1. A system for determining an autonomic nervous system (ANS) state, comprising:
a camera to generate image data of a patient;
a display;
a memory that stores machine executable instructions; and
a processor coupled to the memory, the display, and the camera, wherein the processor executes the machine executable instructions to:
receive the image data indicative of the patient from the camera;
receive a physiological signal of the patient from a sensor coupled to the patient;
identify the patient in the image data based on at least one patient feature in the image data;
identify a first time corresponding to a start of physical contact between a caregiver and the patient based on the image data;
determine that a duration of the physical contact extends from the first time to a second time based on the image data;
in response to determining that the duration of the physical contact exceeds a threshold, set an interaction flag to indicate that the physical contact qualifies as an external stimulation to the patient;
in response to setting the interaction flag, continue to monitor the physical contact to identify a third time corresponding to cessation of the physical contact based on the image data and determine a measure of an autonomic nervous state (ANS) of the patient based on a response of the patient to the physical contact between the first time and the third time, wherein the response comprises patient activity of the patient based on the image data and a change in a physiological parameter of the patient based on the physiological signal of the patient; and
instruct the display to output the measure of the ANS of the patient.
