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

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.

I've used the EMAY 80 twice now, and am very pleased with it's functionality as a recording oximeter. First, the unit itself records O2 consistently through the night, so I think the data generated is valid. It is slightly uncomfortable when worn all night, but quite tolerable, as you will probably be using it only infrequently. It also comes with a band that wraps around the finger to prevent the oximeter from falling off your finger, and it accomplishes that task. The most important aspect however is the recording an reporting of the data, and it does this extremely well, especially at this price point. Though it doesn't completely replicate a clinical sleep study for apnea, it comes close enough that you may be able to avoid having to spend a night in the sleep lab. It is quite easy to download the data from the device to the EMAY app on your phone via bluetooth. The app converts the data to a useful chart which provides the important ODI or Oxygen Saturation Index which can be used to define the category of your apnea, and tells you if you need to take measures to decrease your obstruction, or to seek medical attention for a further treatment. In addition, you can also download the raw data from the EMAY app to your computer. Then, you can analyze the data with the OSCAR app which is open source, and can store your data for comparison over time. Anyway, I highly recommend the EMAY 80. It's worth every penny of it's price and then some!

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.

The monitor works well. The phone app is easy to install and works as advertised. The monitor stays on my finger better than I anticipated. My only issue is that it's not rechargeable. That's why I tried to send it back, I didn't notice it in the description.,

I'm pretty impressed with this device. I've had 3 similar BT Pulse Oximeters. The first one the display gave out, the second one the BT failed to pair after about 6 months, and this is the third. This is a quality product and surprisingly, the software that comes with it along with the ability to record the data and export it was the tipping point for my purchase. It's about twice what you'll pay for a cheap one, but it works great and the software allows not only a summary report export, but you can also export the raw measurements to OSCAR (professional analysis) software.

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.

The EMAY EMO-80 is a recording pulse oximeter with built-in data storage and alarms. It supports both continuous recording and spot checks of SpO2 and pulse rate (PR). The oximeter can sound alerts for preset SpO2 and PR thresholds. A free app is available for downloading, analysis, and sharing recorded data. Both iOS and Android smartphones and tablets are supported. Recorded data can also be exported to OSCAR software. The oximeter requires two AAA batteries, which last 24-30 hours (approx 3-4 nights of continuous recording). The device is accurate, easy to set up, and simple to use, and a clear, concise user's guide is provided. The oximeter and associated app support multiple users. I have complex sleep apnea, a combination of obstructive sleep apnea and central sleep apnea. I am currently using BiPAP therapy, with good results. The EMAY EMO-80 is a good tool for judging the effectiveness of the therapy. I pay particular attention to oxygen desaturation values, which are provided in the Summary Report in the app for the EMO-80. I cannot emphasize enough how easy it is to use the EMO-80 and associated app. The device is reasonably priced, and the insights I have gained from using the oximeter have been valuable.

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.

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

I was getting weird readings on my Apple Watch of low SP02 at times during the night. This only records a snapshot every hour or so, so I got this pulse oximeter so I could actually see what was happening. It's easy to set up and use out of the box. It takes 2 AAA batteries and using a decent brand, I get about 10 nights use of this. It stays on securely with the strap overnight and it's very easy to synch it straight to the app in the morning and will hold 40 hours of recording, but synching it every morning clears the memory on the device and transfers everything safely to the phone. The reports are very detailed, you get a summary graph and a second by second breakdown of readings that you can export to excel. It does have an alarm on it that you can set to trigger at a level you choose, it comes preset at 88%. It is loud enough to wake you, most of the time. In a really deep sleep you might not hear it, or at least not register that you have. This has proven that my watch was indeed picking up low readings. I have been able to generate reports that show my sleep with the alarm both on and off and it does seem to indicate the alarm does mostly wake me before it drops too low. The hardest part of all this is actually getting a doctor to take a look at it, thankfully I have private cover and was able to send a selection of reports over and then call them to discuss and get the appropriate next steps started. This device could save your life. I had no reason to think there were any issues with my sleep, so I have to give the Apple Watch some credit for at least for making me aware, but this pulse oximeter gives you the hard evidence you need to show someone when something is off. Well worth the purchase price I feel.

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!

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.

Didn’t have any issues setting it up. Has a good polling rate and helped figuring out a health issue im currently getting diagnosed.
