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

Works great. Simple to use and linked with the app on my phone with no issues.

I haven't used the app yet, but overall, the actual device itself works great for me. I love how quickly it turns off so it doesn't waste battery and has been pretty accurate for me.

Its simple and very easy to use. You will have to download another app, but other than that its pretty much very nice.

it does exactly what it says, it uses a 3rd party app and that works well. it tracks oxygen levels and charts it for you. ecg also. it shoed my levels dropping low early then higher later. the reason for 4 stars is the battery life. batteries last for 1.5 nights. not that handy eating batteries but it does run sensors all night. for the price its amazing. it will tell you what your looking for and do it easily without setup or connection hassels

A pinch sensitive to positioning on your finger. Use your middle finger and get it in as deep as it can go (comfortably) - on any of these sensors. Sure, you can use any finger, but the larger the skin surface and blood flow, the more accurate the measurement. The laser is basically looking at the color of your blood - through - your skin. So wash your hands (engine oil, sun screen, etc will degrade the reading) and watch out for callouses. The sensor doesn't care about the color of your skin. It cares that it can bounce light off the capillaries I didn't try the the blue tooth feature or download the software, but I did get a reading in my blutooth list that it had found it. It can only be registered for use if the software is installed. My phone would not connect to it because I did not download the software.

I purchased this to help me keep track of my oxygen levels more regularly. It works great. I really like the app feature that keeps track of all of my information on my phone. Small and lightweight, easy to carry. Very affordable.

I have sleep apnea. A sleep test will cost on the order of $250 each. One of the most important pieces of data a sleep study tests for are your levels of blood oxygen (SpO2). I used this pulse oximeter, along with the free app I downloaded on phone to graph my blood oxygen while sleeping. I discovered what no pulmonologist ever told me. My sleep apnea is NOT caused by any blockage in my throat from the tongue pushing back during sleep. Which is the most common cause of sleep apnea, and the default answer of many doctors. Rather, I discovered my sleep apnea is caused by "shallow breathing".See I also have inflamed vocal cords called Vocal Cord Dysfunction bought on by acid reflux. Since air has to pass through the vocal cords, the difficulty becomes greater while sleeping. I figured this out by experimenting with different sleep apnea hardware, then taking an overnight pulse oximeter test. I found it odd that wearing mouth guards with tongue depressors (keep tongue from falling back) did not help my SpO2 reading much at all. It was still below 90 pct for up to 30 minutes a night. Ideally you want all your sleep time above 90pct. Also, my overnight sleep apnea test from clinic, and snore noise test revealed I had very little snoring which indicates the tongue is likely not blocking the airway. The CPAP machine never worked for me because my inflamed vocal cords caused pushback from the airflow and I would wake up in the morning feeling nauseous. Plus, CPAP machines are just hard to get used to-period.I found a study on oxygen concentrators that made me want to give those a try. These machines give you a flow of concentrated oxygen. The amount of airflow is very mild and not even noticeable. I tried different settings, and for me I like 2 liters per minute(note average person breathes 7 liters a minute). At the 2 liter setting I am getting 75pct oxygen (compared to 21pct oxygen that normal room air has). In oxygen therapy more airflow is not necessarily better.This oxygen rich therapy while using a nose cannula, along with wearing a chinstrap to keep my mouth closed so I breathe in and out my nose only at night, to ensure I was getting the oxygen therapy. My sleep readings now are like a straight line graph of 95 pct SpO2. I never achieved this level, ever! All night it only dipped to below 90pct for 2 seconds which is well within a normal range.Hope this helps.

I bought this to follow my oxygen levels while I was sleeping. First off, the instructions are just barely adequate. I downloaded the app onto my google phone (it doesnt work with my amazon/kindle fire reader), updated the software, and good to go.A couple of negatives here; while it saves the info in a graphical form, the data cant be sent or opened as a spreadsheet for manipulation. There is a specific order to how to turn off the oxygen meter or it wont save the data you just recorded. It eats AAA batteries, goes thru a set a night but the battery indicator will let you know in advance. The meter O2 number rapidly flashes sometimes, figured out this is due to the O2 number being below their preset alert number (I think it is 88%?) but no mention of this in the manual or after contacting their customer service (they asked me to send a vid of the "problem"). Overall, i give the meter a 4, good value for the money; and the instructions, manual etc. I give a 2.
