Background: Determine predictors of early diagnosis and prevalence of OHS among patient with sleep disordered breathing (SDB) at Mansoura SDB unit. Aim of work: Determine predictors of early diagnosis and prevalence of OHS among patient with sleep disordered breathing (SDB) diagnosed at Mansoura SDB unit. Patients and methods: The study population consists of 212 patients referred to Mansoura University SDB unit for investigation of possible SDB. All patients were subjected to the following: Clinical evaluation, Pulse oximeter, Erect awake ABG, Spirometry and Polysomnography. Results: It was found that; The overall prevalence of OHS in studied cases was 13.2% (28 out of 212) and the prevalence of SDB in all studied cases was 83.02% (176 out of 212), 15.91% (28 out of 176) with OHS. The following predictors can be used for early diagnosis of OHS; a cutoff point of 93% of erect awake SpO2 with sensitivity of 97.1%, Specificity of 100%, p 28 mmol/L and AHI > 46.4.
