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

Useful for Judging Effectiveness of CPAP Therapy
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.

A literal life saver!
For months I was waking up with massive migraines, feelings like I hadn’t slept in weeks, fatigued and brain fog constantly. I’d talked with my doctor about setting up a sleep study but they were backlogged. Every day I felt progressively worse and worse. Then I though “I’ll just do my own sleep study, see if I really do have apnea going on”. I ordered this device and was absolutely shocked at what I saw. I knew it wasn’t good, but not this scary! I was dipping clear down to 68% oxygen saturation (65% is where your lips and fingers turn blue). I showed my Mom this first graph and she just happened to have an extra CPAP machine stored away. She got me setup and the first night was incredible! I felt like a new human! (2nd graph). This all went down 2 months before my actual sleep study which confirmed, yep, I have a pretty good case of sleep apnea. I feel like without this tool, I genuinely wouldn’t have survived!As for the device itself, it works pretty flawlessly! It’s comfortable, stays on well through the night and uploads the data to the app with ease. Part of my nightly routine now! Only thing that’s kind of a bummer is how quick it runs through AAA batteries (a set every 8 days or so). I picked up some rechargeable batteries, which I’d highly recommend. Beyond that, solid device, well worth the price! If you suspect sleep apnea (you snore, you wake up fatigued, you have brain fog, mornings are way more rough than they used to), BUY THIS!

Oxygen and pulse readings with percentage
I love this pulse oximeter and the fact you can wear it overnight without interruption. Easy to setup the app and connect the device to the phone app. Easy to download the data and easy to understand. I would recommend this device for anyone questioning whether or not their oxygen and pulse goes down during sleep. I like that the downloaded information can be printed out and given to your doctor.

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.
