The High-Frequency Oscillatory Ventilator

Learn about strategies to use when conventional ventilation is failing, including prone positioning, HFOV, and surfactant.

Released:

September 1, 2012

Audience:

Physicians, Respiratory Therapists, Paramedics

Learning Objectives

  • Identify the two primary control variables on the high‑frequency oscillatory ventilator that govern oxygenation and ventilation

  • Explain how mean airway pressure (MAP) is generated and adjusted on the Sensormedics 3100A

  • Describe how delta pressure (ΔP, amplitude) is generated and adjusted

  • Apply standard initial HFOV setup principles when transitioning from conventional ventilation

  • Analyze how HFOV simplifies decision‑making compared with conventional ventilation
