In High Frequency Jet Ventilation, increasing driving pressure has what effect on PaCO2?

Explanation:
In High Frequency Jet Ventilation, CO2 removal is driven by the amount of fresh gas delivered with each jet pulse, so driving pressure directly influences how much gas reaches the alveoli each breath. Increasing the driving pressure raises the delivered tidal volume of the jet breaths, enhancing CO2 elimination and thus lowering PaCO2. Keep in mind that too much driving pressure can raise mean airway pressure and risk lung injury or hemodynamic compromise, but the immediate effect on PaCO2 when increasing driving pressure is a decrease.
