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.

REVIEW OF THE EMAY SleepO2 SpO2 AND HR MONITORI recently purchased an Emay SleepO2 Pulse Oximeter. The unit has been flawless in its performance. Here are my observations in detail:IN THE BOXThe system is shipped in a small plastic box that appears to be intended for long term use to store the sensor and its associated data processing unit. In the box is a silicone rubber sensor unit that fits over a finger and gently but firmly holds the sensor in place. It has a short, flexible cable attached which is terminated with a male micro USB connector. Also in the box is a wristwatch-like data processing unit with a silicone rubber wristband that appears to be large enough to fit most anyone. The data processing unit itself is approximately 16 x 45 mm and 12 mm deep. At one end is the micro USB connector that mates to the sensor assembly, and is also used to charge the internal lithium battery. This port has a cover that, when closed, looks like a small wire attached to the body of the unit. A quick tug on the wire-like part exposes the USB port. On the face of the unit is a single button that is used to turn the system on. There is also a tiny multicolored LED that gives an indication of the system status. There is a short USB cable for charging the battery, but no charger. Finally there is a users manual which appears to have been written by an english speaking author - A real plus!FIRST USEFollowing the instructions in the user manual, I first charged the battery. The manual says that battery charging can take up to 3 hours however my initial charging time was closer to 1 hour. While the battery was charging I downloaded the app from Google play and installed it on my Android phone. When the battery was charged I preformed the initial synchronization as described in the manual. This sets the date and time, and clears the system's memory. Everything went exactly as it should. No problems here!At bedtime I placed the sensor unit on my middle finger and strapped the data processing unit on my wrist. I had a bit of trouble plugging the connecting cable in as it was a snug fit. It has since loosened up some. I started the system by pressing and holding the button until the LED lit green and began to blink, then it was off to bed.In the morning I took the sensor off my finger and pressed the button on the data processing unit to turn it off. If you don't turn it off it will turn off automatically after 3 minutes. After I had breakfast I unplugged the sensor from the data processing unit, Opened the app on my phone, and pressed the button on the data processing unit to turn it on. Next I clicked on the App screen where it says "Connect to my device". The app connected to the unit and downloaded the data from the night before. I set the data processing unit aside (It turns off automatically). Now I looked at the data, created a PDF file and emailed the PDF file to myself so that I could print it and store it on my main Windows machine. It was simple, and everything went exactly as expected! I also downloaded the CSV file and opened it with EXCEL so that I could examine it in more detail.ADDITIONAL INFOI have now used the EMAY SleepO2 for a week, and there have been no issues at all. Everything works exactly as expected. The sensor unit is comfortable to wear, it does not pinch in any way. The USB cable has loosened up some but is still snug and secure. Charging continues to take just over an hour so I expect that the stated battery life of 12 hours may be conservative. The app is easy to use, not complex or hard to understand. My only issue was that I thought that the flashing green light was a bit too bright, so I used a tiny piece of neutral density film https://www.amazon.com/gp/product/B08CRMYMB1/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1stuck over the LED to dim it. You certainly can't see the light when you are asleep, or when your hands are under the pillow or the covers, so this is really nit picking.While I cannot speak to the accuracy of the SleepO2, I do use a Samsung Galaxy Watch4 Classic which has the ability to record SpO2 readings overnight, and the two readings are essentially identical as far as I can tell, although the watch data is not at all easy to export.There are other, clip-on units, which can deliver similar performance to the SleepO2, but the cost of non-reusable batteries, both the direct cost and the impact on the environment, as well as the cost of self adherent tape needed to keep the clip-on units in place, make the long term use of these units more expensive than the SleepO2.This is a fine piece of equipment and was well worth my money. If you need this sort of device this is the way to go! Five stars.

The Sleep02 works great. H I have found the unit to be very accurate; I have compared the readings with my visiting nurse's unit and found it to be perfectly accurate. I love that the reports can be downloaded to excel or printed in summary for my doctor. All is great with the unit, I find that it is comfortable and stays in place at night. The fact that the company took time to reach out to see if all was well with the unit and software shows how committed and caring they are, a rarity these days. Happy to have ordered from this company.
