Assessing respiratory mechanics and muscle function is critical for both clinical practice and
research purposes. Several methodological developments over the past two decades have …

The purpose of this study was to compare the mechanics of breathing including the measurement
of expiratory flow limitation, end‐expiratory lung volume, end‐inspiratory lung volume, …

We hypothesized that inspiratory muscle training (IMT) would attenuate the sympathetically
mediated heart rate (HR) and mean arterial pressure (MAP) increases normally observed …

To minimize transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2),
the novel coronavirus responsible for coronavirus disease (COVID-19), the US Centers for …

Rationale: Several studies in mild chronic obstructive pulmonary disease (COPD) have
shown a higher than normal ventilatory equivalent for carbon dioxide ( V . e/ V . co 2 ) during …

The purpose of this study was to examine the physiological mechanisms of persistent dyspnoea
in COVID-19 survivors. Non-critical patients (n = 186) with varying degrees of COVID-19 …

Chronic obstructive pulmonary disease (COPD) is a preventable and treatable lung disease
characterized by airflow limitation that is not fully reversible. In a significant proportion of …

Cardiopulmonary exercise testing (CPET) is an established method for evaluating dyspnea
and ventilatory abnormalities. Ventilatory reserve is typically assessed as the ratio of peak …

Background To better understand the interrelationships among disease severity, inspiratory
capacity (IC), breathing pattern, and dyspnea, we studied responses to symptom-limited …

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 presence or …
