EMAY Sleep Oxygen Monitor with Built-in Recording Capability | Track Continuous Blood Oxygen Levels & Pulse Rate Overnight | Provides Sleep Report & Raw Data

Did a lot of research and bought this device. It works great. There are several pluses: Easy to use. Finger strap is great and prevents the device from accidentally falling off The reports are in depth and I share these with my doctors I feel this is medical quality and the company actually follows up. What great service.

What other reviewers said is true - it fits tight, and is definitely annoying when you go to bed. I felt like my pinkie was in a clamshell and the clam didn't want to let go. Very uncomfortable. BUT, read on... About the Retrofit: Looking for a solution, I rolled up two very small bandaids into little "bandaid cigars" and inserted one on each side of my inserted finger (alongside my finger) which provided a slight (very slight) "opening" of the clamshell to support my finger. When I did this, it worked well for comfort, I did not feel like my finger was squeezed an a clamshell all night long, and the device still recorded my data even with the retrofit keeping it just a tiny bit less tight. The key here is to insert a little extra padding on the white edge where the "clam" closes -- vs. a lot of bulk -- just a hint of extra padding so your finger isn't squeezed so tightly. If you opt to ry this, just make sure it's still recording data (look for the blinking light). If it's not, you've payed it open too far and it's not picking up a reading. About Keeping it on all night: It fell off once during each of the 2 nights I used it (I reconnected it when I woke during the night - then it continued recording data). So far I have not used the velcro strap designed to help keep it on - haven't found that necessary - I don't move that much during sleep. Finger choice: My physician friends told me any finger works for reading your data, so the choice is yours. I put it on my left pinkie since I'm right-handed and it's convenient to have a hand free during the night. Connecting & Reporting to the App: Setting up the app was super easy. Not entirely sure how to make sense of the report it spits out into the App, but the data looks clean and the graphics are pretty simple, so I'm sure I'll figure that out. Batteries: It's an energy eater - you need to replace the batteries (2 AAA) every 3 nights or so. I use rechargeable, so it's no biggie. Rechargeable batteries and chargers have come down a lot in price the past decade or so, so it's the way to go. Rechargeable batteries require special recycling, so don't throw them in the regular trash give them to your local recycling center. So far, happy with the purchase. It's nice to have a pulse ox that records data.

For months I was waking up with massive migraines, feelings like I hadn't slept in weeks, fatigued and brain fog constantly. I'd talked with my doctor about setting up a sleep study but they were backlogged. Every day I felt progressively worse and worse. Then I though "I'll just do my own sleep study, see if I really do have apnea going on". I ordered this device and was absolutely shocked at what I saw. I knew it wasn't good, but not this scary! I was dipping clear down to 68% oxygen saturation (65% is where your lips and fingers turn blue). I showed my Mom this first graph and she just happened to have an extra CPAP machine stored away. She got me setup and the first night was incredible! I felt like a new human! (2nd graph). This all went down 2 months before my actual sleep study which confirmed, yep, I have a pretty good case of sleep apnea. I feel like without this tool, I genuinely wouldn't have survived! As for the device itself, it works pretty flawlessly! It's comfortable, stays on well through the night and uploads the data to the app with ease. Part of my nightly routine now! Only thing that's kind of a bummer is how quick it runs through AAA batteries (a set every 8 days or so). I picked up some rechargeable batteries, which I'd highly recommend. Beyond that, solid device, well worth the price! If you suspect sleep apnea (you snore, you wake up fatigued, you have brain fog, mornings are way more rough than they used to), BUY THIS!

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

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.

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!

Didn’t have any issues setting it up. Has a good polling rate and helped figuring out a health issue im currently getting diagnosed.

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.
