First Claim
1. A method of operating an infusion device to deliver a fluid influencing a physiological condition to a body of a user, the method comprising:
- identifying a current site location on the body of the user associated with a sensing arrangement providing sensed measurements of the physiological condition in the body of the user at the current site location;
determining one or more performance metrics associated with the current site location corresponding to operation of the infusion device to deliver the fluid in response to the sensed measurements; and
providing sensor site feedback in a manner that is influenced by the one or more performance metrics.

Abstract
Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of operating an infusion device to deliver fluid to a body of a user involves identifying a current site location on the body of the user associated with a sensing arrangement providing sensed measurements of a physiological condition in the body of the user at the current site location, determining one or more performance metrics associated with the current site location corresponding to operation of the infusion device to deliver the fluid in response to the sensed measurements, and providing sensor site feedback in a manner that is influenced by the one or more performance metrics. In one or more embodiments, the sensor site feedback includes recommended sensor site locations for rotation or replacement of the sensing arrangement determined based on historical data associated with the user for different sensor site locations.
