongly diagnosed with sleep apnea. I was looking for something that records and produces data overnight because the sleep equipment was providing no benefit and degrading my sleep. This device was exactly what I needed. For quick checks, you can use the onboard display. It shows a live pulse trace, the oxygen level, and pulse rate. It is bright clear and easy to read. The values track well with my fitness watch, and if they are a little different, this is the one I trust. This is what you get with any SPO2 sensor. If you want to get data recorded over the course of the day, or in my case overnight, this seems to be unique in the price range. As far as I can tell, all other devices under $180 require your phone to be running and recording continuously while you are gathering data. This device records its data internally for up to 40 hours and you turn on the app only to download and print or store the data. Being able to share the data is why the app needs access to your files. It allows you to generate a well formatted, detailed, summary report save and it as a PDF. You can share it with you heath care provider, or in you records if you want. This is a legitimate reason for access. It is not so China can look at your pictures. Logically it is pretty safe. You can set the app to have access when running, and you only need it open to sync the data and look at or export it then shut it off. The other similar model have the app open the whole time you are recording and give a much larger window for mischief. The company states and I believe, that there is no data taken from you phone and stored on a server somewhere. The data is yours alone unless you decide to send it somewhere. The app is clean and simple. It lets you select a session from a list, organized by date and duration. Then you can scroll through your data on a second by second basis. It displays a graph with accurate with adjustable thresholds clearly shown on the scale, and with the values of the second at the red vertical line shown as text at the top of the screen. Another thing that some may want to nerd out over is that you can export the raw data in CSV format. It saves three data fields, the sample time, the SpO2, and the heart rate, for every second during the recording so you can import and analyze it in anyway you want. The battery life seems to be good, probably aided by the fact that it does not need to maintain a Bluetooth connection when you are recording data. This is a device and app that was developed by smart technical people to provide clear accurate data, in about as useful form as I can imagine. I mean that as a pretty big compliment.

I'm very pleased with this device. I researched several at price points between about $60 to $250. This was the cheapest one of those I compared. I decided to try it before going up in price. The setup was quick and easy. Started it at 11pm right before bed assuming I'd get annoyed and wait till morning when I had more energy and brain power, but it was refreshingly easy to get going. The finger grip is comfortable. I replaced another oximeter of the same style but that didn't record and this one was noticeably more comfortable the instant I put it on. I don't need the extra strap, this stays on just fine by itself. After 9 hours of sleep there is just slight discomfort on my finger pad from having it squeezed all night. The next day, the downloading of the data and obtaining of reports was just as quick and easy as the set up the night before. As I use the app and device I am pleasantly surprised by features that are both user friendly and also handy additions. For example, a quick press of the front button will rotate the display so depending on how you tend to hold your hand you can quickly rotate the readout to see it easier rather than having to contort your hand. It just seems like they actually put quite a bit of thought into all aspects of using this. The report is a handy one page summary of the recorded events. You can even add your own notes to the recording which is really handy when it comes to testing and tracking sleep methods that may improve or worsen your events. You can change the oxygen and pulse thresholds to suit your known physical condition. For example if you expect your oxygen to be between a certain high and low, you can set that, and you can set it to alert you at the low. The default low is at 88%. You can turn the alarm on or off. You can add users which I can see being handy if someone else in the house starts having issues. This is already here, ready to go, and the new user can be added without muddying up the data of the original user. My only complaint is I wish this unit were a usb rechargeable one. The gobbling up of batteries will be annoying. I bought a quality brand recharger with batteries and am hoping that will make this more sustainable and I won't have to be forever buying batteries. But, that did add 30 bucks to the cost of this unit. They do provide 4 disposable batteries with the initial unit which helps. My first pair of the disposable batteries, after one full night of recording, still shows full power, so it'll be interesting to see how many nights they last. Overall I'm very pleased with this unit so far. The ease of use (which is so ridiculously uncommon in tech these days) and quality of reports for such a low price point option makes this unit a definite winner. I'm glad I tried this route first before the $200 options and I'd definitely recommend it for someone wanting to track their oxygen and pulse at night.

My dr actually suggest this brand as he uses this himself at home. I find the price to be fair It has been an important tool for me to keep track of oxygen issues. It has been valuable tool to give my pulmonary Dr recordings. It appears to have accuracy close to High grade medical equipment. All the stats are also very close to my in clinic sleep studies. It stays on finger somewhat OK. It is kinda uncomfortable to have a device hanging on finger all-night but it doable. There are two models. I would definitely spend the extra money for the rechargeable one. The other model goes through batteries fast. With batteries it records all-night for only a few nights. I'm happy with this device and would recommend and would buy again.

