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.

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.

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.

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.

This amazing little device may just end up saving your life! I had long suspected disturbed sleep and compromised blood oxygen levels, and this Oximeter validated those concerns. It stayed on my finger throughout the night and gave a comprehensive, detailed analysis and a medical looking report in PDF format (via the App, which was super easy to set-up). I have since sent these reports to my physician for investigation and follow-up. I highly recommend this device!

I am happy to report that the Oximeter is working extremely well. I elected for your product specifically because it can record readings continuously rather than most meters which only show a measurement at a specific moment in time. I should explain that I suffer from Obstructive Sleep Apnoea and use a CPAP machine overnight. I had suspected for some time that once I was asleep my breathing became very shallow and thus my O2 stats dropped and the fact that I could record this and more download it and send it to my consultant has been most helpful. I am waiting for my next appointment at Leicester when we can discuss the findings and plan accordingly. The only slight issue I have encountered is that sometimes during sleep the normal movement of your hands can cause the meter to move just enough so that it thinks you have taken it off and the readings stop, possibly an on/off switch that you need to actually switch off rather than an "auto off" would solve this but it is a minor issue.

The device worked as expected for the first few nights. We now have a problem that when first placed on my finger the readings take 3 to 4 minutes to display any readings which are very low and setting off the alarm. It takes another few minutes to display the correct oxygen level. It appears to indicate correct readings for the rest of the night. I have queried this with the manufacturer and waiting a reply. I may have to return the equipment as being faulty which is a pity because the device does exactly what I wanted it to do.

We bought this Oximeter to replace an earlier type and to have better information on our oxygen and pulse levels. Monitoring oxygen levels is a relatively recent indicator but has proved to be essential in managing lung related problems and deciding when medical intervention is needed. The EMAY Oximeter is excellent especially as the associated App is easy to use and provides a clear record of readings and history.
