Respiratory-swallowing coordination in normal subjects: Lung volume at swallowing initiation

Highlights • Lung volume at swallowing initiation in normal subjects is described. • Swallowing is superimposed on the quiet breathing respiratory cycle. • Swallowing occurs from mid tidal to resting expiratory lung volume levels. • Effects of bolus type, task and instructions were observed. • Swall...

Zusammenfassung:	Highlights • Lung volume at swallowing initiation in normal subjects is described. • Swallowing is superimposed on the quiet breathing respiratory cycle. • Swallowing occurs from mid tidal to resting expiratory lung volume levels. • Effects of bolus type, task and instructions were observed. • Swallowing at mid to low lung volumes is advantageous for airway protection.
