Any advice on an oxymeter to purchase, or components/features to look for? They all seem to be the same, but vary in price from $20-$300. Reviews on websites are just garbage.

There are ones that clip onto a finger and also ones that you can wear while sleeping. I have one of the wearable ring ones (Wellue/O2Ring/Viatom, etc) and am happy with it. My oxygen levels are good through the night and my resting heart rate is much lower than I expected it would be.

Search Reddit, lots of doctors and med students discussing which of the cheap ones work. Nearly all are sold out though. I bought this one last night based on Reddit feedback for $35 but it's already sold out: https://www.amazon.com/gp/product/B01HSAG8BE/ref=ppx_yo_dt_b_asin_title_o00_s00 https://www.amazon.com/gp/product/B01HSAG8BE/ref=ppx_yo_dt_b... If you've got $300 to spare, this one is allegedly FDA approved: https://www.masimopersonalhealth.com/products/mightysat-fingertip-pulse-oximeter-with-bluetooth-le-rrp-pvi https://www.masimopersonalhealth.com/products/mightysat-fing...

  Thanks! A place called Medkioskinc.com apparently still has stock of those (at least they did ten minutes ago when I looked), for anyone reading this thread.

My S8 has a "Samsung Health" app, that measures Oxygen Saturation under the "Stress" section. It uses the sensor next to camera (also used for Heart Rate). I've no idea how accurate it is though. Some googling and I found a related paper: "Accuracy of Smartphone-Based Pulse Oximetry Compared with Hospital-Grade Pulse Oximetry in Healthy Children" DISCUSSION AND CONCLUSIONS: Smartphone-based pulse oximetry is not inferior to standard pulse oximetry in pediatric patients without hypoxia. [1] However in this case you _are_ trying to test for hypoxia... Another link answering the question "Should smartphone apps be used as oximeters": CONCLUSIONS It is not physically possible to measure SpO2 using current smartphone technology. The two published studies which assessed smartphone oximeter apps (Digidoc and Samsung) raise serious questions about the diagnostic accuracy. The Samsung app has been withdrawn, and the claim that oxygen saturation can be measured indirectly through “stress assessment” is false.

Many smartwatches have the hardware to measure oxygen saturation, though not all have it enabled. For example, all Apple Watches have hardware for it, and rumors (from before Covid was declared a pandemic) suggested that the next OS version would enable it. Depending on your worry level, you might want to wait to see what happens. Also, this article mentions that people are subconsciously altering their breathing/heart rate when affected. If you already have a smart watch that is tracking your heart rate, you may be able to infer this condition by monitoring heart rate deviations from normal.

  This is super-interesting. Could be extremely powerful along with contact tracing.

My mother has interstatial lung disease. We got her a Zacurate brand pulse oximeter. https://photos.app.goo.gl/MVkCa7GH9NuEbgbL6 https://photos.app.goo.gl/MVkCa7GH9NuEbgbL6 Model 500E which was recently released then. It is rated at 2% +/- but their documentation says that their lab testing gives 1% +/- Does not have memory as I did not need that so you will be able to spot check and not have, for example, overnight readings.

I have a OX-HC W512, which is certified for medical use. I wanted to make sure it would be reliable and correct. In addition to having the alarm that you need for sports, it can also track heart rate and log your data. Later, you can then connect it via USB (or Bluetooth if you buy the upgrade) to do interesting analysis such as correlating your pulse and oxygen saturation with the route that you drove (mountain bicycling). It's super nerdy, but a great toy for making your exercise feel like science.
