Patent Images
1. A system comprising:
- a physiologic monitor configured to obtain physiologic information about a patient; and
a processor coupled to the physiologic monitor and configured to receive the physiologic information about the patient, the processor comprising;
a symptom status detector including a first fuzzy logic inference module configured to derive a symptom status from the physiologic information using a first fuzzy logic inference; and
a disease status detector coupled to the symptom status detector, the disease status detector including a second fuzzy logic inference module configured to derive a disease status from the symptom status using a second fuzzy logic inference.

Abstract
In an example, physiologic information about a patient can be obtained and mapped to a first set of fuzzy logic membership functions, and a symptom status can be derived from the mapping of the physiologic information using a first fuzzy logic inference. In an example, the symptom status can be mapped to a second set of fuzzy logic membership functions, and a disease status can be derived from the mapping of the symptom status to the second set of fuzzy logic membership functions using a second fuzzy logic inference.
