Hi:
Can anyone help me with this contradiction I have encountered, in what happens with ICP pts?
I have learnt that ICP patients hyperventilate (central neurogenic hyperventilation) and this expels CO2, and thus constrict the vessels to make more room for the cranial pressure. And then, I read that the body also responds the opposite - poor CPP will cause increased bp and dilate the vessels. So what really happens? dilation or constriction?
Thanks for any help.
