Cumulative Cough Frequency
cough, coughs, cough airflow, Cough airflow

Representative cough airflow waveform. Digitized airflow waveform depicting real-time respiratory patterns of a cough. Cough airflow parameters are displayed during the inspiratory, compression, and expiratory phases.More coughs are generated with higher concentrations of inhaled ethyl butyrate. Data are represented with box plots, in which the thickest horizontal lines display median cumulative cough frequency (Psychophysical evaluation and total number of coughs produced across inhaled ethyl butyrate concentrations before and after breath control implementation for participants assigned to pursed-lip breathing (PLB) and slow-paced breathing (SPB).
