Abstract
A system for measuring capillary refill time includes a wearable device and a control unit. The wearable device includes a force sensor to obtain a force signal and an optical sensor to obtain an optical signal. The system ensures that an applied force is acceptable in both magnitude and duration, and that a duration over which the applied force is released or removed is acceptable. These factors can establish that a capillary refill time determined or calculated therein is accurate. The system can also determine the capillary refill time based on the force and optical signals obtained by the force and optical sensors, respectively.
