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),...
STUDY OBJECTIVES Identify polysomnographic and demographic factors associated with elevation of nocturnal end-tidal CO2 in patients with obstructive sleep apnea. METHODS Forty-four adult patients with obstructive sleep apnea were selected such that the maximal nocturnal end-tidal CO2 was below 45 mm Hg in 15 studies, between 45 and 50 mm Hg in 14, and above 50 mm Hg in 15. Measurements includ...
Background and Objectives: Sleep apnea involves repetitive cycles of obstructive sleep that disrupt sleep. This complication is the most important modifiable risk factors for stroke. The aim of this study was to assess sleep apnea in patients with stroke. Material and Methods: In this cross-sectional study, 132 patients with stroke were recruited using convenience samplin...
There is a close relationship among the types of sleep apnea (central, obstructive, and mixed) in regard to both the pathogenesis and in the clinical management of sleep apnea syndromes. This review will recount the rationale for the use of animal models in understanding intermediate traits, such as the ventilatory responses to hypoxia and reoxygenation, seen with human sleep apnea. One feature...
These practice parameters are an update of the previously published recommendations regarding the use of autotitrating positive airway pressure (APAP) devices for titrating pressures and treating adult patients with obstructive sleep apnea syndrome. Continuous positive airway pressure (CPAP) at an effective setting verified by attended polysomnography is a standard treatment for obstructive sle...
background and objective: sleep-disordered breathing (sdb) is associated with increased morbidity and mortality in patients with heart failure (hf). we assessed the prevalence and the pattern of sdb in hf patients who were candidates for heart transplantation. materials and methods: twenty heart transplantation patients with ventricular ejection-fraction < 25% were recruited consecutively in a ...
Obstructive sleep apnea (OSA) has been the engine that has driven the remarkable growth of the sleep field over the last 25 years. Although the medical community and the general public have been interested in the performance and quality-of-life problems that result from sleep apnea, the real concern has been the potential relationship between OSA and the cardiovascular system. This goes back as...
