What exactly do you mean by a 02 ventilator? What exactly are you asking. If your stroke is not breathing they need to be intubated (breathing tube inserted) and placed on a ventilator. Did you mean "hyperventilation" and CVA? What do you mean by ventilator?
Too much O2 doesn't cause vasodilation, per se.... Hyperventilation is the blowing off of excess CO2 (as well as the "sometimes" administration of excess amount of O2). Initially the lowering of CO2 will help to decrease the intracranial pressure and will cause an initial decrease of intracranial pressure.....but will increase the intracranial pressure if CO2 dropped too low and for extended periods of time.
