Enhanced Diagnostics for a Telepresence Robot
A telepresence device may autonomously check patients. The telepresence device may determine the frequency of checking based on whether the patient has a risk factor. The telepresence device may include an image sensor, a thermal camera, a depth sensor, one or more systems for interacting with patients, or the like. The telepresence device may be configured to evaluate the patient's condition using the one or more sensors. The telepresence device may measure physiological characteristics using Eulerian video magnification, may detect pallor, fluid level, or fluid color, may detect thermal asymmetry, may determine a psychological state from body position or movement, or the like. The telepresence device may determine whether the patient is experiencing a potentially harmful condition, such as sepsis or stroke, and may trigger an alarm if so. To overcome alarm fatigue, the telepresence device may annoy a care provider until the care provider responds to an alarm.
