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

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.

I have been using this Pulse Oximeter Recorder for a week to monitor my sleep apnea. It is easy to use and generates very detailed reports after every night which you can download as a PDF or an image file. You can also download the raw data to import into Excel if you like to do your own analysis. The 48 hour data limit is not a problem if you download the data every day, since it clears the device memory once you download the data. I charge mine every morning when I get up after I download the data, so the device is ready to go the next night. Battery life is not an issue since I charge it daily. The finger cuff is comfortable to wear, although the little velcro strap to hold the device/wire against your finger is marginal. I use a small strip of self adhesive medical tape to secure it better. Before I started using the tape, I did have the device come off my finger while I was sleeping a few times, but the device started recording again once I woke up and put the cuff back on my finger. The data collection just shows a blank during that time. The device syncs its time to your phone via the app. The app (Android for me) is easy to navigate and works well to access reports and status. This is the only recording pulse oximeter I have used, so I cannot compare to other brands or devices. But this one meets my needs beautifully.

This product works well. It is easy to use and the reports produce using the app. Are east to read and useful. Only reason it gets 4 stars instead of 5 is because the sensor will come off your finger while your sleeping sometimes.

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.

Excellent price point. The device does what it says it does and is easy to use. It generates detailed reports which display heart rate and blood oxygenation over time. I recommend it.

delivery was fast. product as description. its packed in a cubic plastic box. handy to use&store. battery charge is fast. roughly can use for 2nights for 1 charge. connection with phone is good by Bluetooth. data can store in the watch & disconnect the phone while using. save phone battery & no blue light during sleeping. report can be shown to doctor as reference. the finger cap is spacious. good for thick fingers. but mine is narrow. i find its loose& would fall off. i needa fix a bit by something add on. its also written in users instructions. the battery indicator shows only when its in live mode & connect to phone. the band doesn't contain screen. overall, its effective gadget if u wanna have reference of ur oxygen levels & heart rate.

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 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.
