Determination of pressure conditions in an infusion system.

摘要

An infusion system (11) for infusing a fluid into a patient comprising an infusion device (15) for delivering the fluid in both a normal delivery pattern and a test pulse and a conduit (17) for conducting the fluid from the infusion device to the patient. The test pulse creates a pressure wave response (67) in the conduit. Abnormal infusion can be detected by determining the area between a baseline (77) and at least a portion of a pressure versus time curve representing the pressure wave response.
