I bought a AccuMed CMS50D1 from another members recommendation. I don't see that model anymore. Might be a CMS50DL that's currently sold.

What phone do you have? My Samsung S7 makes this measurement. I'm sure others do too.

We use a FaceLake CMS50DL. The price on both Amazon and eBay is up from where it used to be.

My Samsung S8 used to have this feature. It appears to have been removed from Samsung Health in a prior update. Does it still work on your S7?

DH has a SantaMedical.com SM-110 that he used when he was training to climb Mt Whitney. He dug it out a few days ago and it still works.

It's good to know which way is up, though. When he first put it on he held his hand up so I could read it and just about had a heart attack when I said "66, is that normal?"

That's the one I have, bought about 4 years ago and it's still good.

I've seen so many different models used in doctors' offices and hospitals that I don't think it makes much difference at all what brand/model you get. They're pretty simple devices.

I just measured pulse and oxygen on my S8 using the Samsung Health app (v. 6.9.0.055). I don't know how accurate it is, but the feature is still there.

MRG,

Yes it still works on my S7 through Samsung Health. I use it almost every day.

My Samsung Galaxy S7 Edge has a pulse meter, but doesn't do pulse oximetry. I bought a couple of Zacurate pulse oximeters with my FSA funds before everything blew up, and the 430DL/500E with the OLED screen is nice. I only paid $24.95, if you can find one and want to know a comparable price. The LED version (500BL) should be about $18-20.

On my S7 (non-Edge) oxygen percent is part of the stress measurement. The stress measurement measures heartbeat and O2 at the same time.

Oh! Thanks, I never added that to my S-Health home screen...or I removed it, because "stress" seemed like a bogus thing to measure with your phone. I still don't see why measuring pulse rate and pulse ox equals "stress", but thanks, I'll compare my phone's measurements to my Zacurate pulse oximeters! So far, they're both pretty much the same for pulse rate.

There are a lot of conflicting assessments about using cellphones for pulse oximetry. This article from a few days ago says NO. But this article in Pubmed from last year indicates otherwise. The app I looked at says it is for sports purposes only which, I would guess, means it hasn't been FDA approved for medical use but doesn't really answer the question of whether it is a helpful indicator.

I just did a quick test, doing 5 stress measurements, and my phone's measurements were within one point of the Zacurate pulse oximeter each time. I've been doing this with my pulse rate, too, since I had been using my phone for that in the past, so I'll try it under a few different conditions, like after exercising, but my spO2 doesn't usually vary by more than 4 or 5 points at most.

If the O2 reading drops below 93, time to head to the hospital.

Who knew. They hid it under "stress" I didn't have stress, only O2 issues living at 7750'.

Not quite. According to the Mayo Clinic, values under 90 are considered low. You should see a doctor mostly based on your symptoms, such as shortness of breath, but right now many hospital systems are above peak capacity, so if you are concerned about your spO2 but feel fine, please try to talk to a doctor or nurse on the phone first. Even before COVID-19, many health insurance providers offered "ask a nurse" services, and many doctors and health systems are now offering telemedicine.
