Remote Photoplethysmography (rPPG): A State-of-the-Art Review
, 2023 Peripheral oxygen saturation (SpO2) and heart rate (HR) are critical physiological measures that clinicians need to observe to decide on an emergency intervention. These measures are typically determined using a contact-based pulse oximeter.
