While I’m sure the obvious systemic issues contribute to not looking for alternatives, that does sound like largely an issue inherent to optical pulse oximeters. Engineers aren’t miracle workers, they can’t change physics to their liking.
I’m sure pulse oximeters now are more accurate than they were 20 years ago. The fact we’re still using them is because no alternatives have been found which are as easy to use, reliable, and non-invasive as pulse oximeters, even with the known downsides.
Engineers aren’t miracle workers, granted. Which is why it is their responsibility to thoroughly test the devices they design and document their limitations. It’s then on the medical industry to train doctors and nurses on those limitations.

As I said, this continues to be a problem into the present day. COVID-19 patients with dark skin would suffer from hypoxia that pulse oximeters would fail to detect, leading the medical staff to fail to administer supplemental oxygen. That’s probably happening somewhere on earth as I type this.
Do the little lights in the device need to be brighter, or have a brighter mode? Does their need to be a switch on the side? Can our cultures handle a medical device with a “white people | black people” switch on the side?
