The Effect of OSA on Severity and Prognosis of Patients With IgAN

The intervention in this study involves the use of Continuous Positive Airway Pressure (CPAP) treatment. Although the study is designed as an observational cohort study, where patients self-selected whether to receive treatment rather than being assigned, there is still an intervention project, CPAP, present in the observational cohort. CPAP is a commonly used therapy for obstructive sleep apnea (OSA) and other sleep-related breathing disorders. The principle of CPAP treatment lies in maintaining a constant airway pressure during sleep to prevent the collapse of the upper airway and ensure unobstructed breathing. The patient wears a mask connected to a CPAP machine, which generates a steady stream of air to provide the necessary pressure.
