The symptoms associated with high blood carbon dioxide levels include increased blood pressure, rapid pulse, rubor (redness), muscle twitches, headache, chest-pain, confusion, and fatigue. All of these symptoms depend on the severity of case.

The carbon dioxide levels are also essential in maintaining the proper pH of the blood.
