In the comments section of Small’s article, McCullough highlighted issues with fingertip pulse oximeters, describing the devices as “a technology that works better on lighter skin than darker skin.”

This is not a DEI issue. This is a technical issue based on the physical penetration of infrared light into skins of different colors. It has nothing to do with the socialist agenda. Just like laser hair removal works best on dark hair--getting it to work on light hair is a technical issue, not a DEI issue.

It's amazing the lengths racist leftists will go to to insert racism into everything.

Personal health trackers use red/infrared to sort out oxygenated vs oxygen depleted blood. The morning health stats from my Fitbit Charge 5 often take an hour before the overnight SPO2% appears in the stats.

My favorite tech using this technique is the vein finder for phlebotomists. See Vein finder
