Carbon dioxide is a common gas in the air which has been widely used in medical treatment. A carbon dioxide molecule consists of two oxygen atoms and one carbon atom through a covalent bond. In the body, carbon dioxide reacts with water to produce
carbonic acid
. In healthy people, carbon dioxide is maintained within a narrow range (35-45 mmHg) by physiological mechanisms. The role of
hypocapnia
(partial pressure of carbon dioxide < 35 mmHg) and hypercapnia (partial pressure of carbon dioxide > 45 mmHg) in the nervous system is intricate. Past researches mainly focus on the effect of
hypocapnia
to nerve protection. Nevertheless, Hypercapnia seems to play an important role in neuroprotection. The mechanisms of
hypocapnia
and hypercapnia in the nervous system deserve our attention. The purpose of this review is to summarize the effect of
hypocapnia
and hypercapnia in stroke and traumatic brain injury.
