This article presents a review of signals used for measuring physiology and activity during
sleep and techniques for extracting information from these signals. We examine both clinical …

The upper airway is the primary conduit for passage of air into the lungs. Its physiology has
been the subject of intensive study: both passive mechanical and active neural influences …

We have developed a low-cost, real-time sleep apnea monitoring system``Apnea
MedAssist” for recognizing obstructive sleep apnea episodes with a high degree of accuracy …

Sleep apnea is a common symptomatic disease affecting nearly 1 billion people around the
world. The gold standard approach for determining the severity of sleep apnea is full-night …

Electroencephalogram (EEG) is able to indicate states of mental activity ranging from
concentrated cognitive efforts to sleepiness. Such mental activity can be reflected by EEG …

Purpose To review available evidence in the literature on impulse oscillometry in the
assessment of lung function in children with respiratory diseases, especially asthma. Data …

The simple techniques generally used to investigate the biomechanical properties
associated with the respiratory process are able to identify only basic characteristics, just …

Objective Obstructive sleep apnea (OSA) causes a pause in airflow with reduced breathing
effort. In contrast, central sleep apnea (CSA) event is not accompanied with breathing effort …

Polysomnographic signals are usually recorded from patients exhibiting symptoms related to
sleep disorders such as obstructive sleep apnea (OSA). Analysis of polysomnographic data …

Obstructive sleep apnea (OSA) is a sleep disorder with long-term consequences. Long-term
effects include sleep related issues and cardiovascular diseases. OSA is often diagnosed …
