Negative Oxygen Ion Therapy for Coal Workers' Pneumoconiosis

Abstract China is a major coal-producing country, and coal worker pneumoconiosis (CWP) is the most prevalent and severe occupational disease annually. As the disease progresses, patients experience varying degrees of lung damage for which there is no effective treatment. Even after symptomatic treatment, issues such as poor respiratory function and sleep quality persist. This study focused on CWP patients who were administered artificial negative oxygen ion therapy to analyze changes in lung function, serum cytokine levels, and sleep quality before the intervention and at 1 month and 3 months postintervention. Our aim was to investigate the impact of artificial negative oxygen ions on the respiratory function and sleep quality of CWP patients.
