What is the Origin of Central Sleep Apnea?

The term is derived from "central," indicating an origin in the central nervous system, and "sleep apnea," which combines the Greek words for "without" (a-) and "breathing" (pneo), meaning a lack of breath during sleep. The clinical distinction between central and obstructive forms of apnea was established through polysomnography, allowing clinicians to differentiate the underlying pathophysiology.

What is the Mechanism of Central Sleep Apnea?

The underlying mechanism involves instability in the respiratory drive, often linked to fluctuations in carbon dioxide levels that the brainstem fails to appropriately regulate. In many cases, CSA is associated with underlying medical conditions, such as heart failure or neurological disorders, which affect the brain's chemosensors and respiratory pattern generators. This instability causes a cyclical pattern of hyperventilation followed by hypoventilation or apnea, which disrupts the normal sleep architecture.

Central Sleep Apnea

Meaning

Central Sleep Apnea (CSA) is a clinical disorder characterized by recurrent cessations or significant reductions in breathing effort during sleep due to a temporary failure of the brain’s respiratory control centers. Unlike the more common obstructive sleep apnea, the airway remains open; the problem lies in the central nervous system’s inability to send the proper signal to the muscles of respiration. This condition leads to intermittent drops in blood oxygen saturation and fragmented sleep, impacting overall health and hormonal regulation.
