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 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.

Great Product, easy to use and set up. I wanted to monitor my pulse and O2 levels while sleeping, the unit collected good data that was easy to download and analyze. The unit was comfortable to wear, reasonably priced and certainly better than having to do a “sleep study”.

I was really excited about using this oximeter. The velcro strap that wraps around the finger to secure the finger sensor doesn't work well. I recommend replace it with something more secure and durable. I initially was very impressed with this oximeter. The results are pretty consistent, and I tested it with taking Magnesium which made my sleep apnea worse as expected. I tried sleeping with no pillows, with 1 pillow and with 2 pillow, on the side, back, etc... and the results seemed to be pretty accurate. Then I did a Home Sleep Study and wore this Oximeter at the same time. When I got the results, they appeared to be close, but when I matched the X-Axis data from both tests, I noticed that they were off. What appeared at the EMAY approx 2 hr mark is similar to the Sleep Study 1.5 hr mark, and the larger drop of oxygen at the EMAY 3.3 hr mark is similar to the Sleep Study 2 hr mark. Similar for the rest of the hours up to ~6th hour. The Y-Axis data seemed to be accurate in terms of how low my oxygen level drop - compared to the highlighted dipped in both studies - 88% and 86%. It seemed to me that the EMAY results lag the Sleep Study result and with variations. As for the Pulse Rate, there are some very different result where the Sleep Study picked up a spike that the EMAY didn't. Assuming the Sleep Study is more accurate --- Overall, this Oximeter is good for home use, and it's best to compare day to day results from the Oximeter for consistency, and to determine your general sleep apnea condition, but I wouldn't rely on the time of occurrences or any specific details at certain time of the night. I will continue to use the EMAY results to measure whether my sleep apnea is improving, stable or getting worse, and what changes I make work and don't work. What I do look at in the EMAY results is the high level glance to see how frequent I drop below 95 in oxygen level, and how frequent my heart beat spikes or drops.
