Special Series: Racial Bias and Pulse Oximeters Part 2—What Went Wrong?

About this episode:

Pulse oximeters—devices used to read blood oxygen levels in hospitals and at home—are far less reliable for people with darker skin tones. Falsely normal readings have the potential for clinical staff to miss life-threatening conditions.

In this three-episode special series, we explore a longstanding issue that only caught the nation's attention in recent years. In episode 2: What went wrong, including inaction from manufacturers and regulators, market forces, and racism in medicine that goes beyond this one device.

Listen to Part 1: A Problem Hiding in Plain Sight.

Listen to Part 3: Fixing Pulse Oximeters.
