  https://www.mayoclinic.org/diseases-conditions/central-sleep-apnea/symptoms-causes/syc-20352109

  Central sleep apnea occurs because the brain doesn’t send proper signals to the muscles that control breathing. […] Consult a medical professional if you have or if your partner notices any symptoms of central sleep apnea, particularly: Shortness of breath that awakens you from sleep. […] Central sleep apnea occurs when your brain doesn’t transmit signals to your breathing muscles. […] The brainstem links the brain to the spinal cord. It controls many functions, including heart rate and breathing. Central sleep apnea can be caused by a number of conditions that affect the ability of the brainstem to control breathing. […] Some people with obstructive sleep apnea develop central sleep apnea while using continuous positive airway pressure (CPAP) for treatment. This condition is known as treatment-emergent central sleep apnea. […] Excessive daytime drowsiness can be due to other disorders, so it’s important to get an accurate diagnosis.

• #3 Central Sleep Apnea in Adults: An Interdisciplinary Approach to Diagnosis and Management—A Narrative Review

  https://www.mdpi.com/2077-0383/14/7/2369

  Central sleep apnea (CSA) is a heterogeneous group of sleep-related breathing disorders characterized by intermittent absence of respiratory effort during sleep. […] This review outlines the pathophysiology of CSA, emphasizing ventilatory instability and brainstem dysfunction as key mechanisms. […] Diagnostic approaches encompass polygraphy, polysomnography, and various laboratory tests to evaluate comorbidities. […] The mechanism of CSA production, unlike OSA (which presents respiratory effort), consists in the lack of transmission of nervous impulses from the respiratory centers to the respiratory muscles to trigger periodic breathing. […] CSA is found in approximately 5% of all cases of sleep apnea. […] The International Classification of Sleep Disorders, Third Edition (ICSD-3rd) describes five different CSA entities that affect adults with different clinical and polysomnographic (PSG) features.

• #7 Central Sleep Apnea in Adults: Diagnosis and Treatment

  https://pmc.ncbi.nlm.nih.gov/articles/PMC10204934/

  The hallmark of CSA is transient cessation of airflow during sleep due to a lack of respiratory effort triggered by the brain. This is in contrast to OSA, in which there is absence of airflow despite continued ventilatory effort due to physical airflow obstruction. The gold standard for the diagnosis and optimal treatment assessment of CSA is in-laboratory polysomnography (PSG) with esophageal manometry, but in practice, respiratory effort is generally estimated through oronasal flow and respiratory inductance plethysmography bands placed on the chest and abdomen during PSG. […] A systematic clinical approach should be used to identify and treat CSA. […] Primary CSA has been defined in the International Classification of Sleep Disorders 3rd edition (ICSD-3) with the following criteria: (1) diagnostic PSG with 5 events per hour of CSAs and/or central hypopneas per hour of sleep; the number of CSAs and/or central hypopneas is 50% of the total number of apneas and hypopneas; and there is no evidence of Cheyne-Stokes breathing (CSB); (2) the patient reports sleepiness, awakening with shortness of breath, snoring, witnessed apneas, or insomnia; (3) there is no evidence of nocturnal hypoventilation; and (4) the disorder is not better explained by another medical use, substance use disorder (SUD), or other current sleep, medical, or neurologic disorder.

  https://www.mountsinai.org/care/ent/services/sleep-surgery/diagnosis-testing

  An evaluation of the head and neck through an office visit with an otolaryngologist can be a great start for determining if you or a loved one has obstructive sleep apnea. A standard visit with a full medical and sleep history, as well as an in-depth physical examination of the airway will determine any signs of nasal or throat/tongue obstruction and narrowing. If a concern arises, our Sleep Surgery team will request and assist with facilitating a sleep study at the Center for Sleep Medicine at Mount Sinai. […] The primary definitive method of diagnosing whether you have sleep apnea is through an overnight sleep study or polysomnography (PSG). This exam can be done in a sleep lab where you arrive at night (weeknights and weekends are usually available) and you sleep in a room similar to a hotel room with monitors. These monitors measure muscle movements, sleep stages, snoring, sleep apnea, and oxygen levels. An overnight PSG is considered the gold standard for diagnosing sleep apnea.

