    摘要: The present disclosure relates to a method and a device (10) for determining a hydration state of skin tissue. The device (10) comprises an interface (22) for receiving a data stream (100) comprising a plurality of PPG signals including at least a first PPG signal (104) indicative of a first wavelength range (72), a second PPG signal (106) indicative of a second wavelength range (74), and a third PPG signal (108) indicative of a third wavelength range (76), a processing unit (24) for computing at least a first combined signal (116) based on a first pair of signals (104, 106) selected from the plurality of PPG signals, and a second combined signal (118)based on a second pair of signals (108, 110) selected from the plurality of PPG signals, wherein at least one PPG signal of the second combined signal (118) is dependent on a tissue hydration level, and an analysis unit (26) for computing a hydration signal (34) indicative of skin hydration, wherein the hydration signal (34) is derived from the first combined signal (116) and the second combined signal (118).

    摘要: A system for evaluating patency includes a light sensor (128) positionable relative to a blood vessel to receive light from the blood vessel and convert the light into an image signal. Aphoto-plethysmography (PPG) interpretation module (115) is configured to receive the image signal and output pixel values in an image representing PPG information. An image generation module(148) is coupled to the PPG interpretation module to receive the pixel values and generate a PPG map to be output to a display for analysis.
