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 rest. Checkme™ O2 ensures you wake up with an energetic morning. 

Wellue Checkme O2 Max ring sensor with vibration vs tradional duckbill sensor without vibration.

Lightweight & free, providing maximum comfort.

Unlike duckbill design, the ring free your finger for movement. 

So your hand won't feel constrained at all.

Continuous wrist oximeter better than nonin wristox2, nellcor, contec, beurer, lookee sleep monitor and masimo.

Comparing to duckbill sensor, Checkme O2 Max ring sensor stays fixed and more comfortable to wear.

Duckbill Sensor

  • Sensor goes off easily

  • Limited finger movements

  • Finger gets numb

Ring Sensor

  • Stay fixed

  • Movement Free

  • Like wearing nothing

My wife Rosemary has stage 4cancer

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 .

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.

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.

Much more comfortable for long term wear than the O2 ring

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.

I'm very impressed with the Checkme O2 Max!

The Checkme O2 Max from Wellue is a sophisticated device that is easy to use and I'm very impressed and grateful for its assistance.   I first was aware of apnea in my 30's when I would startle awake and sit up gasping for breath.  These episodes seemed to improve over the years (I'm now 75) and I  attributed occasional morning headaches to sinus/allergy issues though my husband of 30+ years has often mentioned having to nudge me to re-start my breathing in the night.  I was prompted to look up O2 monitoring apps after a recent middle of the night trip to the emergency department after waking with unaccountable rapid/forced breathing and subsequent confusion.  Although the cause wasn't identified, and I fully recovered, it did take about 10 hours for my B.P. to return to it's usual levels.  It wasn't until a few days later my husband suggested the incident could have been apnea-related.

I purchased Wellue's most expensive pulse oximeter because it wasn't much more money and offered the 2-minute sampling rather than 4 minutes, has a powerful (7 day) battery plus it had the option of vibration or sound alerts for low O2 levels.  I also discovered it could be set for a sound alert if the sensor comes off your thumb (only 2 times in my 13 days of records so far),  and that I can reduce the threshold for the alert below 90% (initially I was aware of all of the alerts while sleeping and so I reduced the alert threshold to 88% so my brain would be less likely to habituate to the vibration--and so I might sleep better).  The summary reports on the smart phone app are very helpful and I also keep the more detailed records on my desktop via the O2 Insight Pro app (Wellue kindly quickly supplied an improved cable for this latter application to work reliably every time--otherwise it was a bit hit or miss on my older PC).  My husband has noticed that my sleeping is now much quieter (I've always been a snorer and now apparently I rarely do)---and that I seem to sleep more deeply.  I feel refreshed on waking up after using the Wellue Checkme O2 max and am now mostly unaware of the vibration alerts. In glancing through the records, I'm wondering if there might be some sort of subtle training/learning going on since after one week the depth of the O2 drops appears to decrease, and this is even more apparent now after these almost two weeks of use.

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.

Great monitor with helpful support

I have bought and owned at least 4 different spo2 monitors such as checkme doctor, checkme max, checkme be4 max, i own all and have tested them all and they all matched readings from 1 hand using at same time on different fingers

and can say there accurate i got my 1st 1 in 2019 and then bought a family member the new max model in may2021 due to there ill health and due operations on there lungs and a weak heart

The max model has spo2 monitor plus a pulse rate monitor which both have an alarm system when they drop below a certain level then it beeps and vibrates

Support are very helpful with replacements when it comes to replacement charge/data cables or of finger sensors am a restless sleeper and due this sensors have malfunctioned and wellue have kindly replaced sensors as there warranty and guarantee is for a full year from purchase and there fast to reply within 24 hours so am very happy with there support system

Provides Good CPAP Corroborating Info

I use the Checkme O2 Max to confirm the information provided my ResMed AirSense-10 CPAP machine. It is nice to be able to see that the info from the two devices almost always confirms each other's report. Yes, the device is a bit pricey, but its a real bargain compared to a local health supplier who charges $50 for a one-night recording oximeter test. To provide full disclosure, I am a hopeless addict to home healthcare electronic devices. ;)
