Central neurogenic hyperventilation (CNH) is an abnormal pattern of breathing characterized by deep and rapid breaths at a rate of at least 25 breaths per minute. Increasing irregularity of this respiratory rate generally is a sign that the patient will enter into coma .
Activity from respiratory brain stem structures then modulates nervous activity to control lung contraction.

It is through this simple pathway that the decision to inhale or sniff may occur.
