Thanks, FDA! You've saved us from pulse oximetry!

I looked into apps that purport to do that using your phone. None of them seem to be thought to work very well, so I'm not sure how the apple watch does.

But a Class II medical device? Risk to the patient? Please.

[jon-nyc]

I read about that, but never knew the specific reason.

One would think by the time you had a pulse ox issue you would have very significant other issues. It’s not like you get up cook breakfast have a nice convo put your finger in a pulse ox and say holy shit call the ambulance.

[jon-nyc]

Well, that’s sort of what people are reporting. Low oxygenation without feeling short of breath.

Those were my thoughts as well. I see no danger, other than an inaccurate reading. I suppose a false "normal" reading when the patient is in trouble would be a problem, but, c'mon.

We bought a Pulse/OX meter a while ago. We check our temp and O2 every morning. So far, so good!

A lot of pilots carry a Pulse Oximeter. It can be important if you are flying regularly unpressurized at high altitude, especially at night.

Some later model planes have one built into the instrument panel.

You can find them in pilot shops, like this: https://www.sportys.com/pilotshop/oxi-plus-pro-pulse-oximeter.html

I wonder what a Venn diagram of Apple Watch wearers and people who had a 8-10% drop in pulse ox and didn’t notice it would look like.

[jon-nyc]

Seems like they double the price when they put the word 'pilot' on it.

[jon-nyc]

I think you're still missing the script here, Loki. What is being reported is a drop in sats without SOB. Google 'silent hypoxia'.

You can be quite short of oxygen and not necessarily notice it. When I was in the hospital last December they fluid overloaded me with IVs caused my normally 95+ SPO2 to drop to high 70's in room air. I never noticed it and was not short of breath. In this case you are short because COVID is damaging your lungs asymptomatically.

If it’s a matter of going from 92 to 88 without knowing it I get it...I am not buying a 98 to 88 drop silently.

You should see what they do for "medical" devices.

You could easily drop from 99 to 88 and never notice.

Or “MIL-SPEC”.

Decades ago, heart surgeons were trying a different type of suture to close the sternum when finishing a CABG. They used a suture called "Mersiline" (not sure if I spelled it right). It was a real suture, and was meant to replace the traditional use of wires to approximate the two halves of the sternum that had been sawed apart.

I guess Mersiline was fine, but was a bitch to get that last knot down to get a nice and tight closure. You had to get that knot really down, tight, on the sternum to get it to hold.

One of the surgeons I worked with had a brilliant idea. He took a regular teaspoon, and cut a notch in the tip that would be big enough to accommodate the suture and allow him to apply good pressure while pushing down on the knot to bring the suture "home."

It worked really great, but, ultimately, it was forbidden because it was not a "medically approved device."

Merseline was eventually abandoned, and we went back to standard wires.

[jon-nyc]

Still have the wires in my chest. Occasionally the TSA guys take notice.

[George K]

Wires are forever.