Im disappointed in this oximeter. This is the third one I've purchased from EMAY. The first one I bought was in 2021 I believe and it was amazing. It was plug in chargeable which is a huge Plus, this one requires batteries that you have to change out every few days. The first one I bought also had an alarm for both oxygen and pulse rate. But most of all, it is alarming how this model that I just bought is not accurate at all. The first time I used it I had it on for about an hour and it said that my oxygen was at 100% the whole time. I know this is not true because I have diagnosed problems with my oxygen and what's called primary apnea( not obstructive) so if I lay down even to just lay there and relax with out sleeping my oxygen levels go below 90 and even into the low 80s. I compared the two and I tested this out with my handy dandy oxyimeter that was giving to me by a nurse when I was in the hospital after a major car accident. And you can see from the picture that the difference is huge. 5 to 6 point difference is not acceptable in an oximeter. If your O2 is in the '90s all the time, that's not that big of a deal but when your oxygen gets down into the '80s that's a huge deal. There is a big difference between your oxygen levels being at 88 when you're asleep and 82. I do have an oxygen concentrator that I use and wear when I sleep, but I like to wear the oximeter when I'm taking a nap so I don't have to turn the machine on. I'm just disappointed because this used to be such a good brand and now it's just trash. The left is the EMAY, and the right is the Reli on brand, which doesn't have an alarm otherwise I would use that one. I also want to point out that when I was reading through the fine print it states that this is not for medical use. It's for aviation and something else I forgot but anyone can read it and find it. I find this ridiculous because an oximeter is for medical use.

What other reviewers said is true - it fits tight, and is definitely annoying when you go to bed. I felt like my pinkie was in a clamshell and the clam didn't want to let go. Very uncomfortable. BUT, read on... About the Retrofit: Looking for a solution, I rolled up two very small bandaids into little "bandaid cigars" and inserted one on each side of my inserted finger (alongside my finger) which provided a slight (very slight) "opening" of the clamshell to support my finger. When I did this, it worked well for comfort, I did not feel like my finger was squeezed an a clamshell all night long, and the device still recorded my data even with the retrofit keeping it just a tiny bit less tight. The key here is to insert a little extra padding on the white edge where the "clam" closes -- vs. a lot of bulk -- just a hint of extra padding so your finger isn't squeezed so tightly. If you opt to ry this, just make sure it's still recording data (look for the blinking light). If it's not, you've payed it open too far and it's not picking up a reading. About Keeping it on all night: It fell off once during each of the 2 nights I used it (I reconnected it when I woke during the night - then it continued recording data). So far I have not used the velcro strap designed to help keep it on - haven't found that necessary - I don't move that much during sleep. Finger choice: My physician friends told me any finger works for reading your data, so the choice is yours. I put it on my left pinkie since I'm right-handed and it's convenient to have a hand free during the night. Connecting & Reporting to the App: Setting up the app was super easy. Not entirely sure how to make sense of the report it spits out into the App, but the data looks clean and the graphics are pretty simple, so I'm sure I'll figure that out. Batteries: It's an energy eater - you need to replace the batteries (2 AAA) every 3 nights or so. I use rechargeable, so it's no biggie. Rechargeable batteries and chargers have come down a lot in price the past decade or so, so it's the way to go. Rechargeable batteries require special recycling, so don't throw them in the regular trash give them to your local recycling center. So far, happy with the purchase. It's nice to have a pulse ox that records data.

