System and method for the automatic evaluation of the indexes of volemic status

摘要

The present invention refers to a system and a method for the automatic evaluation of the indexes of volemic status (Systolic Pressure Variation or SPV) in patients submitted to mechanic ventilation, starting form the analysis of the variations of the values of blood pressure. In one embodiment the system for the automatic evaluation of indexes of volemic status of a patient (1) comprises: means (7) suitable for submitting said patient to a preset period of apnoea and to a preset period of mechanical breathing; heart pressure probes (2) for acquiring an analogical signal relative to the values of the blood pressure of said patient in said preset periods; an analogue/digital converter (3) for the conversion of said analogical signals into a digital signal; means (5) for determining the values of positive systolic peaks of said pressure; means (5) for calculating first and second indexes of volemic status; a display (6) of said indexes of volemic status. <IMAGE>
