Relationship between obstructive sleep apnea severity and sleep, depression and anxiety symptoms in newly-diagnosed patients. [PDF]
PLoS ONE, 2010 Obstructive sleep apnea (OSA) occurs in at least 10% of the population, and leads to higher morbidity and mortality; however, relationships between OSA severity and sleep or psychological symptoms are unclear.

An Effective Method for Distinguishing Sleep Apnea and Hypopnea Based on ECG Signals [PDF]
IEEE Access, 2021 Good sleep quality is essential to our life and work. The two major challenges in evaluating sleep quality are the scoring of sleep stages and sleep apnea detection. In addition to sleep apnea, hypopnea is also a respiratory event that occurs at an equal

Cerebral oxygenation responses to obstructive sleep apnea in cognitively normal older adults: a study using simultaneous polysomnography and functional near-infrared spectroscopy [PDF]
Scientific ReportsObstructive sleep apnea (OSA) can cause intermittent cerebral hypoxia that may impair brain health. However, widely used clinical indicators such as the Apnea-Hypopnea Index (AHI) and peripheral oxygen saturation (SpO₂) may not accurately capture ...

Hypopnea definitions, determinants and dilemmas: a focused review
Sleep Science and Practice, 2018 Obstructive sleep apnea (OSA) is defined by the presence of repetitive obstructive apneas and hypopneas during sleep. While apneas are clearly defined as cessation of flow, controversy has plagued the many definitions of hypopneas, which have used ...

Consumer personas for CPAP purchasing in older adults with obstructive sleep apnea: a hospital database study [PDF]
Future Science OAIntroduction Even though a continuous positive airway pressure machine (CPAP) is effective in obstructive sleep apnea in older adults, there is limited data on predictors of CPAP purchasing in older adults with OSA.

Detecting Sleep-Related Breathing Disorders Using FMCW Radar [PDF]
Journal of Electromagnetic Engineering and Science, 2023 Polysomnography (PSG) is currently the sole method for detecting breathing disorders that occur during sleep, such as apnea and hypopnea. However, PSG monitoring is quite inconvenient for test subjects.
