摘要：
Aspects of the invention relates to systems and methods for monitoring an intravenous (IV) line functionality of an IV device. The system includes an IV catheter to be inserted into the vein of the living subject, at least one pressure sensor in fluid communication with the IV catheter to acquire peripheral venous signals； and a processing device. The processing device receives the peripheral venous signals from the pressure sensor, performs a spectral analysis on the peripheral venous signals to obtain a peripheral venous pressure frequency spectrum, and determines an IV line functionality of the IV catheter in real time, wherein the IV line functionality of the IV catheter indicates IV infiltration when amplitude decreases greater than a first threshold are detected from the peaks of the peripheral venous pressure frequency spectrum.
