1. A computer implemented method for operating a respiratory ventilator ventilating a subject comprising:
- (a) obtaining one or more body signals from the subject indicative of the subject'"'"'s ventilation;
(b) analyzing the one or more signals so as to perform a spirometric assessment of the ventilation; and
(c) determining whether the spirometric assessment satisfactorily conforms to one or more predetermined spirometric standardswherein the spirometric standard is obtained by determining a total acoustic energy on a body surface overlying the subject'"'"'s respiratory tract.

Abstract
A system and computer implemented method for operating a respiratory ventilator ventilating a subject. One or more body signals obtained from the subject indicative of the subject'"'"'s ventilation are analyzed so as to perform a spirometric assessment of the ventilation. It is then determined whether the spirometric assessment satisfactorily conforms to one or more predetermined spirometric standards. If the spirometric assessment does not satisfactorily conform to the spirometric standard, the operating parameters of the ventilator are adjusted. The invention also provides a system for carrying out the method.
