What is Cheyne-Stokes breathing? When seen? 



A type of breathing characterized by rhythmic variations in 

 intensity, occurring in cycles. Each cycle consists of a gradual 

 decrease in the intensity of the respiratory movements, followed by 

 total cessation for a space of from five to forty seconds; this in 

 turn is followed by a gradual increase of the respiratory movements 

 until they reached a maximum and become dyspnoeie in character. 

 This type of breathing is seen in severe cerebral diseases such as 

 uraemic coma and cerebrospinal meningitis.
