the issue is that it hasn't been fixed in decades, and is a known issue for these type of devices.
It's not a high priority because it only affects POC and THAT is institutionalized racism.
unless part of the reason it hasn't been fixed is because it's not a statistically significant difference that causes noticeable damage/risk
we need to know more than "0.2 to 0.4 fewer liters per minute of oxygen"
how much is normally provided? 1 liter per minute, or 10, or 20? what kind of tolerance is acceptable without any adverse effects?
what if science comes out 5 years from now that discovers hospitals have been delivering a bit too much oxygen which applies undue stress to the respiratory system, and non-whites have been given a more appropriate amount all along?
