Abstract
A device for non-contact measurement of blood oxygen saturation (SpO) in a mammalian subject including a camera and one or more arrays of LEDs each having a first set of LEDs emitting near infrared (NIR), and the second set of LEDs emitting orange light located in an optical path adapted to transmit reflected light from a subject to the camera. A controller transmits a camera trigger to the camera, and is further coupled to transmit control signals to the one or more arrays of LEDs. A processor receives photoplethysmography (PPG) data signal values from the camera. The PPG data signal values are present in the reflected light and include pulsatile and non-pulsatile components. The processor determines SpOvalues from the PPG data signal values from the measured ratios of pulsatile to non-pulsatile components of the PPG signals.
