摘要:
Systems for calculating extent of congestive heart failure (CHF) and/or identifying exacerbation of CHF. In one embodiment, a system includes smartglasses configured to be worn on a user's head, and an inward-facing camera and a sensor, both physically coupled to the smartglasses. The inward-facing camera is mounted more than 5 mm away from the head and captures images of an area comprising skin on the user's head, which is larger than 4 cm{circumflex over ( ;)}2. The sensor measures a signal indicative of a respiration rate of the user (respiration signal). The system also includes a computer that calculates the extent of CHF based on: a facial blood flow pattern recognizable in the images, and respiration rate recognizable in the respiration signal.
