Background Pulmonary hypertension (PH) patients show, during exercise, an excessive
increase in ventilation (VE) compared to carbon dioxide output (VCO 2), determining a high …

Introduction Great ventilation to carbon dioxide output (Δ V˙ E/Δ V˙ CO 2) and reduced end-
tidal partial pressures for CO 2 (P et CO 2) during incremental exercise are hallmarks of …

Background Patients with primary pulmonary hypertension (PPH) have a pulmonary
vasculopathy that leads to exercise intolerance due to dyspnea and fatigue. To better …

Background Many patients with pulmonary arterial or chronic thromboembolic pulmonary
hypertension (PH) wish to travel to altitude or by airplane, but their risk of hypoxia-related …

Abstract Background and Objective Ventilatory inefficiency (high V′ E/V′ CO 2) and
resting hypocapnia are common in pulmonary vascular disease and are associated with …

Background and objective The responses of oxygen uptake efficiency (OUE) during
cardiopulmonary exercise training (CPET) have not been reported in patients with …

Background Arterial and thromboembolic pulmonary hypertension (PH) lead to arterial
hypoxaemia. Objective To investigate whether cerebral tissue oxygenation (CTO) in patients …

Objectives Primary pulmonary hypertension (PPH) is a pulmonary vasculopathy resulting in
exercise intolerance, usually due to dyspnea. We hypothesized that ventilation is increased …

Background Excessive exercise-induced hyperventilation and high prevalence of exercise
oscillatory breathing (EOB) are present in patients with post-capillary pulmonary …

Introduction The natural history of acute pulmonary embolism (PE) under treatment is about
a gradual resolution of the thrombi, and uncommonly, the development of chronic …
