摘要：
This document discusses, among other things, systems and methods for managing pain of a subject. A system may include a sensor circuit configured to sense a respiration signal and a heart rate signal. A pain analyzer circuit may determine respiratory cycles and respiratory phases in a respiratory cycle, and generate one or more signal metrics indicative of respiration-mediated heart rate variation. The pain analyzer may generate a pain score using the signal metrics indicative of respiration-mediated heart rate variation. The pain score may be output to a user or a process. The system may include an electrostimulator to generate and deliver closed-loop pain therapy according to the pain score.
