Abstract

A system for measuring the mechanical impedance of a patient's respiratory system during spontaneous respiratory activity characterised in that it comprises a fan, a motor driving said fan; said motor and said fan are placed inside a cavity; said cavity is divided into two sub-cavities separated from each other so as to prevent the passage of air, one containing the motor and the other containing the fan and comprising an initial end and a terminal end, both of which have access to the outside.

Abstract

A method for the early identification of recurrences of chronic obstructive pulmonary disease comprising the following steps of; measuring, with a predefined time frequency, a plurality of parameters that define the pulmonary function of a patient by means of the forced oscillation technique (FOT); calculating the trend of said plurality of parameters in a predefined time period; identifying an impending recurrence by comparing the parameters describing said trend of said plurality of parameters with predefined thresholds; where the step of calculating the trend of said plurality of parameters is achieved by calculation of an N order polynomial regression model; and the step of identifying an impending recurrence by comparing said parameters describing said trend with predefined thresholds comprises the step of comparing at least one coefficient of the N order polynomial regression with predefined thresholds.
