Neuromuscular Fatigue During Exercise in COPD-HF Overlap (FIBOX)
Pulmonary Disease, Chronic Obstructive, Heart Failure
About this trial
This is an interventional treatment trial for Pulmonary Disease, Chronic Obstructive focused on measuring Exercise Tolerance, Hypoxia, Brain, Muscle Fatigue, Oxygen, Spectroscopy, Near-Infrared, Ultrasonography, Doppler, Transcranial

- Clinical stability for both diseases (COPD and/or HF) and no recent (within 3 months) exacerbation requiring a change in medications;
- Patient benefiting from health care coverage;
- Patient able to provide written informed consent.
Exclusion Criteria:
- Inability to perform cycle ergometry;

Patients with COPD
Patients with COPD-HF overlap
Patients with COPD will only exercise under medical air (for between-group comparison: COPD vs COPD-HF)
Patients with COPD-HF overlap will first exercise under medical air (for between-group comparison: COPD vs COPD-HF); Patients with COPD-HF overlap will then exercise under interventions (randomized order: non-invasive ventilation + medical air; non-invasive ventilation + hyperoxia, for within-group comparison: medical air vs intervention trials)
