Physics and Applications for Tracheal Sound Recordings in Sleep Disorders

Advances in technology have made it possible to reliably and not invasively record physiological parameters to diagnose sleep disorders. The most common sleep-related breathing disorder is sleep apnea. Complete cessation of airflow, apneas, or reduction of airflow, hypopneas occurs during sleep [1]. Based on the underlying pathophysiology, these respiratory events are classified as obstructive or central, with or without respiratory efforts. Accurate and reliable detection and classification of apneas and hypopneas are critical for the diagnosis and quantifying of the disease severity, morbidity, or mortality, as well as for appropriate therapy selection.
