The present invention includes systems and methods for detecting fluid flow into or out of a port chamber or a reservoir of an implantable medical device utilizing a pressure sensor and calculating the fluid status of the reservoir. The system detects characteristic pressure profiles associated with fluid flowing into the medical device, out of the medical device, and also whether one or both of the port chamber or reservoir are substantially empty or substantially full. In addition, the present invention may generate a sensory cue to a clinician to indicate the fluid status.
