EMAYSleep Oxygen Monitor with PC Software & App | Bluetooth Pulse Oximeter Rechargeable for Overnight & Continuous SpO2 Tracking with 72 Hours Built-in Memory | Gives Informative Report & Analysis

I have had a problem with "tiredness" the last few months. My doctor recommended an "oximeter" to check my oxygen level from time to time and preferable overnight! I shopped around and found this unit at a reasonable price. I have had and used it now for about 3 weeks and find it accurate and VERY informative. It has revealed that on several occasions my oxygen levels dropped very low. They should not drop below 90 and mine were dipping below that. It is described as a "dangerous" situation. One is flirting with oxygen starvation and the resultant problems with heart, brain etc. I already have heart issues so this was very good information. The unit is easy to program and to set the alarm as you see fit. I have mine set to go off if it drops below 80. It is "rechargeable" and seems to have a good battery life for something very small. It has an "annoying" alarm which is what you want to wake you to get you breathing heavier.The only down side and it's not worth taking a star it one of those "me" things. I worry about it slipping off my finger at night. I have acquired some of that "stretchy" tape and it helps secure it to my finger. You can use any finger you want or that will fit into the device. I have suggested to the company they create some sort of "holder" to help keep it steady. It has never slipped off my finger, but it's one of those nagging worries. I will continue to use it till I am told to stop, but will still keep it around for "spot checks" of my oxygen level. I am scheduled for a "sleep study" to see what can be done about this oxygen problem. I should note...I am over 80 years old!So, bottom line, if you are tired all the time...snore loudly or awake suddenly and frantically...might look into this little guy.

Just started using this device, after searching for a while, and am so far very impressed.(This was after asking doctors, who were of very little help in recommending any affordable home sleep / apnea monitoring devices... It is sad that doctors don't know, or are just afraid to suggest anything not FDA approved for official medical use. Accuracy and threshold levels of this device might not be hospital accurate -- but they might be -- yet either way, it can help you gauge how you are doing. Just don't consider a medical diagnosis.)It operates stand-alone, but is most useful when you can upload its second-by-second session recordings to your phone or PC. I have used it with the Android app, which is very good, and I plan to use it with the Windows PC software at some point, but that is not so critical, since the Android app is able to share each of its reports and data as needed, so one could send the info anywhere desired (like to email or Google Drive).To answer my own question posted earlier about BlueTooth activity from the device:When it is in recording mode, on finger, it does not appear to use any BlueTooth communication. (The BlueTooth indicator on the display is not shown, and it is not scannable from smartphones.) This is good, because who wants any RF transmissions on your finger while sleeping? And this of course saves battery power on the device and phone, by waiting until you remove it from your finger, before it enables communication and transfer of the recorded data. Good design.The lightness and rechargeable lithium ion battery are much more convenient than having to use insertable batteries. It stayed on my finger all night, not too tight, not too loose. (And for the price, even if the rechargeable batteries do not last forever, I could afford to replace the device after some years.)If I have any significant issues going forward , I plan to update this review.

This oxygen monitor is a top choice for professional use. I rely on it for patient monitoring, and the audible alarm is a game-changer—you can set it to trigger at your preferred SpO2 level, ensuring you’re immediately alerted. The alarm is clear, even through a baby monitor, and the battery consistently lasts around 12 hours, perfect for long shifts. I was so impressed that I bought a second unit for 24/7 monitoring.One of the most convenient features is its simplicity—no app or Bluetooth required, which is a huge improvement over the wrist version I previously used. With no need for constant checking or toggling settings, it frees up time for other tasks, almost like having an extra set of hands. Navigating the settings is intuitive, and the company’s proactive customer support shows a genuine commitment to quality.One minor downside is that, with extended use, it can leave a red mark, so I occasionally switch fingers to prevent pressure marks, especially for overnight monitoring. While the reports are detailed and professional, I’ve moved away from using them as this device’s real-time tracking has become my go-to. Overall, the audible alarm, battery life, and ease of use make this monitor an invaluable tool for reliable, hands-free patient care.
