SleepO2 Wrist Recording Pulse Oximeter by EMAY | Continuous Pulse Oximeter to Record Blood Oxygen Saturation and Pulse Rate Overnight | Export Sleep Report & Raw Data

This is a well made simple to use pulse / oxygen recorder if your needing to do overnight checks on these health areas , I used it to check if I have sleep apnia issues and I’m pleased to be able to self test for this , the 8 hour download to the app for reviewing minute by minute is excellent health history to keep if you need to show a doctor in the future , highly recommend this product

What a great product I have purchased two cheaper different brands in the past year and both failed . I am so pleased with the performance, quality, and it is so easy to use. The accuracy of the oximeter is excellent and easy to print out and store the data. I have COPD and my respiratory nurse was extremely impressed with the results and accuracy of it . I can honestly say that I would recommend this Oximeter . Phil in Somerset

Bought for my wife to monitor oxygen levels during sleep. She has been diagnosed with sleep apnea and the cpap doesn't monitor oxygen levels. The app is great and gives lots of information and printable reports. It does come with a tiny velcro finger strap to keep the finger monitor in place but 5mm micropore works better. Had a query about something on the app and emailed customer services and got a reply back quickly. I was a bit apprehensive as its cheaper than lot of the overnight monitors but really pleased and reading's appear to be accurate as have compared with a medical one.

Having got OSA and use a CPAP machine I like to check, periodiacally, how well my treatment works. I have tried to use a simple finger tester, which is OK for an instant reading. But, I wanted to do over night tests. I have used a professional tester from the hospital, but understand they were very expensive. Consequently, I was delighted to find this EMAY recording pulse oximeter, which is easy to use, comfortable and didn't cost a fortune. this Pulse Oximeter is great for over-night use.

I bought this for my partner for Christmas as he suffers with sleep apnea and has terrible sleep. It was well worth the money! Thanks to this watch he's been able to see when his body has low oxygen levels and see how this effects his heart rate. He can tell when he's had a bad nights sleep and how it impacts his day. He likes the daily report and overall it's helped him understand his sleep much better. He's under health physicians already to help diagnose the cause of the sleep apnea. But I believe this watch has helped him become more mindful of his daily lifestyle habits and what he needs to change. Overall a great bit of equipment, and good customer service.

This product has some fundamental flaws which is unfortunate. The main flaw is the weak cable connecting the finger sensor to the wrist band. As this is intended to be used during sleep, that lose cable has the chance of being snagged and ripping out. Which it did on day 5 of use. The finger sensor is attached to the finger via a very thing fabric wrap with a velcro patch. However, this isn't "sticky" enough, so every morning I found that the sensor had come off the finger as fabric strip had come off. The app is ok, but the has some flaws. You can't download data whilst the sensor is on the finger. And every sync is a new file, rather than added to the current day's results. This is cumbersome. Also, I found gaps in the recordings and some results which seemed to indicate my heart had stopped which I am fairly sure was not the case. The battery charges very slowly, could do with being USB-C to allow a more rapid charge (takes hours). Most importantly for those monitoring for O2 saturation, the SleepO2 does not provide direct alerts for low O2. When you set those thresholds its just for data viewing purposes.

This sleep 02 wrist oxygen monitor is an excellent way to track oxygen levels and pulse rate during sleep and not expensive. The app is super easy to install and provides data which is simple to understand. Being able to assess sleep health has proved very beneficial. I bought it to assess my breathing as hadn’t worn my CPAP mask for 2 weeks and wondered what effect this had on my oxygen levels. Well I soon found out that things weren’t great - large oxygen dips and varying pulse levels. Each night I’d try something different (pillows/breathe easy strips/no alcohol) in the hope that if I could reduce my sleep apnea incidents I’d not need my CPAP mask anymore. Wishful thinking! BUT this amazing 02 wrist monitor has allowed me to to understand just how much I need my mask and not dislike it so much! Worth every penny, best purchase I’ve made in a long time.

I need the device for overnight recording and, having owned other recording oxymeters, I find that this one works reliably, with a stable signal, and the sensor is reasonably comfortable and does not easily come off. The battery reliably lasts overnight. There are no signal drop-outs, and the measurements appear accurate. The phone app can export data, and the output format is compatible with OSCAR. It is important to note that this is a designed for overnight recording. Even though nominally it can be used for spot measurements, this is not its primary purpose, and therefore spot measurements require some fiddling with apps and settings. In all, a single-purpose device, that does what it is designed for, and does it well at a cost sensible for a home user. It does not replace a spot oxymeter however, so, for spot measurements, I use another device. My only (very minor) gripe is that there is no alarm if the saturation drops. Again, this is not the intended use, but it would be a very easy function to add to the app, so I would be very happy to see it in the future. For the moment, I keep using it for overnight recording.

