Oscillatory ventilationとは

WebApr 22, 2024 · As shown in Figure 2, the oscillator is essentially a piston in a cylinder. Air flow, called “bias flow,” passes between the cylinder and the patient, at a controlled rate (typically 20-60 LPM) and oxygen concentration (FiO2). This flow results in a mean airway pressure (mPaw). The oscillations stir the air in the patient’s lungs around the mPaw.
