In oscillator ventilation, amplitude adjustments primarily regulate gas delivery during which phase and gas removal during which phase?

Explanation:
The main idea is that amplitude in oscillator ventilation represents the swing in pressure from peak to trough, which sets how much gas moves in and out with each cycle. When the piston moves toward inspiration, it pushes gas into the lungs, so larger amplitude increases gas delivery during the inspiratory phase. When the piston moves toward expiration, gas is expelled from the lungs, so the same amplitude also enhances gas removal during the expiratory phase. In HFOV, mean airway pressure keeps the lungs open, frequency sets how fast the cycles occur, and amplitude adjusts tidal movement and CO2 clearance by influencing both the inspiratory delivery and expiratory removal of gas. Therefore, amplitude controls gas delivery during inspiration and gas removal during expiration.
