Cardiovascular Variability and Heart Rate Response Associated With Obstructive Sleep Apnea

Obstructive sleep apnea is often associated with microarousals and a stimulation of the sympathetic nervous system. The knowledge of this autonomic activation may help understanding the in...

Vasoactive Hormones and Oxygen Saturation During Apneic Events in Patients With Obstructive Sleep Apnea

The mechanisms involved in development and maintenance of hypertension in obstructive sleep apnea are not clarified. We hypothesize that patients with obstructive sleep apnea have an abno...

The Effect of Obstructive Sleep Apnea Treatment on Dizziness, Vertigo

Obstructive Sleep Apnea may cause dizziness or vertigo through hypoxia of the vestibular nuclei in the brain. Treating sleep apnea may improve dizziness or vertigo.

Effects of Positive Airway Pressure (PAP) in Children With Obstructive Sleep Apnea (OSA)

Obstructive sleep apnea is a problem for a large number of children and can result in problems with thinking patterns, behaviors and sleep if left untreated. Little is known about how posi...

REV 002 Observational Study of the ReVENT Sleep Apnea System: Minimally Invasive Treatment for Obstructive Sleep Apnea

The purpose of this post-market observational study is to assess the effectiveness and patient perception of benefit of the ReVENT Sleep Apnea System in patients diagnosed with Obstructive...

Differences between manual and automatic analysis in determining the severity of obstructive sleep apnea using home sleep apnea testing.

Home sleep apnea testing (HSAT) is a diagnostic measure for obstructive sleep apnea hypopnea syndrome (OSAHS) in moderate/high risk patients. Some HSAT companies contain automatic analysis (AA). Howev...

Cycle length identifies obstructive sleep apnea and central sleep apnea in heart failure with reduced ejection fraction.

To clarify whether unmasking of central sleep apnea during continuous positive airway pressure (CPAP) initiation can be identified from initial diagnostic polysomnography (PSG) in patients with heart ...

Can STOP-Bang and Pulse Oximetry Detect and Exclude Obstructive Sleep Apnea?

Obstructive sleep apnea (OSA) is related to postoperative complications and is a common disorder. Most patients with sleep apnea are, however, undiagnosed, and there is a need for simple screening too...

Comparisons of measures used to screen for obstructive sleep apnea in patients referred to a sleep clinic.

Obstructive Sleep Apnea (OSA) contributes to all-cause mortality. An American Academy of Sleep Medicine task force is focusing on improving detection and categorization of OSA symptoms and severity to...

Medical and Biotech [MESH] Definitions

A condition associated with multiple episodes of sleep apnea which are distinguished from obstructive sleep apnea (SLEEP APNEA, OBSTRUCTIVE) by the complete cessation of efforts to breathe. This disorder is associated with dysfunction of central nervous system centers that regulate respiration. This condition may be idiopathic (primary) or associated with lower brain stem lesions; chronic obstructive pulmonary disease (LUNG DISEASES, OBSTRUCTIVE); HEART FAILURE, CONGESTIVE; medication effect; and other conditions. Sleep maintenance is impaired, resulting in daytime hypersomnolence. Primary central sleep apnea is frequently associated with obstructive sleep apnea. When both forms are present the condition is referred to as mixed sleep apnea (see SLEEP APNEA SYNDROMES). (Adams et al., Principles of Neurology, 6th ed, p395; Neurol Clin 1996;14(3):611-28)

Disorders characterized by multiple cessations of respirations during sleep that induce partial arousals and interfere with the maintenance of sleep. Sleep apnea syndromes are divided into central (see SLEEP APNEA, CENTRAL), obstructive (see SLEEP APNEA, OBSTRUCTIVE), and mixed central-obstructive types.

Dyssomnias (i.e., insomnias or hypersomnias) associated with dysfunction of internal sleep mechanisms or secondary to a sleep-related medical disorder (e.g., sleep apnea, post-traumatic sleep disorders, etc.). (From Thorpy, Sleep Disorders Medicine, 1994, p187)

A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness. Associated conditions include OBESITY; ACROMEGALY; MYXEDEMA; micrognathia; MYOTONIC DYSTROPHY; adenotonsilar dystrophy; and NEUROMUSCULAR DISEASES. (From Adams et al., Principles of Neurology, 6th ed, p395)

HYPOVENTILATION syndrome in very obese persons with excessive ADIPOSE TISSUE around the ABDOMEN and DIAPHRAGM. It is characterized by diminished to absent ventilatory chemoresponsiveness; chronic HYPOXIA; HYPERCAPNIA; POLYCYTHEMIA; and long periods of sleep during day and night (HYPERSOMNOLENCE). It is a condition often related to OBSTRUCTIVE SLEEP APNEA but can occur separately.
