Purpose To evaluate the degree of lung hyperinflation (LH) in patients with stable chronic
obstructive pulmonary disease (COPD) by lung ultrasound score (LUS) and assess its value …

Purpose Lung hyperinflation is a feature of chronic obstructive pulmonary disease (COPD)
and can determine pivotal consequence on symptoms, exercise tolerance and quality of life …

The prognostic role of resting pulmonary hyperinflation as measured by residual volume
(RV)/total lung capacity (TLC) in chronic obstructive pulmonary disease (COPD) remains …

Background It is unknown whether aggressive medication strategies should be used for
early COPD with or without lung hyperinflation. We aimed to explore the characteristics and …

Purpose COPD is characterized by an accelerated and progressive decline in forced
expiratory volume in 1 second (FEV1) and lung hyperinflation. Although lung hyperinflation …

Objective This study was performed to determine the usefulness of a newly developed
spirometer for the quantitative assessment of dynamic lung hyperinflation (DLH) following …

Purpose To compare ultrasound measurements of diaphragmatic mobility, diaphragm
thickness, and diaphragm thickening fraction with one another and also with lung function …

Purpose Heart failure (HF) often coexists with chronic obstructive pulmonary disease
(COPD) and is associated with worse outcomes. We aimed to assess the feasibility of …

Lung hyperinflation is a consequence of airway obstruction, increased airway resistance
and compliance in patients with chronic obstructive pulmonary disease (COPD) which may …

Background Although the pathophysiological mechanisms involved in the development of
dyspnoea and poor exercise tolerance in patients with COPD are complex, dynamic lung …
