BACKGROUND Recent studies suggest that acute pulmonary congestion induces hyperventilation and that hyperventilation-related hypocapnia leads to ventilatory control instability and central sleep apnea. Whether chronic pulmonary congestion due to congestive heart failure (CHF) is associated with central apnea is unknown. We hypothesized that CHF patients with central apnea would have greater pul...

Jul 28, 2010. Can a cervical surgery and plates cause sleep apnea. Jan 16, 2014. Sleep apnea is common among spinal cord injury patients, a small new. Central sleep apnea, on the other hand, is rarer, and is caused by . Obstructive sleep apnea syndrome (OSAS) is a multi-factorial disease with many and hypopneas caused by repetitive collapse of the upper airway during sleep. deviations in patien...

OBJECTIVE Given that 30% to 40% of children have persistent obstructive sleep apnea (OSA) after adenotonsillectomy, we evaluated whether children with hypopnea-predominant OSA were more likely to have complete disease resolution after adenotonsillectomy than those with apnea-predominant disease. We also identified risk factors that might modify the relationship between disease resolution and po...

Sleep apnea is defined as repetitive episodes of decreased or total cessation of respiratory airflow during sleep, leading to a fall in oxygen saturation of 4% and sleep fragmentation. Sleep apnea can be central or obstructive. Central sleep apnea (CSA) is characterized by apneas secondary to diminution or cessation of thoraco-abdominal respiratory movements (due to dysfunction of central respi...

Epidemiologic studies show that sleep apnea increases risks for cardiovascular disease independently of individuals’ demographic characteristics or risk markers i.e., smoking, alcohol, obesity, diabetes, dyslipidemia, atrial fibrillation, and hypertension. Individuals with severe sleep apnea are at increased risk for pulmonary arterial hypertension. The underlying mechanisms explaining associat...

AIM To assess the relationship between severity of gastroesophageal reflux disease and apnea-hypopnea index (AHI) as an indicator of the severity of obstructive sleep apnea. METHODS Data of 57 patients with proven obstructive sleep apnea and gastroesophageal reflux disease were analyzed. Patients were divided into two groups according to severity of the sleep apnea: "mild-moderate" (A)-AHI >o...

To the Editor: The recent update of the report “Practice Guidelines for the Perioperative Management of Patients with Obstructive Sleep Apnea” by the American Society of Anesthesiologists Task Force on Perioperative Management of Patients with Obstructive Sleep Apnea did not provide any new recommendations.1 Like its predecessor, the updated version includes “table 2,” a scoring system for peri...

OBJECTIVE This study was conducted to investigate the sleep symptoms and polysomnographic patterns of obstructive sleep apnea in overweight and obese children. MATERIALS & METHODS Overweight or obese children aging 6-18 yr old referred during 2010 to Endocrinology Clinic of Ghods Hospital in Ghazvin, central Iran were enrolled in the study. Polysomnography was done for the diagnosis of obstru...

OBJECTIVE Obstructive sleep apnea syndrome is associated with cardiovascular diseases and thromboembolic events. The mean platelet volume (MPV) is a predictor of cardiovascular thromboembolic events. The aim of the present study is to investigate the association between the MPV and disease severity in patients with obstructive sleep apnea syndrome. METHODS We prospectively included 194 obstru...
