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.

I am very happy with this oximeter. I have another one, but it does not have the features this one does to collect data as you sleep. I was specifically instructed by my consultant to take night-time readings. The oximeter works very well and stays on securely during the night. The data collected is thorough and easy to collect and read via the app. It can generate detailed reports. Given its functionality, I think the price is very reasonable. All in all, I am very pleased with this purchase and would recommend.

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.

Great little oximeter, actually stays on my finger throughout the night which i thought may be impossible as im a fidgeter and dont sleep very well. Heart rate and oxygen reading also match up with my smartwatch so i guess thats a good thing Easy to set up and no problems thus far! Also like that it downloads my readings on to an app which i can also save to my phone and make notes on making easier for me to show my dr and consultants. Came with batteries too!

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

I purchased this device just over a month ago & have been very happy with the product & the associated Emay App, which allows me to view & save my data. The finger strap is a must, to consistently keep the device in place overnight (it still can occasionally come off over a restless night). Additional useful information for anyone not familiar with an oximeter, with a recording facility, would be that in recording mode, it uses lots of battery energy & batteries will only last 2 nights. The device is not compatible with rechargeable batteries so factor in frequent battery purchases! ( Apparently one can contact Emay for a discount code to purchase batteries, presumably from Amazon but I haven't received a code yet, so cannot comment on whether this makes it cheaper than buying them locally). It is a small gadget & the writing on the mode selection screen is very small (reading glasses or magnifying glass required!). In summary, a good, budget friendly purchase ; it does the job & I am very satisfied with it!

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.

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

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

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!

I purchased this pulse oximeter for sleep study. It was a great device and served my purpose adequately. I will buy it again if required.

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!

Works really well, with the little strap it stays in my finger all night. The PDF report from the app had good summary including the SpO2 graph and pulse Data can be exported with a second granularity as CSV and spo2 files for thos who wants to analyze the raw data. It will store the data in the sensor so no need to keep it synced with th phone, that is done in the morning when you wake up.
