An method and system for supplemental gas delivery that enables the identification of a need of therapeutic attention for patient receiving the supplemental gas ( 20 ) by detecting an onset of an exacerbation of a medical condition. Such a detection is performed by detecting audible events using a microphone ( 60 ) that is in fluid communication with a cannula ( 28 ) that is used to communicate the supplemental gas ( 20 ) with the airways of the patient ( 8 ). The audible event may be, for instance, a cough in the patient. A change in the relative frequency of coughs in the patient may be identified by the routines as being indicative of an onset of an exacerbation. |
