In COPD, dynamic hyperinflation (DH) occurs during exercise and during metronome-paced
tachypnea (MPT). We investigated the relationship of DH with breathing pattern and …

Dynamic hyperinflation (DH) during exercise is associated with both dyspnea and exercise
limitation in COPD. Metronome-paced tachypnoea (MPT) is a simple alternative for studying …

Background: Dynamic hyperinflation due to increased respiratory frequency during exercise
is associated with limitations in exercise capacity in patients with moderately severe chronic …

In contrast to the decline in FEV1, the behavior of dynamic hyperinflation (DH) over time is
unknown in patients with COPD. Metronome-paced hyperventilation (MPH) is a simple …

Dynamic hyperinflation (DH) during exercise occurs in most but not all patients with
advanced chronic obstructive pulmonary disease (COPD). It is not known whether the …

Study objective: To detect dynamic hyperinflation by comparing reduction in inspiratory
capacity (IC) during both paced hyperventilation and cycle ergometry in patients with …

Background: Identification of patients with chronic obstructive pulmonary disease (COPD)
who develop dynamic hyperinflation (DH) during activities in daily life (ADL) is important …

In COPD patients, tachypnea should increase (dynamic) hyperinflation by shortening
expiratory time. We developed a method to evaluate the time course and degree of dynamic …

Approximately 20% of chronic obstructive pulmonary disease (COPD) patients have been
considered to have a “nonhyperinflator phenotype.” However, this judgment depends on …

Introduction This prospective study was carried out to investigate if metronome‐paced
tachypnea (MPT) can serve as an accurate diagnostic tool to identify patients with chronic …
