Determinants of dynamic hyperinflation during metronome-paced tachypnea in COPD and normal subjects
CB Cooper, GL Calligaro, MM Quinn… - Respiratory Physiology …, 2014 - Elsevier
In COPD, dynamic hyperinflation (DH) occurs during exercise and during metronome-paced
tachypnea (MPT). We investigated the relationship of DH with breathing pattern and …

Time course and degree of hyperinflation with metronome-paced tachypnea in COPD patients
SS Weigt, M Abrazado, EC Kleerup… - COPD: Journal of …, 2008 - Taylor & Francis
