Some symptoms of high levels of carbon dioxide in the blood are drowsiness, inability to concentrate and headache, according to About.com. In more severe cases of high carbon dioxide, also known as hypercapnia, symptoms include flushed skin, dizziness, muscle twitches, increased blood pressure and r

In the strictest sense, blood that is being carried toward the heart is venous, while blood being carried away from the heart is arterial, according to Dictionary.com. However, with the exception of the blood carried by the pulmonary arteries and veins, blood in the arteries also carries more oxygen

The partial pressure of CO2 in Earth's atmosphere is 0.3 millimeters of mercury. Partial pressures depend upon the particular mixtures of gases involved. Inside human blood vessels, the partial pressure of CO2 or carbon dioxide is much higher because the mixture of gases inside human blood is differ
