Central Sleep Apnea

Central sleep apnea and hypoventilation syndromes are increasingly important clinical entities, in part because of their associations with pervasive conditions such as heart failure and obesity. While disruption of ventilatory control appears to contribute to these disorders, much remains unknown about pathophysiologic mechanisms and optimal treatment methods. Central sleep apnea during sleep-wake transition: Up to 40% of healthy individuals may exhibit central apneas during sleep-wake transition. The central apneas occur during the period that chemoreceptors are resetting and an instability of ventilation control occurs. Central sleep apnea is less easily treated, as it is a failure of the central nervous system to continue the breathing process during some point or points in the sleep cycle. This means that there is no physical blockage, but rather that the brain essentially "forgets" to breathe.

Central sleep apnea (CSA) is caused by irregularities in the brain’s normal signals to breathe. Most people with sleep apnea will have a combination of both types. Central sleep apnea is rare. This type is called central apnea because it is related to the function of the central nervous system. Central sleep apnea is more rare sleep disorder and occurs when the brain does not tell the body to breathe during sleep.

Central sleep apnea and central hypopnea are due to inadequate signals coming from the brain telling the chest and lungs to expand. Central sleep apnea (CSA) is caused by irregularities in the brain's normal signals to breathe. Most people with sleep apnea will have a combination of both types. Central sleep apnea (CSA) is characterized by the periodic occurrence of apnea caused by loss of ventilatory motor output. CSA is often discussed as a minor variant of obstructive sleep apnea.However, this view obscures the critical contribution of CSA as an important manifestation of breathing instability in a variety of conditions with diverse causes.

Central sleep apnea (CSA) occurs when the brain does not send the signal to the muscles to take a breath, and there is no muscular effort to take a breath. Obstructive sleep apnea (OSA) occurs when the brain sends the signal to the muscles and the muscles make an effort to take a breath, but they are unsuccessful because the airway becomes obstructed and prevents the flow of air. Central sleep apnea is uncommon, and when present, is often associated with severe heart failure or the result of a stroke. Central sleep apnea is caused by problems in the central nervous system, which includes the brain and spinal cord. In some cases, the brain may not send the message to the muscles involved in breathing.

Central sleep apnea is more common at high elevations. Central sleep apnea is much less common than obstructive sleep apnea. This condition occurs when the brain fails to send the proper signals to the muscles that control breathing. Central sleep apnea is estimated at 5% in people older than 65 years and from 1.5% to 5% in men less than 65 years old.

Central sleep apnea is when the brain doesn't send the proper signals to the muscles that control breathing. Mixed sleep apnea is a combination of the two. Central sleep apnea is diagnosed by MRI and night-long polygraphic sleep monitoring. Central sleep apnea syndrome is typically characterized by a slowing down or stopping of breathing while asleep, caused by oxygen desaturation. Patients will complain of insomnia though excessive sleepiness can also occur.
