Design outcomes

Primary

MeasureTime frame
The rate of change in residual impedance during the first 5 minutes of quiet breathing after pursed-lip breathing compared to that during quiet breathing before pursed-lip breathing.;

Secondary

MeasureTime frame
the rate of change in residual impedance during the second 5-minute intervals of quiet breathing after pursed-lip breathing compared to that during quiet breathing before pursed-lip breathing;the rate of change in tidal impedance during the first 5-minute intervals of quiet breathing after pursed-lip breathing compared to that during quiet breathing before pursed-lip breathing;changes in the global inhomogeneity index (GI) during the first, second, and third 5-minute intervals of quiet breathing after pursed-lip breathing compared to those during quiet breathing before pursed-lip breathing;the rate of change in residual impedance during the third 5-minute intervals of quiet breathing after pursed-lip breathing compared to that during quiet breathing before pursed-lip breathing;the rate of change in tidal impedance during the second 5-minute interval of quiet breathing after pursed-lip breathing compared to that during quiet breathing before pursed-lip breathing;the rate of change in tidal impedance during the third 5-minute interval of quiet breathing after pursed-lip breathing compared to that during quiet breathing before pursed-lip breathing;changes in the center of ventilation (CoV) during quiet breathing after pursed-lip breathing compared to that during quiet breathing before pursed-lip breathing;
