摘要
A pneumatic ventilation system delivers high amplitude, low frequency oscillatory flows while maintaining the load impedance at a specified mean pressure, thereby accurately controlling mean airway pressure, oscillation amplitude, and frequency content allowing use in applications to optimize high frequency ventilation protocols in patients. The pneumatic ventilation system includes a pneumatic pressure oscillator based on a proportional solenoid valve to provide forced oscillatory excitations to a respiratory system over a bandwidth suitable for mechanical impedance measurements and high frequency ventilation.
