(GIST OF SCIENCE REPORTER) Smartphone’s Camera and Flash Measure Blood Oxygen Levels at Home

[December-2022]

Researchers from the University of Washington and the University of California San Diego have demonstrated that smartphones can detect blood oxygen saturation levels as low as 70%.
In this technique, participants place their finger over the smartphone’s camera and flash, which utilizes a deep-learning algorithm to determine the blood oxygen levels.
The smartphone correctly identified if a patient had low blood oxygen levels 80% of the time when the team gave six subjects a controlled dosage of nitrogen and oxygen to artificially lower their blood oxygen levels.
