Abstract: The invention provides an intravenous (IV) dressing system that helps secure an IV catheter to a patient while simultaneously using embedded peripheral venous pressure (PVP), impedance, temperature, optical, and motion sensors to characterize properties of the IV system (e.g., infiltration, extravasation, occlusion) and the patient's physiological parameters (e.g., heart rate, SpO2, respiration rate, temperature, and blood pressure). Notably, the system converts PVP waveforms into arterial BP values (e.g., systolic and diastolic blood pressure).
