oximeter

Drawing inspiration from the way plants breathe, a group of researchers at Tohoku University has created a paper-based magnesium-air battery that can be used in GPS sensors or pulse oximeter sensors.

There were no issues at birth and the pulse oximeter test was only provided as part of a trial, she added.

It found pulse oximeter devices could be less accurate for people with darker skin tones, making it harder to spot dangerous falls in oxygen levels.

It could, for example, result in patients not being able to see a doctor as -- based on the readings generated by the pulse oximeter -- they are deemed to be healthy.

Inaccurate pulse oximeter readings are more common in Black patients than non-Black ones.
