Dynamic hyperinflation during exercise
WebIntroduction. Dynamic lung hyperinflation (DLH) is an important factor involved in dyspnea on exertion and exercise intolerance in chronic obstructive pulmonary disease (COPD), and should be assessed in patients. 1,2 In COPD, both the decrease in lung elastic recoil pressure and narrowing of the peripheral bronchial lumen induce irreversible airflow … WebFeb 17, 2024 · Metronome-paced hyperventilation (MPH) is a simple applicable surrogate for exercise to detect dynamic hyperinflation. …

WebFeb 1, 2024 · BACKGROUND: Dynamic hyperinflation is a major cause of dyspnea in patients with COPD. Dynamic hyperinflation is usually measured with cardiopulmonary exercise testing, but this test requires maximal effort from the patient, and inspiratory capacity (IC) measurements may influence test results.

WebNov 30, 2012 · Dynamic hyperinflation has important clinical consequences in patients with chronic obstructive pulmonary disease (COPD). Given that most of these patients have respiratory and peripheral muscle weakness, dyspnea and functional exercise capacity may improve as a result of inspiratory muscle training (IMT).
