Noncontact Detection of Sleep Apnea Using Radar and Expectation-Maximization Algorithm [PDF]

arXiv, 2023
Sleep apnea syndrome requires early diagnosis because this syndrome can lead to a variety of health problems. If sleep apnea events can be detected in a noncontact manner using radar, we can then avoid the discomfort caused by the contact-type sensors that are used in conventional polysomnography.

A Dual‐Modal Wearable Pulse Detection System Integrated with Deep Learning for High‐Accuracy and Low‐Power Sleep Apnea Monitoring

Advanced Science, EarlyView.
A dual‐modal wearable pulse detection system is developed for sleep apnea monitoring by integrating a self‐powered PENG and PPG sensor with a biomimetic fingertip structure. Through a two‐stage detection strategy, continuous PPW monitoring and on‐demand PPG detection achieve high‐accuracy sleep apnea recognition while maintaining low power consumption.

Sleep Apnea and Respiratory Anomaly Detection from a Wearable Band and Oxygen Saturation [PDF]

arXiv, 2021
Objective: Sleep related respiratory abnormalities are typically detected using polysomnography. There is a need in general medicine and critical care for a more convenient method to automatically detect sleep apnea from a simple, easy-to-wear device.

Respiratory and cardiac monitoring at night using a wrist wearable optical system [PDF]

40th International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC 2018), 2017
Sleep monitoring provides valuable insights into the general health of an individual and helps in the diagnostic of sleep-derived illnesses. Polysomnography, is considered the gold standard for such task. However, it is very unwieldy and therefore not suitable for long-term analysis.

Children With 22.Q.11.2 Deletion Syndrome: Sleep‐Disordered Breathing and Management

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Patients with 22q11.2 deletion syndrome (22q11DS) are predisposed to obstructive sleep apnea (OSA) due to an abnormal craniofacial anatomy with pharyngeal hypotonia, retrognathia, micrognathia, and glossoptosis. The aim of the study was to describe the prevalence and management of OSA in a cohort of children with 22q11DS.

Automated Respiratory Event Detection Using Deep Neural Networks [PDF]

arXiv, 2021
The gold standard to assess respiration during sleep is polysomnography; a technique that is burdensome, expensive (both in analysis time and measurement costs), and difficult to repeat. Automation of respiratory analysis can improve test efficiency and enable accessible implementation opportunities worldwide.

Cyclic Alternating Pattern Dynamics in Individuals at Risk for Developing Parkinson's Disease

Annals of Neurology, EarlyView.
Objective The objective of this study was to investigate the differences in cyclic alternating patterns (CAP) metrics, a non‐rapid eye movement (NREM) sleep physiological rhythm, among recently diagnosed patients with Parkinson's disease (PD), and individuals at high and low risk for developing PD based on genetic and prodromal risk.
