EMAY Sleep Oxygen Monitor with PC Software & App | Bluetooth Pulse Oximeter Rechargeable for Overnight & Continuous SpO2 Tracking with 72 Hours Built-in Memory | Gives Informative Report & Analysis

I've had a few pulse oximeters, but this one supersedes them all. It does the job, and it's not a hassle at all. Some things that I really like: * Fast readings (and seemingly accurate readings, too) * Clear and easy to read * Long readings (I can wear it overnight easily and still have battery leftover the next couple days.) * Graphs show what's been logged. These can also be sent as PDFs to your email and to your doctor. * Personalization (I think it came with a 94% SPO2 lower reading, but I set mine to 90% minimum for SP02 to match what my doctor's office uses.) * Easy to charge (I just plug it into my computer, and it charges.) * Easy to upload what it logs. Just click "connect" in the app, and it does the rest. The only things I wish they'd do different is make it a little more comfortable. It's great for spot checks, but after a while, I'm ready to take a break from wearing it (but then again, how much can they actually change to make these more comfortable without compromising the accuracy?) Also, after that, after a couple minutes, the "recording" message comes on. I guess I'm nosy in that I want to see what's being recorded. Otherwise, it's my dream pulse oximeter. :)

This oxygen monitor is a top choice for professional use. I rely on it for patient monitoring, and the audible alarm is a game-changer—you can set it to trigger at your preferred SpO2 level, ensuring you’re immediately alerted. The alarm is clear, even through a baby monitor, and the battery consistently lasts around 12 hours, perfect for long shifts. I was so impressed that I bought a second unit for 24/7 monitoring. One of the most convenient features is its simplicity—no app or Bluetooth required, which is a huge improvement over the wrist version I previously used. With no need for constant checking or toggling settings, it frees up time for other tasks, almost like having an extra set of hands. Navigating the settings is intuitive, and the company’s proactive customer support shows a genuine commitment to quality. One minor downside is that, with extended use, it can leave a red mark, so I occasionally switch fingers to prevent pressure marks, especially for overnight monitoring. While the reports are detailed and professional, I’ve moved away from using them as this device’s real-time tracking has become my go-to. Overall, the audible alarm, battery life, and ease of use make this monitor an invaluable tool for reliable, hands-free patient care.

PROS: * Visual display while monitoring is very nice. * Display is crisp and clear. Easy to read. * Device setup is straightforward and easy to do. * Uploading to the PC / phone is easy. * It is very easy to start the recording, to upload data to your phone or to the PC. * I charged the device every day so no problems running out of battery overnight. * The real-time display is GREAT. * I had the opportunity to compare, simultaneously, the SleepO2 and the EMO-90 and they both recorded similar results. * I have tried both the SleepO2 and EMO-90. The EMO-90 is great for watching in real-time, while the SleepO2 is more comfortable for nighttime wear. CONS: * not as comfortable as the SleepO2. Hard case vs. silicon finger sensor. * has a tendency to fall off the finger during the night, this would produce two (or more) files that would need to be uploaded. The files could not be merged. * I was afraid of the monitor falling off my finger when getting up in the middle of the night. The SleepO2 was gently tethered to my wrist. * file management on the PC is a bit tricky. File names require some concentration to determine what was recorded and what was not. * It is possible to upload the same file multiple times, which confused me when I was trying to look at trends. This could be avoided by printing the summary reports. *Some data management tools (Excel spreadsheets, for example) would be nice for viewing the data. It can be done, but it is not for the average user. Maybe EMay could offer some templates or if there is a user group, users could contribute. SUMMARY: * Very nice device, especially handy for real-time monitoring of pulse rate and oxygen level. * Very good quality. * Not as comfortable for nighttime wear as the SleepO2. * To check its accuracy, I will be asking my doctor to do an office measurement, or even better, schedule a home sleep study with a professional machine. I will try to amend my review after that test.

I'm impressed at how this device works and the detailed information I'm getting. I've COPD and Sleep Apnea and use oxygen at night to sleep and off and on during the day. I'm able to wear the finger meter using the strap to keep it on all night. The information on my oxygen saturation and heart rate are great. This unit takes a data point reading of O2 and pulse every 30 seconds from the time I turn it on record until I turn off the record. Plug in the USB cable to my computer and using their App download the information from the finger unit to the App. I can review the data and review a chart version that shows more detail than I every expected. I showed a copy of the charts to my doctor today when I went in for a check up. He knew exactly what they were and explained to me what all the data was showing. He even asked where I got it from. You can even download an Excel file of all the data points if you want to manipulate the data yourself if you want. This has been a great device for me to be able to see what's going on with my O2 and pulse during the night when it's difficult to tell what's going on since I'm asleep. Great unit and well done. It took a little while to get used to the Pulse Oximeter sticking off my finger at night but the little strap keeps it from getting pulled off you finger when sleeping. Will get another one if this one ever fails. By the way this meter has a rechargeable battery that lasts about 8 hours also. Just plug it in a USB to recharge and you're ready to go.

