Abstract
We used a questionnaire to study sleep apnea syndrome (SAS) in 53 patients (46 males and 7 females) who were referred to our hospital complaining of sleeping disturbance, then the relationship between questionnaire-rated SAS score and factors, such as sex, age and obesity, and Epworth sleepiness scale was investigated. Overnight changes in questionnaire ratings and in the degree of apnea as examined using polysonography (PSG) and SpO2 were recorded. There was a statistically significant correlation between apnea-hypopnea index and SAS score, whereas there was no significant correlation between SpO2 level and SAS score. We conclude that our questionnaire can be used to diagnose SAS.
