Central neurogenic hyperventilation

Central neurogenic hyperventilation is an abnormal pattern of breathing characterized by deep and rapid breaths. It is unrelated to other forms of hyperventilation like Kussmaul’s respirations.

It is caused by the body’s attempt to reduce intracranial pressure by reducing the carbon dioxide levels in the blood, causing contraction of cranial arteries; or direct damage to certain areas of the brain stem.

This abnormal breathing pattern is seen in patients with severe head injuries and with strokes involving the midbrain.
