Why engineers are working to build better pulse oximeters
Visit any health-care facility, and one of the first things they’ll do is clip a pulse oximeter to your finger. These devices, which track heart rate and blood oxygen, offer vital information about a person’s health.
But they’re also flawed. For people with dark skin, pulse oximeters can overestimate just how much oxygen their blood is carrying. That means that a person with dangerously low oxygen levels might seem, according to the pulse oximeter, fine.
The US Food and Drug Administration is still trying to figure out what to do about this problem. Last week, an FDA advisory committee met to mull over better ways to evaluate the performance of these devices in people with a variety of skin tones. But engineers have been thinking about this problem too. Cassandra Willyard has dug into why they are biased and what technological fixes might be possible. Take a look at what she found out.

The big story
El Paso was “drought-proof.” Climate change is pushing its limits.
December 2021
El Paso has long been a model for water conservation. It’s done all the right things—it’s launched programs to persuade residents to use less water and deployed technological systems, including desalination and wastewater recycling, to add to its water resources. A former president of the water utility once famously declared El Paso “drought-proof.”
Now, though, even El Paso’s careful plans are being challenged by intense droughts. As the pressure ratchets up, El Paso, and places like it, force us to ask just how far adaptation can go. Read the full story.
