Sleep apnea-hypopnea quantification by cardiovascular data analysis [PDF]
, 2014 Sleep apnea is the most common sleep disturbance and it is an important risk factor for cardiovascular disorders. Its detection relies on a polysomnography, a combination of diverse exams. In order to detect changes due to sleep disturbances such as sleep apnea occurrences, without the need of combined recordings, we mainly analyze systolic blood ...

Dynamics of Snoring Sounds and Its Connection with Obstructive Sleep Apnea [PDF]
, 2012 Snoring is extremely common in the general population and when irregular may indicate the presence of obstructive sleep apnea. We analyze the overnight sequence of wave packets --- the snore sound --- recorded during full polysomnography in patients referred to the sleep laboratory due to suspected obstructive sleep apnea. We hypothesize that irregular

Phenotype-based and Self-learning Inter-individual Sleep Apnea Screening with a Level IV Monitoring System [PDF]
arXiv, 2018 Purpose: We propose a phenotype-based artificial intelligence system that can self-learn and is accurate for screening purposes, and test it on a Level IV monitoring system. Methods: Based on the physiological knowledge, we hypothesize that the phenotype information will allow us to find subjects from a well-annotated database that share similar sleep ...

Both the Duration of Apnea and the Number of Apneas Are Important in Obstructive Sleep Apnea Syndrome [PDF]
Sleep Medicine Research, 2020 Apnea and hypopnea are generally considered to be equivalent in calculating the apnea-hypopnea index (AHI) regardless of their kind and duration.

Screening of Obstructive Sleep Apnea with Empirical Mode Decomposition of Pulse Oximetry [PDF]
, 2014 Detection of desaturations on the pulse oximetry signal is of great importance for the diagnosis of sleep apneas. Using the counting of desaturations, an index can be built to help in the diagnosis of severe cases of obstructive sleep apnea-hypopnea syndrome.

Sleep Disorders, 2012 More has been learned about sleep in the last 60 years than in the preceding 6000 years, to paraphrase one sleep researcher, and sleep apnea is an area in which knowledge growth has been particularly exponential. In the last several decades, sleep specialists have learned how to study sleep, subdividing it into stages based on the sleep-related changes

Cerebral Oxygenation during Apnea in Preterm Infants: Effects of Accompanying Peripheral Oxygen Desaturation [PDF]
Neonatal Medicine, 2021 Purpose Premature infants have immature respiratory control and cerebral autoregulation. We aimed to investigate changes in cerebral oxygenation during apnea with and without peripheral oxygen desaturation in premature infants.

Frontiers in Neuroscience, 2023 Periodic Cheyne–Stokes breathing (CSB) oscillating between apnea and crescendo–decrescendo hyperpnea is the most common central apnea. Currently, there is no proven therapy for CSB, probably because the fundamental pathophysiological question of how the ...

National Knowledge-Driven Management of Obstructive Sleep Apnea—The Swedish Approach
Diagnostics, 2023 Introduction: This paper describes the development of “Swedish Guidelines for OSA treatment” and the underlying managed care process. The Apnea Hypopnea Index (AHI) is traditionally used as a single parameter for obstructive sleep apnea (OSA) severity ...

Possibilities of diagnosing breathing disorders during sleep in home conditions
Diagnostyka, 2021 Disorders of breathing during sleep not only adversely affect the condition of the body during the daytime, but, above all, can be dangerous to health and life.