I have had a problem with "tiredness" the last few months. My doctor recommended an "oximeter" to check my oxygen level from time to time and preferable overnight! I shopped around and found this unit at a reasonable price. I have had and used it now for about 3 weeks and find it accurate and VERY informative. It has revealed that on several occasions my oxygen levels dropped very low. They should not drop below 90 and mine were dipping below that. It is described as a "dangerous" situation. One is flirting with oxygen starvation and the resultant problems with heart, brain etc. I already have heart issues so this was very good information. The unit is easy to program and to set the alarm as you see fit. I have mine set to go off if it drops below 80. It is "rechargeable" and seems to have a good battery life for something very small. It has an "annoying" alarm which is what you want to wake you to get you breathing heavier. The only down side and it's not worth taking a star it one of those "me" things. I worry about it slipping off my finger at night. I have acquired some of that "stretchy" tape and it helps secure it to my finger. You can use any finger you want or that will fit into the device. I have suggested to the company they create some sort of "holder" to help keep it steady. It has never slipped off my finger, but it's one of those nagging worries. I will continue to use it till I am told to stop, but will still keep it around for "spot checks" of my oxygen level. I am scheduled for a "sleep study" to see what can be done about this oxygen problem. I should note...I am over 80 years old! So, bottom line, if you are tired all the time...snore loudly or awake suddenly and frantically...might look into this little guy.

The EMO-90 was very easy to set up. It came fully charged and the configuration settings were easy to figure out. I wanted to make sure the alarm was not going to go off and it was all ready set to no alarm sound. The threshold for the alarm can also be adjusted. The QR code for the iPhone app worked and the set up for the account was very quick. The Bluetooth connection was just 1 button click. The reports are great. There is a summary and detail graphs that are easy to read and informative. The report is very detailed. I was clearly able to find apnea event and also how much time the SpO2% was under 3% of threshold and 4% of threshold. For my needs this gives me a better sense of how my CPAP is performing than the app that comes with the CPAP. I would recommend this device for anyone who wants to monitor pulse OX overnight.

