Nasal High-flow Oxygen Therapy During Rehabilitive Exercise Training in ILD (PID-OX)
2026年6月25日 更新者：Frédéric Hérengt
Does Nasal High-Flow Oxygen Potentiate the Effects of Rehabilitative Exercise Training in Chronic Fibrotic Interstitial Lung Disease?
Although uncommon, interstitial lung diseases (ILDs), and particularly idiopathic pulmonary fibrosis (IPF), are progressive, irreversible, and ultimately fatal without treatment. Pharmacological therapies can slow the decline in forced vital capacity (FVC) and six-minute walk distance (6MWD), but they do not improve exercise-related respiratory limitations or quality of life.
Therefore, pulmonary rehabilitation (PR) is recommended for patients with a confirmed diagnosis of ILD/IPF who experience exercise limitation and significant functional impairment. However, the benefits of PR remain modest, and the optimal rehabilitation strategies for these patients have yet to be defined, particularly given the severe dyspnea and often profound exertional hypoxemia that characterize the disease.
To optimize the effects of PR, especially exercise training, the use of high-flow nasal oxygen (HFNO) during exercise has been proposed in certain respiratory conditions such as chronic obstructive pulmonary disease (COPD). By improving oxygenation and exercise tolerance, HFNO applied during exercise training sessions may enhance the effectiveness of pulmonary rehabilitation.
