DEVICE AND METHOD OF REDUCING BIAS FLOW IN OSCILLATORY VENTILATORS

摘要

A device and method of ventilating a patient reduces the bias flow relative to existing oscillatory ventilators. The device has an oscillator (11), and an oscillating line (14) having a first end in sealing relationship with the oscillator. A gas supply line (8) is connected to the oscillating line, and a patient line (25) is connected to a second end of the oscillating line. An outlet valve (52) is in pneumatic communication with the patient line.
