Calibration of Contactless Pulse Oximetry [PDF]
Anesthesia & Analgesia, 2017 BACKGROUND: Contactless, camera-based photoplethysmography (PPG) interrogates shallower skin layers than conventional contact probes, either transmissive or reflective. This raises questions on the calibratability of camera-based pulse oximetry.
