WebOct 14, 2024 · Airway Pressure = Flow * Resistance + Plateau Pressure = V’ * R + V/C + PEEP When there is a decrease in compliance the plateau pressure increases. This causes a rise in PIP pressure. Thus the overall airway pressure also increases. Equivalent Circuit Model for Peak and Plateau Pressure WebProximal airway pressure, not alveolar pressure, is monitored by the ventilator. Types of Oscillators At PCH/KEMH there are three types of ventilators that can provide HFOV. Two hybrid ventilators that provide both HFOV and conventional ventilator modalities (Fabian and VN500) and the Sensormedics 3100A(SM), which is a stand-alone HFO ventilator.
