ICD-11 7A40.0 — Primary central sleep apnoea

Primary central sleep apnoea is of unknown etiology (idiopathic) and is characterised by recurrent, predominantly central apnoeas. Airflow and respiratory effort cease simultaneously in a repetitive fashion over the course of the night. The recurrent episodes of apnoea (more than five per hour) and associated arousals are sufficiently severe to cause symptoms such as daytime sleepiness, disturbed sleep, awakening with dyspnoea, or snoring.Note: A definitive diagnosis requires objective evidence based on polysomnography.

The diagnosis includes nothing.

It has no clarifying diagnoses.