Edit: I've worked with this thing almost every night for a year and I hate it. I want a meter I can rely on and this is not it. I kept trying as I want a meter with an alarm. But this meters alarm is garbage. (See comments below). I quit. Off to find something else. Emay: fix your stupid alarm so it's useful. Emay: fix your stupid meter so it doesn't produce bad data. It just said my pulse was 34 for TWO minutes, with the alarm going off. Finally it figured out my pulse was twice that. Junk. Fix it. This error ruins all your recorded data by putting bogus lows into every session Summary: Hardware works, badly thought out software. I bought several O2 meters from this company, as they were cheaper than Viatom stuff. They are about as accurate, but the software's not as good. In fact, it's terrible. The big problem with the device is the software, which makes it a pain to use. Basically, their mobile app seems like a bad port of desktop software that no one has updated for a decade. There is an o2 graph screen, but it's completely useless as you can only show four minutes of data. No, pinch to zoom is not supported, it's a desktop app. Landscape mode? Doesn't auto detect screen orientation like every other mobile app does, it's a desktop app. Push a button. In landscape you get ten minutes. Useless. I need to see the whole night. There's another screen. It produces an 8.5 x 11 pdf because, say it with me, "it's a desktop app". You can't read anything. This page does support zooming, and it does show the whole night. Of course, you can't zoom one region of the that graph, because it's a PDF. All this could be avoided by having a graph with pinch zoom like any other mobile app. THE ALARM The alarm is a nice feature, but it has a lot of issues, and non-obvious behaviors. The alarm goes off if anything is "wrong", including if you don't have your finger in it. This is a huge annoyance, because this means that every time you want to take off the device, you have to first disable the alarm, then re-enable it when you put it back on. And it's a long, awkward process, due to the "user interface" of short and long presses. And you HAVE TO take your finger out to download the data. To turn it off, when it wakens you in the middle of the night, you have to: long push, long push, short push, short push, short push, short push, short push, long push. get anything wrong, and the alarm keeps sounding. And you get to start over. Hope you don't have roommates. Bear in mind, you are trying to do this while being awakened from a deep sleep, with an alarm sounding. Don't hurry, or your long pushes turn into short ones, and you get lost in the menu tree!! Suggested fix: alarm off should be the first item on the top menu. *** Not having a finger in it should be a separate setting*** which I would never turn on. I've left the alarm off so often, because, at 3 in the morning, I didn't remember to turn it back on after a bathroom run. Please fix this. It's terrible!! It will also alarm right away if your battery is low, or if the memory is full. (it will also do a memory full alarm in the middle of the night!!) Unfortunately, the device also does a lot of false alarms, when you first turn it on. The heart rate numbers are not reliable for about the first thirty seconds, and may be way too high or too low. It then gets synced up and it fine, but the alarm goes off until it gets the numbers right. This is also a problem for your data. Last night, I got a 75%! I looked, and it was only the first sample, obviously an error, since the second sample was 95. But now, in the health app, it shows that days minimum as 75. In the health app, you can't tell it was an error. So it gives the wrong impression. So this device does give bad results, some times. I woke last night with the device beeping. It wasn't the alarm, I was sleeping on the button! The button is right on top, with no guard, so it's easy to do! It's a "long press" to see the data while you are recording. A "short press" just gets the word "recording". Not sure what good that is. The battery indicator is pale green on white. Very pale. Pretty much white. Unreadable. If you want to export data, and have an iPhone, the device does record to the apple health app, and there are apps to export from there. Minor Issues: * Weirdly, Bluetooth doesn't work when the device is plugged in. Why!? * There's no way to cancel if you accidentally hit "device data". You just have to wait for it to time out. * When the memory is full, it tells you by failing in the middle of the night. Not at the beginning, when you could clear the memory for more space. You should clear your memory after every download! It also makes the transfer much faster. * Last night, it turned off after 22 minutes, even though it was plugged in. No idea why. * once again, it turned off spontaneously. Not full, no idea why. I woke groggy, so I really wanted o2 numbers, but I'm not getting them from this buggy piece of junk. Pro: * It does allow you to take notes and tag a session. It took me a while to find, it's on the graph screen, click "Remarks". * You can charge this while using it! If you have a long usb cable, it's not a big deal to be plugged in, even while sleeping. * It seems like it would fall off a lot, but that hasn't been my experience, it actually stays on fairly well. I did see one suggestion to just put a sock on your hand, if you have problems with it falling off. Feature Requests: * "merge sessions". I tend to check my o2 levels when I wake during the night. This makes for 2-4 sessions a night. It would be nice to be able to put them back together into one single session. * Have a Pre-alarm, a quieter alarm that lets you know the louder alarm is coming. That way you can roll into a better position, before the alarm blares. This can get you in the habit of sleeping in a good position. After several months of using this, I feel like I have it figured out, and it works for me. But it's always going to be a bit annoying because of bad design. Many hardware companies make terrible software, because they are run by hardware guys. Software matters. I would recommend you not buy their hardware, as the software is terrible.

Just started using this device, after searching for a while, and am so far very impressed. (This was after asking doctors, who were of very little help in recommending any affordable home sleep / apnea monitoring devices... It is sad that doctors don't know, or are just afraid to suggest anything not FDA approved for official medical use. Accuracy and threshold levels of this device might not be hospital accurate -- but they might be -- yet either way, it can help you gauge how you are doing. Just don't consider a medical diagnosis.) It operates stand-alone, but is most useful when you can upload its second-by-second session recordings to your phone or PC. I have used it with the Android app, which is very good, and I plan to use it with the Windows PC software at some point, but that is not so critical, since the Android app is able to share each of its reports and data as needed, so one could send the info anywhere desired (like to email or Google Drive). To answer my own question posted earlier about BlueTooth activity from the device: When it is in recording mode, on finger, it does not appear to use any BlueTooth communication. (The BlueTooth indicator on the display is not shown, and it is not scannable from smartphones.) This is good, because who wants any RF transmissions on your finger while sleeping? And this of course saves battery power on the device and phone, by waiting until you remove it from your finger, before it enables communication and transfer of the recorded data. Good design. The lightness and rechargeable lithium ion battery are much more convenient than having to use insertable batteries. It stayed on my finger all night, not too tight, not too loose. (And for the price, even if the rechargeable batteries do not last forever, I could afford to replace the device after some years.) If I have any significant issues going forward , I plan to update this review.
