Patients with chronic obstructive pulmonary disease (COPD) have slowed pulmonary O 2
uptake (V̇o 2 p ) kinetics during exercise, which may stem from inadequate muscle O 2 …

BACKGROUND: Delayed postexercise heart rate recovery (HRR) has been associated with
disability and poor prognosis in chronic cardiopulmonary diseases. The usefulness of HRR …

Chronic hypersensitivity pneumonitis is a common fibrotic interstitial lung disease. The
prevalence of pulmonary hypertension diagnosed by right heart catheterisation and its …

Pulmonary arterial hypertension is an incurable disease marked by dysregulated metabolism,
both at the cellular level in the pulmonary vasculature, and at the whole-body level …

Background Increased ventilatory ( V · E) response to carbon dioxide output ( V · CO 2 ) is a
key finding of incremental cardiopulmonary exercise testing in both heart failure and …

Background: The rate of change (Δ) in cerebral oxygenation (COx) during exercise is
influenced by blood flow and arterial O 2 content (CaO 2 ). It is currently unclear whether ΔCOx …

Introduction: Coronavirus disease 2019 (COVID-19) is still increasing worldwide, and as a
result, the number of patients with pulmonary fibrosis secondary to COVID-19 will expand …

The prevailing view is that exertional dyspnoea in patients with combined idiopathic pulmonary
fibrosis (IPF) and emphysema (CPFE) can be largely explained by severe hypoxaemia. …

Inspiratory pressure support (IPS) plus positive end-expiratory pressure (PEEP) ventilation
might potentially interfere with the “central” hemodynamic adjustments to exercise in patients …
