Wellue Pulse Oximeter Fingertip Blood Oxygen Saturation Heart Rate Monitor with Batteries and Lanyard Bluetooth FS20F White

Pairs easily with app to record data
This pulse-oximeter device is easy to use. Just insert the included batteries, power it on, and clip it to your finger for a quick check of your pulse rate and blood oxygenation levels. I already had a pulse-ox device, but got this one in order to keep a record of my oxygenation levels. To do this, download the free ViHealth app from the Apple App Store or Google Play. In order to record your data, you need to turn on the pulse-ox device first, then open the app. The first time you do this, you will need to pair the device with the app via Bluetooth. Then just leave the pulse oxymeter on your finger, the app open, and your phone or tablet on, and you can watch your pulse and blood oxygenation levels being recorded on the home screen. The recording stops if you turn off your phone/tablet, or shut the app. Of course, it also stops if you take the pulse oxymeter off of your finger or power it down. Recorded data can be viewed on the History page of the app, by day, week, or month. If you have an iPhone, you can have ViHealth export the data to the Apple Health app, too.This is definitely a useful device to have if you have oxygenation issues due to Covid or any other cause. It’s not terribly useful for trying to record data overnight, since you have to manage to keep the device on your finger, and your phone or tablet from going to sleep. Also, which it claims it comes with an “alarm” for low oxygen, there is no alarm that sounds. If your oxygenation saturation drops below 88% or your pulse goes over a particular level (I think it’s 140), what happens is that the number displaying your sats or pulse flashes very rapidly.All in all, this is a fairly affordable device to get if you want to keep a record of your pulse and blood oxygen saturation levels over time.

Good value, solid device, extras may cost more
The oximeter is probably the equivalent of similar devices at 2X the price. Upon going to the Wellue website I found only more expensive measurement and diagnostic tools ($50 to $250) and not this entry-level product (FS20F), which is probably what sellers refer to as a “loss leader.” Although the FS20F synched up through Bluetooth, it appears that any coherent tracking of a user’s history requires subscription to Welllue’s tracking and cloud services. I think I’ll remember my O and P levels with my own occasional, unrecorded readings of the device.As for the device, it seems accurate and is easy enough to use. Just several clarifications: 1. You will need to put the oximeter on a finger of the right hand and not the left, unless you plan to read the screen upside-down. 2. You need to press the button to “activate” the device for finger insertion. However, you do not need to re-press the button upon removing your finger as the device will de-activate automatically. 3. Upon de-activation, the power remains on and the batteries will eventually discharge. To preserve battery life (2 AAA’s) simply remove them (the instructions suggest after 30 days). 4. Be patient with inserting the lanyard. (I had success after wetting and winding the loop, which I then inserted in the hole facing me before pulling it out from the hole on top.)Finally, don’t panic if your reading of the oximeter is closer to 90 than to the recommended 95-100. The guidelines for reading the number, I’m convinced, are overly insistent re the top number; overly alarmist re the bottom.

Also Works on My TOE… For Hands Free Monitoring over time
This little Bluetooth device (plus the ViHealth APP from iTunes or Google Play)tracks Oxygen Saturation and Pulse Rate over time. Its readings pretty well match what I see at Doc Office, and it’s AMAZING it can do it for under $20, when similar devices go for more than $150!!!Out of necessity and invention, I discovered today that it works just fine on a TOE, too!I was talking to my doc on a call and she was saying SPO2 needs to ideally be in the mid-90’s or higher, and I reminded her mine is historically quite a bit lower… down in upper 80s to low-to-mid 90s tops.She asked what it looks like while I’m sleeping and of course who knows? I don’t check it like that.But I supposed I could, if I used my Bluetooth monitor and wore a GLOVE or something to keep it on.Then I thought. let’s verify what is RIGHT NOW over time. But having to hold the device on my FINGER while I sit here and try to type… I can’t get much done. I kind of need my HANDS!But I said to myself, “Self, I said, you have a few other monitoring appendages available not doing much while you type. Wonder if this thang will work on the TOES!?”And sure enough… same reading; same numbers, fits fine…Great! So now I can get a much longer-time-scope reading SPo2 from my FOOT while I keep working.Perfect!
