I previously had a much older brand and model of recording pulse oximeter that was a hassle to use, is now discontinued, and I was unable to get it working again. I needed a recording model to confirm and subsequently monitor my sleep apnea (including while using CPAP), so I went online and discovered the Emay Sleep02 model. I ordered one and was very pleased and pleasantly surprised to get and start using it quickly with no problems -- right out of the box with no hassle! To test accuracy I ran it on one finger while wearing one of those little plastic standard pulse oximeters (clips on the finger tip like at the hospital, clinic, or for home) on the neighboring finger. The results were the same or within a percent on both! I've now been using it over several nights (plus also running tests during the day and normal activities, including during exercise!). My wife also started using it (it can be used by multiple users and keeps track of everyone's data separately). It's wonderful and simple to use. You can do spot checks on the phone app while it's recording but don't have to otherwise stay connected to the phone and app. You can check recorded details on the app after recording, save raw data, and get a one-page pdf summary report with tables and graphs of the results, which you can review, file and save digitally or printed copies, and/or send to your doctor or others you might want to share it with, while at the same time keeping it private and secure. It's also light weight and not cumbersome, as well as not expensive. You just have to be careful not to snag the wire that runs between the wrist unit and finger device. I've had no problems with it falling off. I recommend it most highly! Review: Accurate Device and Comfortable to Wear - 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. ## Features - Most lightweighted wrist pulse oximeter in the market, it weighs only 100 gram that one can sleep with comfortably.

Has anyone had this issue?** A: Yes I have noticed this problem-Pulse Oximeter stopping in the middle of the night, usually after 2 hours & am unable to provide an explanation.

Only SpO2 and pulse. There is nothing in the manual or App settings for motion detection/monitoring that I can see. **Q: can I view the report on a windows computer?** A: The app has an option to export to PDF or image. The PDF report can then be viewed in Windows. There is also the option to export the raw data to CSV file. ## Customer Reviews ### ⭐⭐⭐⭐⭐ An excellent recording pulse oximeter *by J***G on March 19, 2026* The Emay SleepO2 recording pulse oximeter is excellent, accurate, very user friendly, and ships fast!

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.

Glad I made the purchase. ### ⭐⭐⭐⭐⭐ The Emay Sleep O2 Pulse Oximeter is a excellent device and is great for CPAP device users needs. *by S***X on June 4, 2022* 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. ## Frequently Bought Together - SleepO2 Wrist Recording Pulse Oximeter by EMAY | Continuous Pulse Oximeter to Record Blood Oxygen Saturation and Pulse Rate Overnight | Export Sleep Report & Raw Data - KardiaMobile 6-Lead Personal EKG Monitor – Six Views of The Heart – Detects AFib and Irregular Arrhythmias – Instant Results in 30 Seconds – Works with Most Smartphones - FSA/HSA Eligible - Innovo FSA/HSA Eligible iP900BP-B Fingertip Pulse Oximeter, Blood Oxygen Monitor with Free App, Plethysmograph, and Perfusion Index (with Bluetooth) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.uy/products/372462390-sleepo2](https://www.desertcart.uy/products/372462390-sleepo2) --- *Product available on Desertcart Uruguay* *Store origin: UY* *Last updated: 2026-05-01*
