Sleep apnea and heart failure: Part II: central sleep apnea.
In the first part of this 2-part review, we provided a synopsis of the cardiovascular effects of normal sleep and an overview of the diagnostic, pathophysiological, and therapeutic implications of obstructive sleep apnea (OSA) in the setting of heart failure (HF). In this second part, we turn our attention to central sleep apnea (CSA), commonly referred to as Cheyne-Stokes respiration. This bre...
متن کاملWhat is central sleep apnea?
Central sleep apnea (CSA) describes a group of conditions in which cessations in air flow occur without respiratory effort. In contrast, obstructive sleep apnea patients have ongoing respiratory effort during respiratory events. However, considerable overlap exists in the pathogenesis and clinical presentation of obstructive sleep apnea and CSA. A good working knowledge of the mechanisms underl...
متن کاملCentral apnea during stage 3,4 sleep.
A 45-year-old female who complained of frequent awakenings and excessive daytime sleepiness (Epworth Sleepiness Scale 16/24) was referred for a sleep study. Her husband reported that she had frequent pauses in her breathing during sleep with intermittent snoring and gasping. The patient began having sleep problems about 2 years before the sleep study. At that time she also developed severe pain...
متن کاملPathogenesis of obstructive and central sleep apnea.
Considerable progress has been made over the last several decades in our understanding of the pathophysiology of both central and obstructive sleep apnea. Central sleep apnea, in its various forms, is generally the product of an unstable ventilatory control system (high loop gain) with increased controller gain (high hypercapnic responsiveness) generally being the cause. High plant gain can con...
متن کاملReversal of central sleep apnea with oxygen.
OBJECTIVE To examine the effect of oxygen on apneas and sleep quality in patients with frequent central apneas during sleep. DESIGN/SUBJECTS Prospective intervention study of 20 consecutive patients with predominant central apnea identified from 570 patients referred for suspected sleep apnea syndrome. Sixteen patients had congestive heart failure and seven of them had a previous stroke. Thre...
