New invention to solve a shocking problem: , in use for 50 years, that use ir absorption to measure blood oxygenation don't work with darker skin.

"Studies in 2005 and 2007 using pulse oximeters...showed that the presence of skin pigment resulted in an overestimation of oxygen levels in the blood...(resulting) in inaccurate tests for African American patients, often resulting in less supplemental oxygen in ICU settings".

@afewbugs First, yay! Also, near-infrared spectroscopy is so hot right now...