I'm impressed by this device with the ease of downloading the app and using the app. It is simple to use. It is very similar to the ones used by in professional sleep studies. My doctor was impressed with the report and summary. I use it to see how I am doing with my APAP at night. My wife is on oxygen at night and checks how her levels are doing. It will work good for travel to check at different elevations. This is a great Pulse Oximeter for the money. Glad I made the purchase.

I received my Sleep O2 Pulse Oximeter a few days ago. It arrived in a special plastic cube that insured no damage during shipping. The instructions included were accurate and concise to get you up and running in a very short time. It is best to charge the oximeter before using, and it came to a full charge in a very short time. In the past I have used a Emay EMO-80 Pulse Oximeter and it used the same app as the new Sleep O2 does. It would be wise if you have also used a EMO-80 device and either had the app installed on your phone for it and deleted it, or have the app on your phone presently, to be aware that your old data from the EMO-80 will be presented to you when syncing the app and phone for the first time. When I installed the Sleep O2 app to my Android phone it apparently recognized the old data and attached it to the newly downloaded app. At that time I was trying to sync my phone with the newly installed app for the first time, which is supposed to set date and time from your phone, and set the app to use this method of date and time tracking going forward. Because data was carried forward it affected the syncing of date and time with incorrect results. I corrected this on my second download from my second nights use of the Sleep O2 device, but first I deleted all the old data from the Sleep 2 app on my phone. I am a CPAP user with obstructive sleep apnea with hypoxia. I have been through a sleep center test and diagnoses. The equipment a sleep center uses is very comber son and does not encourage a good nights sleep while testing. I have been using a Resmed cpap machine and their app to generate a very good report to take with me when visiting my primary and pulmonary doctors. Now I will also be able to take with me, to my doctors a very good oximeter report thanks to Emay. The Sleep O2 is very easy to use and is so light that it should not hinder your sleep. I will use it as reports are needed. The downloading of data to your phone is a simple process and the display will let you know after a very few seconds that the download has completed. The SleepO2 is a excellent choice for tracking O2 and pulse over longer periods of time and Emay support is the best. I have found only two minor things that might improve the user experience. 1. The tiny power button on the face of the wrist unit is black in color and is the same color as the face of the screen that it is in the center of. It can be difficult to see in low light or with out your eye glasses on. 2. The USB cable that is plugged into the wrist device has a extended male end plug that is longer than other similar USB cables, and could be considered proprietary. I tried another cable I had and the metal male plug was not long enough to make contact inside the wrist unit socket. Over all a great choice at a fair price.

This is my second overnight oximetry unit and it is very easy to use, seems to be very accurate compared to another oximetry unit, and results in a very nice .pdf report satisfactory to share with my pulmonologist. The price of this unit is less than half of my first similar unit.

This is an excellent SPO2 sensor. The reports are surprisingly thorough and well done. The cup that holds the sensor to your finger is much more comfortable than rigid units that clamp onto the end, especially if you plan to sleep with it. The small velcro strap to hold it on is a nice extra feature. There are a couple of things I would change. I realize they'd add cost but I think it would increase the value correspondingly. First, add a display that can be activated by a side button. It feels like a watch and I catch myself looking at it for the time. Second, add a way to dim the green LED. It is very bright once the lights go out, although once you get used to it, it makes a nice "flash light" so I don't have to turn on a light to find my way to the bathroom in the dark. Third, add a vibrator or audible alarm that alerts the wearer or others in the room that the oxygen level has fallen below a set limit. And last, replace the cup with a smaller sensor housing that can be held on with velcro. While the rubber cup is much more comfortable than clamping SPO2 units, 7-8 hours of constant minimal pressure can be uncomfortable in the morning. Overall I give it 4.5 stars out of 5

Easy to use, great information. I wanted to get this as my doctor told me that maybe sleeping on my side would be enough to not have to have a CPAP or other corrective measure for moderate sleep apnea. So I wanted to experiment with sleeping on my side and see how I did. I used this several nights and downloaded the data onto the app, printed out the reports, and the reports confirmed my apnea and showed that sleeping on my side did not make much difference! So at least now I know and I have done my homework. The reports also alerted my doctor that my O2 levels really drop at night and I may need supplemental O2. My husband has used this monitor also and it also has merely confirmed the results of his home sleep study. Now I will be loaning this out to friends who are curious about their overnight O2 levels. And I will be doing an overnight sleep titration study as my doctor wants. Thanks for a great little product.
