as a sleep technologist, your ability to identify sleep disorders such as central sleep apnea is essential in order to enable the physician to determine a correct diagnosis and prescribe the appropriate therapy. if your patient is experiencing symptoms or signs of csa, they should contact their doctor and visit you for a sleep study. with a split-night study, you monitor your patient during the first part of their night, then initiate continuous positive airway pressure (cpap) for the rest of the night if osa is evident. it is a type of sleep apnea therapy that delivers air pressure to the patient’s airway using a nasal mask that your patient wears on their face while they sleep.
asv is a newer type of pap device that monitors your patient’s breathing issues continuously and adjusts as needed to maintain breathing. a common complaint of the cpap device is that the constant pressure is uncomfortable for them to breathe against when they exhale; which can be a challenge if they’re using cpap at higher pressures. because the device is implantable and activates automatically, it does not require wearing a mask; however, as with any implantable device procedure, there is a risk of implant site infection. for more information on central sleep apnea, and to obtain a must-read reference guide for sleep technologists who are looking to advance their knowledge, click here to download our ebook, sleep technology terms & definitions.
idiopathic or primary central sleep apnea is a rare sleep breathing disorder characterized by periodic episodes of apnea or hypopnea resulting from absent or decreased inspiratory effort due to decreased central neural input to the respiratory motor neurons. primary central sleep apnea patients usually present with complaints of witnessed apneas, restless sleep, insomnia, and/or excessive daytime sleepiness. berry rb, budhiraja r, gottlieb dj, et al. deliberations of the sleep apnea definitions task force of the american academy of sleep medicine. j clin sleep med. prevalence and characteristics of central compared to obstructive sleep apnea: analyses from the sleep heart health study cohort. sleep. badr ms, toiber f, skatrud jb, dempsey j. pharyngeal narrowing/occlusion during central sleep apnea. xie a, wong b, phillipson ea, slutsky as, bradley td. interaction of hyperventilation and arousal in the pathogenesis of idiopathic central sleep apnea. xie a, rutherford r, rankin f, wong b, bradley td.

primary central sleep apnea. this is an uncommon condition in which 5 or more central apneas, lasting 10 seconds or more, occur per hour of 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. central sleep apnoea (csa) is characterised by recurrent apnoeas during sleep with no associated respiratory effort. it, idiopathic central sleep apnea, idiopathic central sleep apnea, can central sleep apnea be cured, central sleep apnea death, central sleep apnea causes.
central sleep apnea occurs because your brain doesn’t send proper signals to the muscles that control your breathing. this condition is different from obstructive sleep apnea, in which you can’t breathe normally because of upper airway obstruction. central sleep apnea is less common than obstructive sleep apnea. central sleep apnea (csa) is a breathing disorder that causes your body to decrease or stop the effort of breathing during sleep. whereas osa is extremely common in the adult population, central sleep apnea (csa) affects less than 10% of patients referred to sleep primary central sleep apnea: the breathing pattern with primary central sleep apnea consists of the repeated absence of airflow and, central sleep apnea diagnosis criteria, supplemental oxygen for central sleep apnea.