  If you have symptoms of sleep apnea, your doctor may ask you to have a sleep apnea test, called a polysomnogram (PSG). This may be done in a sleep disorder center or even at home. […] A polysomnogram — or sleep study — is a multiple-component test that electronically sends and records specific physical activities while you sleep. The recordings are analyzed by a qualified sleep specialist to find out if you have sleep apnea or another type of sleep disorder. […] If the test shows sleep apnea, you may need more sleep testing to figure out the best treatment option. […] It takes the sleep specialist some time to go over the hundreds of pages of data from the study. Theyll send the results to your doctor.

  In addition to risk factors, numerous signs and symptoms can suggest OSA, but polysomnography is the diagnostic standard. […] Predictive clinical features of OSA include observed gasping during sleep, morning headache, excessive daytime sleepiness, loud snoring, and neck circumference of greater than 16 inches (40.6 cm). […] There are several screening questionnaires for OSA, although the accuracy of many of them is limited. […] The STOP-Bang questionnaire is a validated screening tool, particularly in obese and surgical patients. […] Sleep studies performed in a sleep laboratory or in the home can quantify the apnea-hypopnea index, which is required to diagnose OSA.

  The diagnostic evaluation of CSA consists of evaluating the patient’s signs and symptoms in concert with diagnostic testing. These factors are imperative in deciding on treatment options. Signs and Symptoms: A number of signs and symptoms of CSA are identical to those in OSA, and distinguishing the two can be challenging. […] Importantly, patients with CSA and heart failure may well have fewer symptoms of sleepiness than what might be expected for their degree of physiological derangement, and sleepiness may be a poor predictor of CSA. […] Objective Testing: Since diagnosing CSA may be challenging, full-night polysomnogram (sleep study) is recommended to determine the frequency and pattern of central apnea. […] Home sleep studies (often referred to as „portable monitoring”) in the diagnosis of CSA have not been broadly accepted as of yet, and overnight oximetry alone does not provide sufficient physiological detail to discriminate CSA from OSA.

  A sleep-related disorder in which blood oxygen is reduced due to the interruption of the normal breathing cycle during sleep, central sleep apnea can be divided into three main subtypes, detailed by the DSM-5. […] Two main criteria are employed in the diagnosis of central sleep apnea (American Psychiatric Association, 2013). Firstly, the patient must have more than four central sleep apneas for every hour of sleep. This can be determined through polysomnographs, which are used to detect and diagnose a variety of sleep-related disorders. The second criterion is that the apneas are not caused by some other sleep disorder. […] Several techniques that test for the existence of central sleep apnea have been developed. Magnetic imaging resonance (MRI), for example, can be used to detect morphological features of the brain stem that correspond with central sleep apnea (Duning et al., 2013). […] Their new system is based on wireless signaling among a monitoring unit, a receiver, and a transmitter. In this way, vital signs associated with sleep apneas can be analyzed and a diagnosis of central sleep apnea can be made.

  An AHI of greater than 5 in the absence of periodic breathing and an AHI of greater than 10 in the presence of periodic breathing is required to make a diagnosis of central sleep apnea due to drugs or substance abuse. […] Esophageal pressure monitoring with a balloon catheter is helpful in distinguishing central from obstructive events by revealing the substantial reduction in intrapleural pressure that occurs with the obstructive events. […] No studies have evaluated the accuracy of portable monitoring devices for the detection of central apneas, but CSA can be suspected from review of tracings on many portable monitoring platforms.

These conditions are characterized by a history of a preexisting disorder of hypoventilation, elevated resting PaCO2, and severe oxygen desaturation during sleep, which is more prominent during REM sleep in contrast to primary central sleep apnea and Cheyne-Stokes breathing-central sleep apnea (CSB-CSA), which are mostly observed during NREM sleep.

• #47 Central sleep apnea – Wikipedia

  https://en.wikipedia.org/wiki/Central_sleep_apnea

  Central sleep apnea (CSA) or central sleep apnea syndrome (CSAS) is a sleep-related disorder in which the effort to breathe is diminished or absent, typically for 10 to 30 seconds either intermittently or in cycles, and is usually associated with a reduction in blood oxygen saturation. […] A diagnosis of sleep apnea requires determination by a physician. The examination may require a study of an individual in a sleep lab, although the AAST has said a two belt IHT (In Home Test) will replace a PSG for diagnosing obstructive apnea. […] During a PSG (polysomnography) (a sleep study), a person with sleep apnea shows breathing interruptions followed by drops/reductions in blood oxygen and increases in blood carbon dioxide level. […] As noted above, in central sleep apnea, the cessation of airflow is associated with the absence of physical attempts to breathe; specifically, polysomnograms reveal correlation between absence of rib cage and abdominal movements and cessation of airflow at the nose and lips.
