A real-time non-invasive system monitoring haemodynamic parameters in critical conditions by peripheral blood pressure wave analysis

A non-invasive measurement platform for peripheral blood pressure monitoring and integrated diagnosis based on a piezo film pulse sensor and suitable processing algorithms running on a laptop PC has been developed. Different parameters (such as cardiac output and systolic pressure variation) for integrated haemodynamic management in critical conditions are determined by using mathematical and/or physiopatological models. Moreover, once connected to classical patient monitors, the system computes further parameters used for haemodynamic assessment of critical patients. Experimental results of the clinical in-vivo validation in operating theatres and in intensive care units are reported.
