Masimo's 'MightySat' Fingertip Pulse Oximeter Now Available From Apple

I am still waiting for the cloaking device to appear on kickstarter...

I'm just waiting for the holodeck with Seven of Nine as DLC :D :oops:

I've always thought that Star Trek gives us the vision and human ingenuity will eventually give us the means.

I'd like to see Foreflight and other aviation EFB's be able to display this info on screen. For me, having this, along with blood sugar on 2-3 second intervals, with color coding would be good for pilots.

And, if you think 7% error is bad for an Oximeter, you should see the error rates for blood glucose strips...

How accurate is your blood glucose meter?

A major study found that almost half of meters do not meet the minimum required standards:


* For blood sugars over 75 mg (4.2 mmol): Accurate within 20%. For example, if your blood sugar is 200 mg (11 mmol), the meter must read between 160 (8.8 mmol) and 240 (13.3 mmol) at least 95% of the time.
* For blood sugars under 75 mg (4.2 mmol): Accurate within 15 mg. For example, if your blood sugar is 60 mg (3.3 mmol), the meter must read between 45 (2.5 mmol) and 75 (4.2 mmol) at least 95% of the time.

There is a new proposal that would require all results to be within 15%

Yep... if you're at 75, you could be at 65 mg/dl or 90 mg/dl, but honestly, for me, they're pretty tight, not at the extremes. It's just the panic of the OMG! These can be off and KILL YOU!

This is $18 on Amazon if you're willing to read the numbers on the device instead of your iPhone...

Sobering info.

More sobering is a lot of people say AW should not do Sp02 because it needs FDA approval, wont be accurate, and yet they have no idea the lack of accuracy of approved devices!

Thanks for posting.

The Apple Watch already has a pulse oximeter, but it's not enabled, likely because of the huge delay/effort needed for FDA approval.

The FDA's not wrong to test and regulate vital medical devices, and Apple certainly could not delay EVERY Apple Watch generation over that one feature. But it's a shame it can't happen quicker.

Top of the wrist is not a great place for gathering SpO2 data through reflectance, which I suspect Apple found out. Yes, it appears that there are some extra LEDs and sensors in there, but that alone doesn't make a pulse oximeter.

So, I wouldn't jump on the FDA. Nor is the FDA approval process all that horrible.

Source: I worked on SpO2 devices when they were first coming out, participated in FDA data collection and clinicals. There's a reason why the fingertip sensors are still dominant - they work.
