Assessment of PPG & PAT to Detect Upper Airway Obstruction in Patients With Obstructive Sleep Apnea

Not Applicable

• Conditions: Sleep Apnea, Obstructive

• Registration Number: NCT01831583
• Lead Sponsor: Sotera Wireless, Inc.

Brief Summary

The goal of this study is to collect raw waveform data for two separate noninvasive methods, both of which may be useful for the assessment of upper airway obstruction.