I am giving this unit 5 stars because it performs well the function it was made for despite its low price and for my own purpose. I like the way the unit is able to store data, which can then be uploaded next day (unlike other units that require you to be connected to your phone and keep your phone on while using for it to record). I love the reports it generates. They are superb. I like that it allows to add users. In general, their phone app is great and very easy to use. I like the little strap that goes around your finger to keep it in place when used overnight. The alarm to wake you up when you go below a certain threshold also works well. I don't use it, but it's a good function to have. However, I have to be honest. The unit is not perfect. Firstly, as any other clamping oxygen meter, it clamps too hard. Sure, if it is only 5 to 10 minutes, the clamping is not an issue but when you want to wear it overnight for 5 to 8 hours, it does hurt! I fixed that issue by following the suggestion of one of the contributors here, where they placed two rolled-up band-aids on each side close to the hinge of the clamping mechanism (see picture) and that takes away the pressure from the finger. That worked for me. Now it is comfortable to wear for as long as I need to. Another thing you should be aware of is that the unit does not take measurements continuously but every few seconds; therefore, it is possible that it might not catch some of the lows. You can see this when you wear other oxygen meters at the same time and then old your breath. You will notice that those oxygen meters will show a gradual decrease when you hold your breath. But the EMAY Sleep O2 monitor will show high and then show a quick and sudden drop and similarly when you breath again, it will go up fast back to normal levels, unlike other O2 meters, which will show a gradual increase. For me, this is ok because I just want to see how low my O2 levels get during my sleep and how many low-O2 events I am getting. However, for other folks who want to know, perhaps, how long you remain below a certain threshold, this unit does not allow good accuracy for that purpose.

As both a hardware and software developer, I have to give credit to the manufacturer: this device just works, and it does so intuitively and reliably. It avoids the modern bloat that seems to infect so many consumer products. By that, I mean hardware and software packed with unnecessary features that are not needed, not wanted, or do not work well in the first place. This oximeter strips away the nonsense and focuses on functionality, and I appreciate that. You put it on your finger, press a button, and go to sleep. It is that easy. In the morning, you open the app, press connect, and it immediately transfers the data from the oximeter to your phone over Bluetooth. The app was quick and easy to install, and it is still available on the App Store even for my ancient iPhone 8. From there, the graph is easy to understand and export. My only real complaint is that I wish the graph supported pinch-to-zoom. I emailed the manufacturer with that suggestion. Right now, reviewing the previous night’s data requires scrolling minute by minute through the entire night. A simple pinch-to-zoom feature, like in Apple Maps or Google Maps, would make scanning the data much easier. Other than that nitpick, this is a great product. Used alongside my CPAP machine, it is helping me manage my sleep apnea and improve my quality of life. For $60, it is a steal.

Works really well, with the little strap it stays in my finger all night. The PDF report from the app had good summary including the SpO2 graph and pulse Data can be exported with a second granularity as CSV and spo2 files for thos who wants to analyze the raw data. It will store the data in the sensor so no need to keep it synced with th phone, that is done in the morning when you wake up.

Semplice da utilizzare, di buona fattura. Buona anche la app a supporto.

Omg. This is amazing and can save your life. My smartwatch kept going off saying my o2 was very low, I ignored it as online it said this aspect of the watch wasn’t particularly reliable. This kept happening, I record my sleep on a sleep app and my snores (all night) I’m gasping for breath. I’m not overweight, I don’t drink, I exercise daily and eat cleanly. I went to the dr, showed her my results and she literally laughed at me, dismissed me saying no, these are far too low and sent me on my way. I saw this device when I was looking for help with my night breathing. Bought it, wore it for the first time last night and the results were shocking. My oxygen levels go down to 55%, for 2 minutes they’re like this. This happens through the night as low from 96-55 and in between. This screenshot of the summary was sent to my Gp this morning. The device facts: The app is absolutely outstanding, something you’d expect from a machine of several hundred pounds. It’s detailed to the second which you can easily move through, I had my doubts it would stay on my finger but it did, it didn’t move once. The instructions are incredibly clear, detailed and not translated from another language, the diagrams are concise and easy to understand. I had set an alarm up to go off if my levels went to 92% but this was going off all the time, I easily touched the button, selected off and easy as that. I cannot recommend this more highly.

The function and the app where fantastic. I was impressed by the quality and accuracy of the reporting. It looks like a fully professional sleep analysis. My respiratory doctor was very impressed by the report and it got me out of having to do a hospital sleep study every year. Amazing buy!

It does what it says very well, the device is easy to use and has an interesting display while working. The UI is intuitive to navigate which is a great job considering you do everything with a single button. The data is stored and then you can easily transfer to phone (in my case iPhone) - and then the reports it produces are very useful indeed. The only flaw I have with it is that, for me at least, I cannot get anywhere near a full nights recordings out of it due to it becoming misaligned or something - I do tend to be quite "mobile" while sleeping and presume that's the cause, it *ought* to be stable for most people, the extra band that you can use to secure it does certainly improve things. Regardless of the inability to record full night (which I believe is a "me" issue) - it's recorded enough to show there is indeed a problem, and explains it in the right way for professionals to be able to use. So - job done, and highly recommended.
