|Sleep Apnea Syndromes Snoring|
The purpose of this study is to evaluate the feasibility of assessing breathing problems during sleep with minimally obtrusive sensors (a bedside microphone and wireless pulse oximeter worn on the fingertip). The investigators will use the data collected with these sensors to develop algorithms for automatically detecting sleep apnea events. Subjects will be asked to place unobtrusive sensors (bedside microphone and wireless pulse oximeter) in their home sleep environment. The subjects will start the at-home data collection before they fall asleep, and stop the data collection the next morning when they wake. The subjects will then return the sensors to the investigator for analysis.
We are looking for people interested in participating in the at-home portion of our study. We will only collect at-home data for one night of sleep per subject. After this one night, no further data collection or monitoring will occur. Subjects will be compensated for their time.
A standard sleep-breathing questionnaire (the "Berlin Questionnaire") will be administered. This questionnaire is widely used as a screening tool to determine if a person may have disordered breathing during sleep. This questionnaire consists of 10 multiple-choice questions related to snoring, daytime sleepiness, and other related conditions.

Overnight sleep at home (30 subjects)
Overnight sleep at the OHSU sleep lab during routine polysomnography (30 subjects)

- Non-typical breathing sounds or patterns correspond to oxygen desaturation [ Time Frame: On the day of the study only (1 day) ]This study aims to see if it is feasible to assess breathing problems during sleep using a high-quality microphone and wireless pulse oximeter. Our primary objective is to determine if non-typical breathing sounds or patterns correspond to oxygen desaturations of 3% or more from baseline.
