Review of this Chart:

On Gas Anesthesia, The Cerebral Blood Flow increases even Higher in Response to Increased PaCO2. You’re not going to need as High of Levels of PaCO2 to Increase Cerebral Bloow Flow

Even with Normal Ventilation PaCO2 (40mmHg), Cerebral Blood Flow is going to Increase Significantly under Inhalant

We are going to Midly Hyperventilate patients with CNS Disease under Inhalant Anesthesia, because with Inhalants normal Levels of CO2 will still Increase Intracranial Pressure

Review of this Chart:

In a normal animal, Cerebral Blood Flow will be normal between 60-140 MAP. If the MAP is above or below that Interval there will not be Normal Cerebral Blood Flow

The Cerebral Blood Flow begins to Increase when the PaO2 Drops below 50- Flow will Increase to try to get more Oxygenation to Tissues

PaCO2 has a Linear Relationship with Cerebral Blood Flow (CBF). As PaCO2 Increases, so does Cerebral Blood Flow

*The More CO2, the more Cerebral Blood Flow, The More Intracranial Pressure- BAD. We want to keep the CO2 LOW
