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

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.

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.

Amazing product for the money! Worn it first night, stayed on with no extra finger strap. Easy to use. Instructions incredibly good, clear, comprehensive and carefully written in large writing! Easy to download and connect app. More than 5 stars

Initially cynical about this gadgets accuracy and precision I was pleasantly very surprised at both. I used it for 4 nights initially to find out if it was likely I had sleep apnoea sleeping on my front. Recording both my oxygen levels and my heart rate throughout the night. A low heart rate whilst asleep was a question that also needed answering so it also solved that issue. Clear concise instructions, very easy to use, 2 sets of batteries and ability to transfer data to the app on your phone or laptop for summary reading and transference to print if needed. The unit comfortably stayed on my finger all night. All in all a great little unit and very happy with my purchase. Would highly recommend.

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.

It works really well and is actually pretty accurate compared to ones at the Hospital rarely being more than 1-3% out. And great for recording during sleep which helped identify my sleep apnea. However its faulty when uploading results, its happened several times but now I am really upset the past 5 days will not load up at all and I have therefore lost some really important Data

This is day 1 set up day. I found reading the instructions (at 72 years old ) Actions and looking at the pictures weren’t very explicit. How ever once I scanned the code and watched the YouTube vid it made sense. I managed to put the strap on. Then came the pairing or binding as the word they use. I must admit I did not read the instructions and it took 5 attempts to realise ( as per instructions) you dont need your finger in the device. 🤦🏽‍♀️ once it was paired I then read the manual accessed the other devices they sell and looked at the cases available. All look good quality and fair prices. So far it might have taken and hour of my life but at least I accomplished something today 👍🏼 I will use tonight and update review tomorrow.

I wore this on one hand and an NHS take-home sleep study oximeter on the other (£1000 device). While the nhs did not give me the full data, the headline ODI and low SP02 point was very similar enough to feel like it can do the job. The device is easy to use and data summary very useful for showing you what is going on and talking to a GP / respiratory nurse. I also found it useful to experiment with diet and sleeping position effects on sleep breathing. The low SP02 alarm is effective and reassuring if to avoid scary 02 drops if things are difficult. The app and printout summaries are very useful. It works with normal AAA rechargeable batteries which I always prefer compared to more expensive models. I am a 3xl and find it comfortable enough to wear every night with just the clip and no strapping. Serves as a useful torch. Screen rotation is also nice feature. Price is good compared to others. It is also regularly put on offer. Review is for deal price <£40.

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

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.

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!

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

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!
