Pulse Oximeter Fingertip Bluetooth | Blood Oxygen Saturation & Heart Rate Monitor | Compatible with iOS & Android Smartphones

Great value

The device is pretty much like every other fingertip pulse oximeter. The tiny screen is functional, but the point is unless you are using it for exercise measurement, it won't be the primary display. With the Emay Oximeter App (I have Android) after you connect via Bluetooth it records data continuously. I use it primarily to monitor for sleep apnea and it has already proved valuable. Battery consumption is a non-issue if you use rechargeable batteries (AAA NiMH). As long as it can last 8 hours for your sleep that is all that is required.I would suggest before buying go to the Android/iPhone app store and check out the "Emay Pulse Oximeter" app and view the graphs and images to see if this is what you need. The graphs are highly detailed minute by minute with O2 saturation and pulse BPM. Also a very quick overview of min/max and thresholds with percentages at each state. Click on the summary graphs to view the detail graphs (this is not clear in the instructions).EDIT: 5/14/23 Suggestions: If you wake up in the middle if the night to use the bathroom, save the current set of data then restart a new set. This is in case you exceed the Bluetooth signal range (30ft) since this may lose the entire set, wasting the effort. This is also good in that you can spot check your readings (if you are using a CPAP) since you can't view live readings until after the file closes. This is BETTER than the CPAP event count, since it only tells you when you stop breathing, while the oximeter ACTUALLY gives your SPO2 which is the vital data. In conjunction with a CPAP this is the BEST way to have confidence that it is working correctly. The way that CPAP measures back pressure variance only INFERS performance, it is not the best data. Increased O2 is the entire reason for the CPAP and this is real data versus indirect pressure readings counting events. Wear this every night to gauge the best settings for CPAP such as min/max pressure and humidity. Experiment to find the best personal settings. Off topic, I suggest adhesive nasal strips as a drug free way of nose breathing using CPAP. I find this helps greatly on a continual basis.

Good

This thing is not the most accurate oximeter, and I know in the image I’ve shared that it’s two different fingers being measured but that is way too much drift for comfort.It’s still useful for gathering statistics, like if my O2 is dropping during chores around the house, but it also shifts dramatically.Either something is wildly wrong with me (it’s possible) or the measurement changing between these values is a sign of a bad device.It goes 94-93-83-85-86-87-93-95-92-85-87, in less than a minute. Now it’s definitely possible something is wrong with me causing this, but my other oximeter doesn’t do this as much.

The media could not be loaded. I've had this for a couple of years now and it still runs great. You just need to replace the batteries on it.You can turn the screen any four directions but I always keep mine upright since I am the one reading.It captures your Oxygen levels and shows a read alarm bell if your O2 is too low. It lets you know what your heartbeat is and shows your waves as well as how strong/faint your heart is beating.I have not tried to sync it to my phone but I think that's a great feature I will try in the future. This fits my current needs for monitoring as well as my hubby's.

If you’re considering purchasing the Pulse Oximeter Fingertip Bluetooth | Blood Oxygen Saturation & Heart Rate Monitor, I strongly urge you to look elsewhere. At first glance, it appears to offer everything you’d expect from a reliable pulse oximeter: sleek design, Bluetooth connectivity, and the ability to monitor blood oxygen levels and heart rate conveniently. However, after using it for just over a month, I am left thoroughly disappointed and frustrated by its poor performance and lack of quality.Initially, the device seemed to work fine. It provided reasonably accurate readings, and the Bluetooth function allowed me to sync data to my phone seamlessly. But the honeymoon period was short-lived. After roughly four weeks, the readings began to fluctuate wildly, giving me false readings that were not only inaccurate but completely misleading. On more than one occasion, the oximeter registered blood oxygen levels that were far below normal ranges—so low that it would have implied a medical emergency. Needless to say, these were completely wrong, as verified by a different, more reliable oximeter.The heart rate monitor soon followed suit, displaying numbers that were inconsistent with how I was actually feeling. At times, it showed my heart rate as drastically elevated when I was at rest, and other times it reported my heart rate as being dangerously low. These wild inaccuracies make the device not only useless but potentially dangerous for anyone using it to monitor their health in real time.The build quality of this oximeter is another area where it falls short. The materials feel cheap, flimsy, and it became evident that this product is not designed to last. After just a month of light use, it started to malfunction—the single button became unresponsive, and the display started flickering.For a device that is supposed to provide critical health data, reliability should be paramount. Unfortunately, this oximeter fails miserably in that regard. You’re better off investing in a device that has been properly tested for long-term use and durability. The Pulse Oximeter Fingertip Bluetooth may be affordable, but the saying “you get what you pay for” couldn’t be truer here. Avoid this product at all costs if you value accurate health monitoring.
