Q

How does hyperventilation treat increasing ICP?

A

Decreases PCO2=vascular constriction=decreased space taken up in cranium=decreased pressure

17
Q

How does osmotherapy with diuretics treat increasing ICP?

A

Decreases edema only in areas with intact cells and vasculature=decreased edematous pressure=decreased ICP

18
Q

When is a craniotomy performed?

A

When the brain needs room to swell
