Hypercapnia and Hypotension

[tchristifulli]

So I was reading how C02 can play a part in vasoconstriction and dilation. When you breath off too much C02 your smaller vessels constrict. My question is the harmful effects of hypercapnia and can it cause vasodilation? And why does it cause reduced hepatic function.

CO2 is a vasodilator.

Vasoconstriction is a result of sympathetic nervous system stimulation.

As far as hepatic function one factor is an increased portal vein flow and decreased hepatic artery flow.
