however, the poor initial experience of compsas patients with cpap may not be avoided, and nonadherence with continued therapy may often result. so the definition of compsas may be broadened to include diagnosis of compsas in non-cpap-treated patients who are managed with, for example, a dental appliance or a surgical procedure. the ventilatory output to a given change in pao2 or paco2 can vary greatly among individuals and with disease status. the prevalence of 18% observed in this study accompanied by an additional 19% of patients presenting with a csa of over five per hour during cpap introduction suggests that compsas is considerably more common in those with chf, and that with increased numbers of patients with chf being screened and treated for osa, it will be an increasing clinical problem associated with compsas. in a retrospective study among japanese patients, the prevalence of compsas among males and females with osa was 5.3% and 1.1%, respectively.33 morgenthaler et al4 found that 81% of patients with compsas were men.
in all these studies, compsas patients had a higher cai and showed that the majority of central apneas occurred during nrem sleep in psg. dernaika et al,30 in their prospective case-control study, documented the disappearance of central apnea activity with cpap in 12 (86%) of 14 patients with compsas over 2–3 months. other research included 39 patients with compsas and found that there was no difference in any of the polysomnographic indices on cpap and bi-level pap.49 however, morgenthaler et al7 reported that bi-level pap was effective in normalizing breathing and sleep parameters. the benefit of asv has been shown in patients with heart failure and csa in both short and long-term studies, and many researchers suggest a future for this technology.51–56 asv devices have been shown to be effective in controlling compsas activity. the results of the study indicate that two servo-ventilation devices are a comparable means of controlling compsas and that compliance with them is high. a positive response to the adjunctive use of acetazolamide in this case suggests that acetazolamide may have utility in the broader management of compsas related to chronic opioid therapy.
central sleep apnea occurs because your brain doesn’t send proper signals to the muscles that control your breathing. central sleep apnea is less common than obstructive sleep apnea. treatments for central sleep apnea might involve treating existing conditions, using a device to assist breathing or using supplemental oxygen. however, snoring may not be as prominent with central sleep apnea as it is with obstructive sleep apnea. consult a medical professional if you have — or if your partner notices — any signs or symptoms of central sleep apnea, particularly the following: ask your doctor about any sleep problem that leaves you chronically fatigued, sleepy and irritable. central sleep apnea can be caused by a number of conditions that affect the ability of your brainstem — which links your brain to your spinal cord and controls many functions such as heart rate and breathing — to control your breathing. this type of central sleep apnea is most commonly associated with congestive heart failure or stroke.
during the weakest breathing effort, a total lack of airflow (central sleep apnea) can occur. some people with obstructive sleep apnea develop central sleep apnea while using continuous positive airway pressure (cpap). it is a combination of obstructive and central sleep apneas. other people may be treated with a different kind of positive airway pressure therapy. people with central sleep apnea often have severe fatigue, daytime drowsiness and irritability. you might have difficulty concentrating and find yourself falling asleep at work, while watching television or even while driving. sudden drops in blood oxygen levels that occur during central sleep apnea can adversely affect heart health. a single copy of these materials may be reprinted for noncommercial personal use only.
complex sleep apnea syndrome (compsas) is a distinct form of sleep-disordered breathing characterized as central sleep apnea (csa), central sleep apnea is a disorder in which your breathing repeatedly stops and starts during sleep. central sleep apnea occurs because your complex sleep apnea (compsa) is a form of central apnea specifically identified by the persistence or emergence of central apneas or hypopneas upon exposure to, .
complex sleep apnea is the term used to describe a form of sleep disordered breathing in which repeated central apneas (>5/hour) persist or emerge when obstructive events are extinguished with positive airway pressure (pap) and for which there is not a clear cause for the central apneas such as narcotics or systolic summary complex sleep apnoea syndrome (compsas) is a type of central apnoea characterised by the development or persistence of central apnoeas or hypopnoeas central sleep apnea (csa) is when you regularly stop breathing while you sleep because your brain doesn’t tell your muscles to take in air. complex sleep apnea is also referred to as treatment-emergent central sleep apnea. complex sleep apnea occurs when someone who previously had, .
