Method and System for Assessing Lung Condition and Managing Mechanical Respiratory Ventilation
First Claim
1. A method for use in monitoring the respiratory system of a subject, the method comprising:
- (a) recording one or more signals from the subject, the signal varying in time according to operation of the respiratory system; and
;
(b) processing the recorded signals to obtain a predetermined functional thereof presenting one or more time-varying energy functions of the subject, an abnormality in said one or more energy functions being indicative of a suspected abnormality in the operation of the respiratory system.

Abstract
The present invention discloses a novel non-invasive, bedside system and method to monitor parameters associated lung changes. A novel approach for monitoring the operation of the respiratory system of a subject is provided. There is also provided a method for objectively evaluating the benefit of one mode of ventilation over another, and for assessing the differences in regional lung vibration during different modes of mechanical ventilation. The method comprises recording one or more signals from the subject, the signal varying in time according to operation of the respiratory system; and; processing the recorded signals to obtain a predetermined functional thereof presenting one or more time-varying energy functions of the subject, an abnormality in the one or more energy functions being indicative of a suspected abnormality in the operation of the respiratory system. The signals may be acoustic signals recorded by a plurality of acoustic sensors placed over the subject'"'"'s thorax or back, and the at least one time-varying energy function is obtained from one or more specific regions of lung or by summing/averaging the time-dependent acoustic signals of the plurality of sensors indicative of the whole lungs.
