snore loudly, and as she could not be roused, the door was forced, and the girl was found lying flat on the floor quite insensible, her breathing stertorous, eyes semi-closed, jaws locked, features distorted, and a stream of bloody froth running out from both the angles of the mouth, her muscles rigid, her dress saturated with urine, voided involuntarily, with violent convulsions occurring almo...

We established and tested a snoring detection method using a polyvinylidene fluoride (PVDF) sensor for accurate, fast, and motion-artifact-robust monitoring of snoring events during sleep. Twenty patients with obstructive sleep apnea participated in this study. The PVDF sensor was located between a mattress cover and mattress, and the patients' snoring signals were unconstrainedly measured with...

BACKGROUND Snorers often experience symptoms of sleep disordered breathing (SDB) which is largely undiagnosed in the population. Information on SDB experiences is needed to target high-risk individuals that may benefit from treatment of snoring. OBJECTIVE This study compares the experience of the nighttime and daytime symptoms of SDB of habitual snorers with that of non-habitually snoring adu...

STUDY OBJECTIVE To determine whether nasal oxygen therapy at 2 L/min would (1) reverse nocturnal hypoxemia and (2) improve neuropsychologic function in men who snore heavily. DESIGN To select heavy-snoring subjects for a treatment protocol, volunteers were screened for one night, breathing air the first half and oxygen the second half of the night. If nocturnal oxygen desaturation occurred in...

background and objective : obstructive sleep apnea (osa) syndrome is a kind of sleep-related disorder with complex features and may lead to daytime sleepiness. this study aimed to find the differences between smokers and non-smokers regarding the parameters of polysomnography. materials and methods : this was a cross-sectional study conducted on consecutive patients referred to a sleep lab to p...

Sleep disorder breathing is characterized by repetitive upper airway obstruction and consequent oxyhaemoglobin desaturation during the deeper stages of sleep. The disorder is due to combination of both abnormal upper airway anatomy and yet to be determined afferent/efferent somatosensory loop. Apnea is defined as a cessation of airflow (breathing) lasting for at least 10 seconds. Hypo-apnea is ...

A new method to detect snoring episodes in sleep sound recordings is proposed. Sleep sound segments (i.e., 'sound episodes' or simply 'episodes') are classified as snores and nonsnores according to their subband energy distributions. The similarity of inter- and intra-individual spectral energy distributions motivated the representation of the feature vectors in a lower dimensional space. Episo...

UNLABELLED Few studies in the literature have looked into the cardiovascular and metabolic effects of Obstructive Sleep Apnea Syndrome (OSAS) in children. OBJECTIVE This study aims to evaluate the metabolic profile of non-obese children with OSAS. METHODS Fifty-two children were enrolled in this study, 21 girls and 31 boys. Patients were divided into two groups: OSAS (28 children) and Snore...

Chronic pain due to osteoarthritis (OA) can lead to significant disruption of sleep and increased restlessness. Our objective was to assess whether naturally occurring canine OA is associated with nighttime restlessness and so has potential as a model of OA-associated sleep disturbance. The study was designed as a two-part prospective masked, placebo-controlled study using client-owned dogs (Pa...
