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

Although this study is designed as an observational cohort study, where patients were not assigned to intervention or non-intervention groups, there is still an intervention project indicator present in the observational cohort. The intervention in this study involves the use of Continuous Positive Airway Pressure (CPAP) treatment. 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.
