Complex sleep apnea occuring after intracerebral haemorrhage with treatment by adaptive servoventilation in two patients: a case report

Complex sleep apnea syndrome is not well characterized. It is supposed that complex sleep apnea syndrome is more similar to central sleep apnea syndrome than to obstructive sleep apnea. CPAP can eliminate obstructive events in obstructive sleep apnea, but often leads to accumulation of problematic central apneas instead. Central sleep apnea is referred to as instability of the breathing control system. Alveolar hypoventilation disorders, heart failure, neurological disorders and idiopathic forms of CSA are suggested as reasons. No literature seems to exist concerning new-onset of complex sleep apnea after cerebr…
