Read what twice, the post or the article?
In the lawsuit, Morales claims he knew the device "purported to measure blood oxygen levels and he believed it did this without regard to skin tone."
Apple's oximeter device operates by using light to hit a person's skin and then estimating how much light is absorbed by the red blood cells.
The lawsuit alleges that these machines were "significantly less accurate in measuring blood oxygen levels based on skin color." Further, the suit says that the Covid pandemic "confirmed the clinical significance of racial bias of pulse oximetry."
A Washington Post article from July claimed the technology was faulty because it did not provide "equitable" results and that its creators lacked "intentionality" of a racial sort when creating the technology.
Dr. Darien Sutton, an ABC News medical contributor, said, "How much light is absorbed tells you how much oxygen you have because red blood cells carry oxygen. The problem is that darker skin also absorbs light, so it can give you a falsely elevated reading."
