Correlation of Endoscopic View of Airway Obstruction With RRa Signal in OSA Patients Under Dexmedetomidine Anesthesia Monitored With SedLine EEG
Patients with obstructive sleep apnea (OSA) could have several anatomical causes of
obstruction. A sleep endoscopy study is a technique to help determine the anatomical cause of
OSA. This study will be using standard of care practice and infuse dexmedetomidine (DEX) to
induce sleep. The goals of the study are to (1) confirm airway obstruction with endoscopic
view and correlate that with Acoustic Respiratory Rate (RRa) signal at the moment of airway
obstruction, and (2) characterize the EEG signals when subjects are under DEX sedation alone.

Inclusion Criteria:
- Adult patients more than 18 years old with American Society of Anesthesiologists (ASA)
classification of I, II, or III.
- Patients undergoing sedation for sleep endoscopy with DEX alone, and possible surgical
follow-up.
Exclusion Criteria:
- ASA classification higher than III.
- Any deformities or diseases that may prevent application of SedLine (Masimo Sedation
Monitoring) or RAM (Masimo Rainbow Acoustic Monitoring) sensors with a proper fit
- Inability to obtain any physiological, vital, demographics and real time anaesthesia
data
- Subjects who have known intolerance to any of the drugs to be used according to the
study protocol
- Subjects deemed not suitable for study at the discretion of the Principal
Investigator.
