Driving Pressure, PEEP, and the ICEBERG Study

This episode breaks down the ICEBERG Study and why driving pressure may provide a clearer measure of ventilator stress and patient outcomes than plateau pressure alone. We define driving pressure, explain how it is calculated, and review evidence showing that higher driving pressures are associated with worse outcomes in mechanically ventilated patients. The discussion explores why plateau pressure can be a useful trend but may not fully reflect lung stress, how changes in PEEP can affect driving pressure and lung recruitment, and why monitoring compliance, SpO₂, and end-tidal CO₂ is essential when assessing response to ventilator adjustments. We also examine the rapid changes in lung mechanics that can occur after cardiac arrest or repeated intubations and discuss how driving pressure and compliance data, when available on transport ventilators, can help guide safe ventilator management during transport.
