EMO-90

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. :)

Arrived promptly and I began the start up. The instructions were easy to follow. I’m older and not tech savvy, but was able to hook up to my iPad Bluetooth. The oximeter easily stays on my finger overnight. I did not want to tape around my finger so I used a soft ankle sock over my hand for overnight recording to insure the monitor did not slide off. In the mornings I simply turn on my oximeter and open my iPad. I click on my downloaded EMAY App. The App screen is easy to understand and prominently gives the option to Edit or Connect. The graphs are very easy to understand. There is even a place to make remarks on recorded readings of the SaO2 and pulse rate. The recording is continuous minute by minute. This monitor gives a great picture of what happens with SaO2 and Pulse rate anytime of the day, but especially overnight. Plus, no batteries are needed. Simply plug in to recharge. I am very pleased with my purchase. In addition EMAY customer service reached out to me to insure everything was working as expected and to ask if I had any problems.

I have a garmin vivosport watch, another pulse oximeter that I got off of Amazon and then this emay unit. The Emay is significantly better than the other devices for my uses which are mainly tracking heart rate and blood oxygen. The Emay gives the most consistent results and records all data up to 72 hours. The graphs created by the phone app are very informative and it is easy to access heart rate and blood oxygen values. The app prepares an excellent summary which can be sent to your doctor. Battery life is good as well. It is simple to delete data sets, turn recording on and off, and synch the unit to the app.

It is important for my health to monitor my heart rate, and have a constant record of my pulse values, and values of my oxygen saturation. And the values have to be accurate. First, I tested them against other brands and found that the other brands fell short of accuracy and consistency. The other brands were also difficult to read. The EMO 90 has an easy to read, friendly display! Then I tested the EMO 90 against the hospital blood pressure sphygmomanometer and pulse oximeter, and repeatedly had exact, matching values for pulse and oxygenation. That was impressive! To be in sync with a $5000 piece of medical equipment is good enough for me! Looking at my finger gives me a spot check. It lets me know my oxygenation and pulse at any moment. And the display is set so I may look at my finger from just about any angle or show it to my physical therapist, again from almost any angle. No arm contortions needed for a device read. What the EMO 90 gives me is a second by second recording of my pulse and oxygen saturation on my smart phone. I know exactly at what time my oxygen dips down and when my heart rate is too high or in the lower range. I may require medicine intervention as an intervention. I can copy that information and email it to my cardiologist and pulmonologist. The battery lasts for days and is USB rechargeable. I plug it in, unplug, and I am good to go for hours of pulse and oxygenation recording. I never worry about it losing battery power. This is a very feature rich device. And from little questions to big questions the tech support staff is friendly and welcoming. If they don’t have an immediate answer, they escalate and give me a time range of when someone will reach back to me. They answered some of my questions on a weekend. I didn’t expect to hear anything until Monday. This is THE pulse oximeter I am going to recommend to my family and friends that need to keep accurate records of what’s going on with them. There is an easy to connect lanyard, and a rubber friction device to hold it on my finger overnight without it slipping off. I wake up with the EMO 90 just where I left it recording every second of my pulse and oxygen saturation. Pairing the EMO 90 to my phone was a cinch and I can’t think of a better device. I don’t want a different device. The EMO 90 is IT! If the company comes up with a more feature rich device then the EMO 90, I would consider it, but I wouldn’t trade for another company’s offering. The EMO 90 is mine! Special thanks to your telephone support folks, their escalation links, and the engineers that came up with such a user-friendly comfortable product. I am an EMO 90 Fan!

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.

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.

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.

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.
