Background: The present study validates and evaluates the sensitivity and specificity of four internationally popular questionnaires, translated into Chinese, for assessing suspected obstructive sleep apnea (OSA) patients, namely, the Berlin questionnaire, the ASA checklist, the STOP questionnaire and the STOP-BANG questionnaire. Their predictive values in OSA risks in patients presenting with OSA symptoms are examined. Questionnaires may be helpful in prioritizing polysomnography (PSG) and in treatment for the more severe cases.

Article Synopsis
- The study assesses consciousness levels during sedation endoscopy using bispectral analysis in patients with obstructive sleep apnea.
- Midazolam sedation resulted in mostly lighter sleep stages (N1 and N2), with minimal deep sleep (N3) and no REM sleep detected, indicating ineffective sedation for deeper analysis.
- The research concludes that sleep endoscopy is a valuable tool for evaluating upper airway dynamics to improve surgical planning for these patients.
