Remind You to Breathe Well
A normal range of blood oxygen level is the key to starting a new day. During the night, when your SpO2 started to fall below the preset value, the prompt will be activated. Unlike the traditional sound alert system, it softly wakes you to change to a position that helps you breathe better. So sharing a bed with your partner won't affect his or her's rest. Checkme™ O2 ensures you wake up with an energetic morning.
Light & free, provide the most comfort.
Unlike duckbill design, the ring free your finger for movement.
So your hand won't feel constrained at all.

Accessories
Regulatory & Compliance
The Checkme™ O2 Pulse Oximeter is a lightweight, portable health wrist oximeter for use in sleep labs, long-term care, hospitals, and home use. The device is indicated for use in measuring, displaying, storing, and transmitting functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate for adult patients. It is intended for spot-check and/ or continuous data collection, and not continuous monitoring. The data and results provided by this device are for pre-check screening purposes only and cannot be directly used for diagnosis or treatment.
The product is FDA cleared (FDA clearance link). An individual customer needs a prescription to purchase The Checkme™ O2. Please email the Rx to us at: support@getwellue.com.
I own two Wellue devices and upon hyperventilation, with completely still hands, to test the device against the older device I have, the older device gives expected readings and this new device gives wildly lower readings. How can we resolve?

Excellent sleep oxygen monitor
This little monitor does the trick. It is not that intrusive so it doesn't get in the way of my arm moving at night, but the sensor also stays put (been using it for about a week now and haven't had it come off). The software for the smartphone calculates numbers like the amount of time the saturation is >95 and the number of drops 4% or greater during the measured period. With the software for the computer, you can save this in report AND data exports to allow you to analyze to your heart's content.

App Needs Improvement
The product is superior.
Unfortunately, the app is not very good. For one, the top of the PDF page omits the name and other information about the user. It is completely plank. This makes it hard to electronically share with your provider since it doesn’t even show your name. The only way to share it is to print out the page, complete the top with your name, birthday and other demographics and fax it to your provider. Obviously a very manual and antiquated process.
Also, on the PDF, the grid lines are so small so it is very difficult to see the fluctuations amount. Your literally have to count the very small grid lines to quantify the fluctuations. This needs to be improved.
The app uses very small print, which make some sections difficult to read.

Very helpful and informative
Glad that I bought the product. It gave me information about my quality of sleep and what I should do to get better sleep. Easy to use and reasonably comfortable to wear at sleep.
Suggestion to company: Enlarge the scale for the Motion chart as it wouldn't spike even when I am getting to and from the washroom.

Some peace of mind.
After my wife had departed and then come back to her body, she was put on oxygen again. Too much oxygen is what killed her in the first place, so I needed a device where I could monitor her daily status so I could adjust the flow meater to keep her from passing again. This device has an alert for low level of O2, but it should also have one for a high level of O2. At any rate I use the daily report so I can see her average throughout each night and I use the alarm if she goes below 87. I have been able to adjust the flow meaters on the two machines I have in the house and now have them each dialed in so she will average 93. The Checkme device has allowed me to accomplish that task.

The wristband is my only concern. If you have arthritis in your finger's, it is hard to fasten the band.

It's a great device that my wife wears 24/7 she wears to go to sleep it vibrants when her oxygen levels drop so can regulate her oxygen day and night she's on oxygen 24/7 thank God for this wonderful device to make it easier for me since I'm my wife's care taker .

Amazing device!
I would give this unit 6 stars if I could. Every CPAP machine should come with a device like this to help evaluate what you are doing right and what you are doing wrong. I am a side sleeper and it is uncomfortable to sleep in that position with the CPAP mask on. Over a couple weeks worth of monitoring I have concluded that my apnea is no worse sleeping on my side without CPAP than sleeping on my back with CPAP. What a relief to be able to pull my mask off halfway through the night and sleep the remainder of the night on my side without worrying. If I happen to have an apneic event and my O2 levels start to drop, then the monitor wakes me up before my level slips any further. It is very comfortable and I have no reservations about using this every night and I will from now on, especially when I do not have access to a CPAP like while traveling or backpacking etc.

Best investment
My husband's fingers were so cold that we could not get an accurate O2 reading even with the finger tip professional pulse ox. Using the ring read it correctly. The alarm let me know when his oxygen got low so I could adjust it. You can set the level as to when the alarm goes off. If you have it connected to your phone, you can see the pattern for the duration that it is on per day. When I used it, I discovered that I was having sleep apnea with low oxygen quite a few times during the night. I had no idea this was happening, so this device may have saved my brain and heart from more damage. I highly recommend this device.
