Nursing care facility Treatment Does the brain swell?? The more damage the brain receives,
the more it swells. This is caused by leakage
from blood vessels.
When the brain swells it leads to a rise in pressure
within the brain Intracranial pressure (ICP)
Brain swelling occurs when there
is an increase in the amount of blood
to the brain.
Brain edema is when water may collect
in the brain.
Both brain swelling and brain edema result
in excessive pressure to the brain called intracranial
pressure. Prognosis??? Unknown ... Preguntas?? Loss of consciousness, not
longer than 30 minutes
