Results: The mean age of the cases was 55.07 with male frequency 58.9% and female 41.1%. Body mass index was 34.34, apnea hypopnea index 43.62, mean Arousal Index 30.64 and mean ESS was 12.83. There was significant relationship among ESS>10 with arousal index (p=0.009) and mean O2 saturation (p=0.029), But we didn’t detected correlation between ESS>10 with other polysomnographic parameters.
