From: Mechanical induction of cough in Idiopathic Pulmonary Fibrosis
Respiratory polygraphy recordings obtained from a subject with IPF demonstrating: a) Increased tidal volume on thoracic and abdominal effort belt recordings following initiation (arrow) of 60 Hz mechanical stimulation to the posterior lung base. b) Increased inspiratory effort on thoracic movement sensors preceding a single true three-phase cough (arrow) during 40 Hz mechanical chest wall stimulation to the posterior lung base.
