Oscillatory chest wall compression device with improved air pulse generator with vest characterizing

摘要

An improved method of producing high frequency chest wall oscillations (HFCWO) includes generating oscillating pneumatic pressure and applying an oscillating force to a patient's chest that corresponds to the oscillating pneumatic pressure according to a protocol. The patient selects from a plurality of modes corresponding to protocols that change the oscillation frequency over time, while maintaining the bias line pressure.
