Study Details

Brief summary:

The purpose of this study is to investigate the feasibility of sound analysis for: a) sleep apnea detection both during wakefulness and sleep, and b) flow-sound relationship during both wakefulness and sleep in patients and control individuals. The ultimate goal of our research is to simplify the current assessments for sleep apnea detection so that it is more convenient for patients and also much faster than the current techniques.

OSA Participants

Inclusion Criteria: 1) age between 18 to 70 years; 2) suspected of OSA and referred to full PSG study by a doctor.

Exclusion Criteria: 1) being diagnosed with a chronic respiratory disease including pulmonary fibrosis, emphysema, respiratory infectious disease, nocturnal asthma, obstructive pulmonary lung disease, pulmonary hypertension, congestive heart failure, sleep related hypoventilation and neuromuscular disorders; 2) having insomnia or restless leg; 3) drug addiction; and 4) under the current, direct supervision of the PI of this study.

Healthy Controls

Inclusion Criteria: 1) age between 18 to 70 years; 2) non-snorer, and being free of any sleep disorders.

Exclusion Criteria: same as the OSA Participants. All participants must not have any cold or any other respiratory illness at the time of recording.

Illiterate participants may still participate in the study; however, there must be a witness who is not involved in the study (i.e. PI, Co-PI, study coordinator, research assistants (RA)/students, etc.) present to witness the consent process between the participant and the individual obtaining consent.
