Classification: A61B,A61M

Abstract:
System for the automatic evaluation of indexes of volemic status of a patient comprising:means suitable for submitting said patient to a preset period of apnoea and to a preset period of mechanical breathing; probes of heart pressure for acquiring an analogical signal relative to the values of the blood pressure of said patient in said preset periods; an analogue/digital converter for the conversion of said analogical signal into a digital signal; means to determine the values of positive systolic peaks of said pressure; means to determine a first average value of the positive systolic peaks of said pressure in said preset period of apnoea; means to determine a second average value of the maximum positive systolic peaks of said pressure in said preset period of mechanical breathing; means to determine a third average value of the minimum positive systolic peaks of said pressure in said preset period of mechanical breathing; means to calculate a first index of volemic status equal to the difference between said second value and said first value; means to calculate a second index of volemic status equal to the difference between said third value e said first value; a display of said indexes of volemic status.
