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 create 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 3: How engineers are working to improve the design of pulse oximeters, and how advocates from across the medical industry including patients and students are leading efforts to keep the pressure on to improve equity in pulse oximetry…and beyond.
