Driving Pressure and Transpulmonary Pressure | Anesthesiology
WEBDriving pressure (ΔP) is calculated as the difference between plateau pressure (P plat) and positive end-expiratory pressure (PEEP). Driving pressure is composed of two pressures: that distributed to the lung itself, the transpulmonary pressure (ΔP L), and that applied to the chest wall (ΔP cw).

WEBAug 4, 2017 · In this Viewpoint, we review the physiological meaning of driving pressure, look at the current clinical evidence, and discuss the role of driving pressure when setting the ventilator, considering it more as a safety limit than an objective by itself.
WEBOct 3, 2016 · Driving pressure is Vt/Crs (Vt being tidal volume based on ideal body weight and Crs is the compliance of the respiratory system. In patients who are not spontaneously breathing, driving pressure could also be calculated by Plateau Pressure minus PEEP. These graphs explain how it can be both: from Brower R. from JE Kenny.

Driving Pressure for Ventilation of Patients with Acute Respiratory
WEBDriving pressure, although directly measured from the ventilator, is a function of both V T and respiratory system compliance (driving pressure = V T / respiratory system compliance). Both increases in V T and decreases in respiratory system (lung, chest wall) compliance can increase driving pressure.

The future of driving pressure: a primary goal for mechanical
WEBOct 4, 2018 · Driving pressure is the plateau airway pressure minus PEEP. It can also be expressed as the ratio of tidal volume to respiratory system compliance, indicating the decreased functional size of the lung observed in patients with ARDS (i.e., baby lung).

Driving Pressure: The Road Ahead | Respiratory Care
WEBAug 1, 2019 · Driving pressure is a strong independent predictor of mortality and may be a key mediator of current lung-protective ventilation strategies. 5,7–10 Reductions in tidal volume or increases in PEEP are only associated with improved survival if they concomitantly result in decreases in driving pressure. 5 Although there is robust …

Driving pressure: applying the concept at the bedside
WEBMay 16, 2023 · Driving pressure (Δ P) is defined as the distending pressure above the applied positive end-expiratory pressure (PEEP) required to generate tidal volume (Vt). It is generated by the elastic forces developed during tidal inflation.
