Decreasing respiratory rate
But, the Q-stem states the anesthesiologist is HYPOventilating the patient.
decreasing respiratory rate = retention of CO2 = vasodilation of brain arteries = more filling of tubes = greater intra-cranial pressure
@hello shoot, you're right! i ended my explanation with the example of HYPERventilation when i should have done the opposite! (sorry!) ... edit: "By HYPOventilating (retaining CO2), the brain vasculature senses a high CO2 environment and vasodilates = increases intra-cranial filling and pressure!"
