Q

Why do we want to maintain a high BP of someone with a hemorrhagic stroke?

A

Their body is used to that high pressure. And if we were to drop it too low, we would cause vasospam tightening that makes it worse.

Q

Why is it that a hemorrhage patient could end up with the intra-ventricular hemorrhage on top of their already existing hemorrhage (in the ventricles)?
Why is this important to avoid?

A

Rupture of the lateral ventricle can occur and cause more pressure on the ventricles and then the bleed is even bigger.
If it gets to this point, they will be losing a lot of blood and its very fatal.
