background info Carbon dioxide is perhaps the most potent available modulator of cerebrovascular tone and thus cerebral blood flow (CBF) http://www.liebertonline.com/doi/abs/10.1089/089771501750055776?journal Code=neu
Hypercarbia and hypoxia are both potent cerebral vasodilators that result in increased cerebral blood flow and volume and, potentially, increased ICP; thus, they must be avoided. Orotracheal intubation allows for airway protection in patients who are severely obtunded and allows for better control of oxygenation and ventilation. http://emedicine.medscape.com/article/909105-overview
