A Clinical Evaluation of a Low-Cost Strain Gauge Respiration Belt and Machine Learning to Detect Sleep Apnea [PDF]
arXiv, 2021 Sleep apnea is a serious and severely under-diagnosed sleep-related respiration disorder characterized by repeated disrupted breathing events during sleep. It is diagnosed via polysomnography which is an expensive test conducted in a sleep lab requiring sleep experts to manually score the recorded data.

Automatic scoring of apnea and hypopnea events using blood oxygen saturation signals [PDF]
arXiv, 2020 The obstructive sleep apnea-hypopnea (OSAH) syndrome is a very common and frequently undiagnosed sleep disorder. It is characterized by repeated events of partial (hypopnea) or total (apnea) obstruction of the upper airway while sleeping. This study makes use of a previously developed method called DAS-KSVD for multiclass structured dictionary learning

Central actions of somatostatin in the generation and control of breathing
Biological Research, 2005 The neuropeptide somatostatin is involved in many functions in the central nervous system as well as in the periphery. When it is centrally injected, an irreversible apnea is often developed.

Jornal de Pediatria, 2001 OBJECTIVE: To review medical literature related to apnea of prematurity. SOURCES: Extensive literature search and clinical practice-oriented concepts. SUMMARY OF THE FINDINGS: Apnea is one of the most common respiratory disorders in the neonatal period. Immaturity of the central nervous system is associated with instability of respiration.

Quantification of Sleep Fragmentation Through the Analysis of Sleep-Stage Transitions [PDF]
arXiv, 2003 We introduce new quantitative approaches to study sleep-stage transitions with the goal of addressing the two following questions: (i) Can the new approaches provide more information on the structure of sleep-stage transitions? (ii) How does sleep fragmentation in patients with sleep apnea affect the structure of sleep-stage transitions?

Reproduction of hypopnea phenomenon using a physical and numerical model [PDF]
Proceedings of the 6th International Symposium on Computer Methods
in Biomechanics & Biomedical Engineering FIRST Numerics Ltd, ISBN
0-9549670-0-3 (Ed.) (2004) 1-6, 2006 Obstructive sleep apnea syndrome is now considered as a major health care topic. An in-vitro setup which reproduces and simplifies upper airway geometry has been the basis to study the fluid/walls interaction that leads to an apnea. It consists of a rigid pipe (the pharynx) in contact with a deformable latex cylinder filled with water (the tongue). Air

Interfering with sleep apnea [PDF]
Bioelectronic MedicineAbstractThe effects of electromagnetic interference have been hiding in plain sight for millennia and are now being applied to the non-invasive stimulation of deep tissues. In the article by Missey et al., the effect of non-invasive stimulation of the hypoglossal nerve by an interference envelope of interfering carrier waves is examined in mice and ...

Effects of early aminophylline therapy on clinical outcomes in premature infants
Pediatrics and Neonatology, 2023 Background: Aminophylline use and the association between clinical outcomes and therapy timing have been less investigated. The objective of this study was to determine the efficacy of early aminophylline use (within the first two days of life) in ...
