Respiratory and other symptoms of hypocarbia. Since hypocapnia is based on chronic hyperventilation, its symptoms are the same as the symptoms of hyperventilation. They are very wide and range from chronic coughing and nasal congestion, to constipation, coughing and muscle cramps.
The reduction in cerebral blood flow is marked. Cerebral blood flow (CBF) decreases quite markedly with hypocapnia: a decrease of 4% per mmHg reduction in pCO2. For example, an acute drop in pCO2 from 40 down to 25mmHg will decrease CBF by about 60%. In awake subjects this can cause light-headedness and even confusion.
