title: A case of dirhythmic breathing.
abstract: We describe a case of dirhythmic breathing in a 60-year-old man after neurosurgery. A large hemangioblastoma was removed from the cerebellum at the level of the fourth ventricle. The spirometric tracings showed two types of respiratory cycles: the rhythm. A was stable with a short inspiratory time; sometimes a second type of respiratory cycle, B, was present or erratically coupled with the A rhythm. It had very small tidal volume and mean inspiratory flow with phasic variations similar to those observed in Cheyne-Stokes breathing pattern.
