Wellue O2ring Pulse Oximeter - Rechargeable Bluetooth Oxygen Saturation Monitor with Reminder| Wearable O2 Meter Continuous Tracking of Oxygen Level and Pulse Rate with Free APP & PC Software

In 2021 my husband was hospitalized with Covid. He was in the ICU for 3 months. During this time he had several lung related issues that resulted in severe scarring of the lungs that affects his oxygen levels. When we brought him home from the hospital I needed a way to see where his oxygen was at through the day and night. A ring that would sound alarms if his oxygen dropped below a healthy level. I spent hours researching all the different rings on the market and decided to give the Wellbu ring a try.When the ring came we put it on one finger and a pulse ox on another finger and they were within a point from each other or the same. As we would do his physical therapy it was crucial to know when his oxygen would drop below a healthy range. So we put the ring on his finger and this alerted us while he was doing his walks or physical therapy that his oxygen had dropped below the level we had set and he would sit down and allow it to come back up again.One of the things we loved about the ring is that it’s one of the few rings that tracks his oxygen continuously from the time he put it on until the time he took it off. Then it saves his oxygen levels in the ViHealth app from every time he wore the ring that we were then able to take to the pulmonologist and use this to help us make important decisions relating to his improvements.The other great thing about the app is when his oxygen dropped we could zoom in and track the time period from when it started to drop and how long it was low for. You can zoom in and get a close up view of exactly where his oxygen dropped to, it puts a triangle on the graph of where the alarm sounded. You can drag a line across the app and it tells you exactly how low his oxygen got to and when the alarms sounded. You are able to choose in the app at what point you want the alarms to go off with the heart rate and oxygen. When the alarm goes off on your phone of which you can also set a sound level for the alarm in the app. But the ring also vibrates when it hits the warning levels you set for it. This was convenient in the night because when his oxygen dropped he would be woken by the vibration and a lot of times his oxygen dropped because it came off in the night so he was able to put it back on without me having to do anything. Of course I knew it was low because of the alarms but a few times I was so tired that I slept through it (because I had it set low, needless to say I turned up the alarm the next night) but he was able to wake up because of the vibration and put the oxygen back on.It also gives you a heart rate reading and motion reading as well this was extremely helpful during the night to know if his oxygen dropped because he got up in the night.From the time I brought my husband home from the hospital my biggest worry was how would I know if his oxygen dropped to dangerous levels again without always having to be watching a pulse ox on his finger. This helped me be able to sleep knowing that if it dropped I’d be alerted. I was able to walk next to him and push his wheelchair next to him as he walked and know exactly when his oxygen got too low and had him sit. We now go for walks around the neighborhood and I open the app on my phone and track his oxygen from there.This is a must have if you have concerns with either you heart rate getting too high or your oxygen getting too low. I would and have recommended this ring to anyone that is looking for a way to track all of this information. It was a game changer for me.

I was SO IMPRESSED by this perfect little pulse oximeter that I felt compelled to share my opinion of it.I was hesitant to purchase any device, especially something for my wife, because I've been so unimpressed by convoluted user interfaces and difficult-to-use IoT gadgets in the past. But this little device is a true joy to use.The device itself has just one touch-button which simply lights up the screen to show its current readings. Its illumination can be set (by its apps) to low, normal or bright, and I recommend bright if you'll be viewing it outside or low if you'll be viewing it at night. Its clock and calendar will be set the first time it's connected to its apps. Again... the little device has no user interface other than an illumination button. That's all it does, since that's all that's needed.There's no on or off or anything else. You slip this onto a finger, it senses that it's being worn, so it turns on. If you take it off quickly, it resets and shuts down. If you keep wearing it, it begins logging once it's sure that you mean it. If, while it's logging, you take it off, it displays a short countdown from 10 to 0, giving you time to move it to a different finger, change your mind, or whatever. If you put it back on, the interval is ignored and logging continues. If you allow the countdown to expire, that session is ended.The device retains data for the most recent previous four (4) sessions. When you record a 5th session the oldest one will be replaced with the newest one. The device should "live" on its power cord. In other words, take it off and plug it in... so that it will always be fully charged whenever it's needed. You should think of it as a single charge per use. The battery is stated as 12-16 hours, so a full night's sleep will take it well down. So just be in the habit of keeping it plugged in.The mobile app for iOS is slick and perfect (and I assume that they did the same for Android). You do not "pair" the device's Bluetooth with your phone. Rather, the mobile app finds it and links to it. A single app can be used to collect the data from multiple devices if you wish. When the linkage occurs, any newly recorded sessions that the app hasn't already downloaded and stored will be obtained.The Windows desktop app works equally well. Using the included USB-A style interconnecting cord (you must use the one they provide for PC data retrieval) your device will be found and, as with the mobile app, any data that has not yet been downloaded, will be.Both mobile and desktop apps can show current and historical data and can dump to CSV (comma-separated value) or PDF report formats. And the use of one does not "take the data away" from the other. Each obtains any available session data that it hasn't already obtained.Having seen how well this works for my wife, I purchased a second device for myself so that we can use them at the same time. In one day she learned some very valuable information about the state of her respiration.Anyway, that's it. Five thumbs up for this little gizmo. It probably deserves your purchase.
