Cough epochs can be characterized using airflow and oblique surface EMG activity. Airflow and integrated sEMG traces (∫) from the oblique muscle were measured during cough epochs (inspiratory phase followed by multiple expiratory efforts). The dotted lines represent phases and components of each cough epoch measured: Inspiratory phase duration (IPD) (A to C); inspiratory phase peak flow (IPPF) (B); inspiratory phase rise time (IPRT) (A-B); compression phase duration (CPD) (C to D) particularity an inspiratory to expiration compression phase; expiratory phase rise time (EPRT) (D to E); expiratory phase peak flow (EPPF) (E); and expiratory to expiratory CPD (F to G).
