Revitalizing respiration: A comprehensive review of oxygen therapy in interstitial lung diseases

Interstitial Lung Diseases (ILDs) encompass a diverse group of disorders characterised by inflammation and fibrosis, leading to significant impairment in lung function and quality of life. With the increasing prevalence of ILDs, managing these conditions has become a pressing medical and economic challenge. Oxygen therapy is crucial in ILD management, offering benefits beyond hypoxemia correction, including symptom relief and potential influence on disease progression. However, patient compliance, long-term use, side effects, and the psychosocial impact of therapy present ongoing challenges. This narrative review examines the critical role of oxygen therapy in ILDs, highlighting its current applications, associated challenges, and emerging innovations such as targeted therapies, personalized oxygen delivery, and advancements in technology that promise to enhance patient care in this complex field.
