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. Review: Impressive pulse oximeter with overnight storage of pulse rate and SpO2 level taken every second - 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. ## Features - With a memory of up to 40 hours the EMAY Bluetooth Oxygen Monitor allows you to record continuous blood oxygen & heart rate during sleep or other occasions. - Free iOS/Android app for reviewing your historical data (second by second), and providing professional blood oxygen & heart rate trend reports to share with others. - Record First, Upload Later!

I have uploaded the data to my phone already.** A: Once downloaded there is a "dustbin" symbol in the top right of your phone screen to delete the data from the Oximeter **Q: Can results be put on laptop? I have no mobile phone. Also can it be used as a one off for quick oxygen test?** A: No, as per the information in the description, it's only compatible with Android or iPhone. As for a "quick oxygen test" why would you do that? You would want a fair bit of data over time to average out the readings, because your SPO2 does fluctuate. A quick reading might give unnecessary concern, if it's dipped to say 92% briefly but gone back up to say 98% - this info was relayed to me by NHS 111. You can just as easily buy a cheap oximeter and get the readings from the actual device then write them down. Always work with your healthcare professional. Hope this helps. **Q: How well does this attach to your finger during sleep?** A: It has rubber inside and fits and stays on finger during sleep. It stays very well and doesn't hurt. **Q: Only getting 6 hours recording on one set of batteries, 8 hours on another set. Says 24 hr Continuous recording? I must have a faulty unit.** A: I managed to get three 8 hour recordings from one set of batteries. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Can't honestly fault this *by M***. on 24 February 2026* I was getting weird readings on my Apple Watch of low SP02 at times during the night.

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. ## Frequently Bought Together - EMAY Sleep Oxygen Monitor with Built-in Recording Capability | Track Continuous Blood Oxygen Levels & Pulse Rate Overnight | Provides Sleep Report & Raw Data - KardiaMobile 6-Lead Personal EKG Monitor – Six Views of The Heart – Detects AFib and Irregular Arrhythmias – Instant Results in 30 Seconds – Works with Most Smartphones - FSA/HSA Eligible --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/752837620-emay-sleep-pulse-oximeter-with-built-in-recording-capability-record](https://www.desertcart.pl/products/752837620-emay-sleep-pulse-oximeter-with-built-in-recording-capability-record) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-25*
