1. A condition classifying device comprising:
an input interface configured to receive first data corresponding to a blood refilling state after ischemia of a subject, and second data corresponding to a physiological parameter that exhibits changes caused by vasodilation of the subject;
a processor configured to perform a classification of a condition of the subject related to sepsis based on the first data and the second data;
a compression controller configured to drive an actuator to cause an ischemic state in the subject;
an output interface configured to output a result of the classification,
wherein the condition of the subject includes one of a warm shock state and a cold shock state,
wherein the input interface comprises a pulse oximetry probe, and
wherein the processor is configured to:
drive the actuator to cause ischemia in the subject,
in a blood refilling state after the ischemia, receive the first data and the second data through the pulse oximetry probe,
detect a change in the first data and a change in the second data after the ischemia,
based on the change of the first data and the change of the second data after the ischemia, perform classification of the subject into the warm shock state and the cold shock state.
