Obstructive sleep apnea hypopnea syndrome(OSAHS) is a clinical and critical disease to health, which the accuratly pathogenesis is not very explicit. The mainstream research suggested that dysfunction of upper airway dilator muscles is one of the hazard factors. Genioglossus innervated by the hypoglossal nerve plays crucial roles. It could expand volume of pharyngeal cavity, and increase airflow rate when stimulate it.With the development of anatomy and physiology, hypoglossal nerve stimulation(HGNS) entered into clinical trials, and had made tremendous progress since 2001...

Patients with nasal flow limitation and upper airway resistance syndrome (UARS) during sleep can present with low blood pressure and disturbing symptoms associated with hypervagotony. We hypothesized that the dynamic changes of the autonomic system related to inspiratory flow limitation can be quantified by the developed analytic technique applied on beat-to-beat heart rate (RR intervals) and finger photoplethysmography (PPG). METHOD: A breath-by-breath investigation based on the Hilbert-Huang transform was performed to explore autonomic nervous system changes observed during inspiratory flow limitation...

OBJECTIVE: Obstructive sleep apnea syndrome (OSAS) has been associated with elevated biochemical markers of inflammation. Although the exact mechanism is unknown, both sleep deprivation and hypoxemia are believed to be important causative factors. YKL-40, also known as chitinase-like protein, has been shown to be related to various inflammatory conditions including atherosclerosis, diabetes, cancer, and asthma. The present study aimed to evaluate the relationship between YKL-40 levels and the Apnea Hypopnea Index (AHI) in patients with obstructive sleep apnea syndrome...

BACKGROUND: Obstructive sleep apnea (OSA) is a common disorder estimated at 1-5% in the school-aged children. With the obesity prevalence reaching staggering rates globally, OSA in obese adolescents is estimated to be 4-5-folds higher than their lean peers. There is a paucity of data regarding obesity-related OSA in children 6 years and less. This is particularly relevant as OSA is associated with neurocognitive deficits. The aim of this study is to evaluate the prevalence of OSA among obese toddlers and preschool children and further to determine what other factors may be associated with the presence of OSA...

The reason for increased sleep disordered breathing with predominance of central apneas in the elderly is unknown. We hypothesized that the propensity to central apneas is increased in older adults, manifested by a reduced carbon-dioxide (CO2) reserve in older compared to young adults during non-REM (NREM) sleep. METHODS: 10 elderly and 15 young healthy adults underwent multiple brief trials of nasal noninvasive positive pressure ventilation during stable NREM sleep. Cessation of mechanical ventilation (MV) resulted in hypocapnic central apnea or hypopnea...

REVIEW
Steven H Feinsilver, Adam B Hernandez
Sleep normally changes with aging, with implications for healthy elderly individuals as well as for those with disease states. Less slow wave sleep (deep sleep) is expected, along with more awakenings, and a tendency toward earlier sleep times. Rapid eye movement sleep behavior disorder is seen primarily in elderly individuals, and it often represents the earliest sign of a chronic and progressive neurologic disease. Complaints of difficulty initiating and maintaining sleep (insomnia) become more common with aging...
