BACKGROUND Previous studies have documented a high prevalence of atrial fibrillation (AF) in individuals with obstructive sleep apnea (OSA). Central sleep apnea (CSA) has been associated with AF in patients with heart failure. However, data from prospective cohorts are sparse and few studies have distinguished the associations of obstructive sleep apnea from CSA with AF in population studies. ...

STUDY OBJECTIVES The objective was to investigate the prevalence of heart attack, angina pectoris, stroke, hypertension, diabetes mellitus, chronic obstructive pulmonary disease, asthma and obesity in relation to the presence and severity of obstructive sleep apnea. METHODS The sample consisted of 1887 patients, with mean age of 48.6 years (range 16-83 years), referred to a university hospita...

OBJECTIVES To describe, in infants aged 1-4 months old living at 3200 meters above sea level (MASL), oxygen saturation (SpO2), sleep apnea indices, and periodic breathing (PB) during sleep. Polysomnographies were done in 18 healthy infants. RESULTS The median SpO2 was 87%, and the median PB was 7.2% for the total sleep time. The median central sleep apnea index was 30.5/hour, which decreased ...

background and objective: failure in diagnosis and treatment of sleep apnea in children lead to physical and mental growth retardation, cardiopulmonary, and/or behavioral disorders. this study was aimed to evaluate polysomnographic (psg) and clinical findings of sleep apnea in children referred to a sleep clinic in qazvin, iran. materials and methods: this cross-sectional study was conducted am...

We describe the case of a 12-year-old boy who developed temporal lobe epilepsy (TLE) with daily complex partial seizures (CPS) and monthly generalized seizures. Moreover, he frequently snored while asleep since early childhood. Polysomnography (PSG) revealed severe obstructive sleep apnea with apnea–hypopnea index (AHI) of 37.8/h. Video-PSG with simultaneous electroencephalography (EEG) recordi...

Two cases of polygraphically defined central sleep apnea were successfully treated with the tongue retaining device, an oral prosthesis designed to reduce hypopharyngeal obstruction. The tongue retaining device may be an alternative to CPAP in the treatment of some cases of central sleep apnea.

In this paper Self-Advising SVM, a new proposed version of SVM, is investigated for sleep apnea classification. Self-Advising SVM tries to transfer more information from training phase to the test phase in compare to the traditional SVM. In this paper Sleep apnea events are classified to central, obstructive or mixed, by using just three signals, airflow, abdominal and thoracic movement, as inp...

The sleep-related breathing disorders have been categorized in various ways. The most basic schema divides them into obstructive or central apneic events. An American Academy of Sleep Medicine (AASM) Task Force Report published in 1999 defined four separate syndromes associated with abnormal respiratory events during sleep among adults, namely, obstructive sleep apnea-hypopnea syndrome (OSAHS),...

Patients with Down syndrome (DS) are at risk for both obstructive sleep apnea (OSA) and central sleep apnea (CSA); however, it is unclear how these components evolve as patients age and whether patients are also at risk for hypoventilation. A retrospective review of 144 diagnostic polysomnograms (PSG) in a tertiary care facility over 10 years was conducted. Descriptive data and exploratory corr...

Obstructive sleep apnea is common in patients with heart failure. This case illustrates that treatment with PAP therapy can improve cardiac function in patients with both conditions. CPAP-emergent central apnea, as seen in this patient, has multiple etiologies. It is commonly seen in patients with severe sleep apnea, usually resolves over time, and does not need treatment with adaptive servoven...
