Exertional dyspnea, a key complaint of patients with chronic obstructive pulmonary disease
(COPD), ultimately reflects an increased inspiratory neural drive to breathe. In non …

Exertional dyspnea is present across the spectrum of chronic obstructive pulmonary disease
(COPD) severity. However, without realizing it themselves, patients may decrease daily …

There is well established evidence that the minute ventilation (V′ E)/carbon dioxide output
(V′ CO 2) relationship is relevant to a number of patient-related outcomes in COPD. In most …

In patients with chronic obstructive pulmonary disease (COPD), exertional dyspnoea
generally arises when there is imbalance between ventilatory demand and capacity, but the …

Patients with mild chronic obstructive pulmonary disease (COPD) and lower resting diffusing
capacity for carbon monoxide (DLCO) often report troublesome dyspnea during exercise …

Combining measurements of impaired lung mechanics (inspiratory constraints) with an
index of increased respiratory stimuli to metabolic demand (poor ventilatory efficiency) might …

Exertional dyspnoea is a cardinal symptom of patients with COPD [1]. Incremental
cardiopulmonary exercise testing (CPET), in particular, might provide useful mechanistic …

BACKGROUND Dyspnoea is a common and disabling symptom in patients with
cardiopulmonary disease. Unfortunately the mechanisms that produce dyspnoea are still …

To assess whether different indices of dyspnea can be obtained from cardiopulmonary
exercise test and whether these indices correlate with distinct physiological parameters in …

This paper is a post-hoc analysis of a previous study performed to investigate the
relationship between computerized tomography (CT) and lung function in 51 outpatients …
