Background: Sleep being an essential biological function, has a significant role. The basic structure of sleep consists of non-rapid eye movement (NREM) and rapid eye movement (REM). Obstructive sleep apnea-hypopnea syndrome (OSAHS) is the commonest of sleep-related breathing disorders, which is a chronic disorder characterized by the presence of partial or complete blockage of the upper airway causing reduced (hypopnea) or absent (apnea) airflow during sleep. Continuous positive airway pressure (CPAP) therapy reduces OSA severity, improves both daytime and nocturnal symptoms in particular excessive daytime sleepiness and fatigue. Objective: Assessment of AHI, Arousal Index, and sleep pattern improvement (N1, N2, N3, and R duration), blood pressure pre and post CPAP therapy and compliance of patients to CPAP therapy over a period of ≥6 months Methodology: A total 107 polysomnography (PSG) reports of patients who visited the sleep centre from March 2019 to March 2020 were included for the analysis. Results: Our study reported a significant decrease (p<0.0001) in AHI, Arousal Index, and blood pressure post CPAP therapy in the overall population, both the genders and in all age groups. There was a significant increase in N3, and R (p<0.05) post CPAP therapy in most of the patients, whereas there was a marginal decrease in N1 and N2 post CPAP therapy. Conclusion: Our results from the real-life clinical setting confirms that CPAP is effective at decreasing AHI, Arousal Index, blood pressure, and adherence to treatment with CPAP reported increased sleep efficiency and improvement in both nocturnal and diurnal symptoms in Indian patients with moderate to severe OSA.Keywords
