Philips device measures blood oxygenation via camera

A new medical device from Philips aims to accurately measure absolute oxygen saturation of arterial blood using a camera-based monitoring technology that quantifies tiny changes in skin color.

Researchers from Philips have detailed in a new study a new contactless monitoring device for measuring blood oxygenation levels—an important sign when monitoring patients—by detecting tiny changes in skin color. It uses a proprietary camera-based technology that detects light reflecting from the patient's forehead to measure the oxygenation levels and is the first of its kind.

"Vital signs monitoring is crucial across all types of care settings, but for patient populations with specific conditions, managing their care in a less intrusive way is critical in order to avoid unnecessary distress," said Carla Kriwet, CEO of Philips patient care and monitoring solutions.
