Driving pressure: pearls & pitfalls

An important parameter to guide safe mechanical ventilation is driving pressure. In this article, we learn how to calculate driving pressure, its origin, and most importantly, how to use it in clinical practice.

Driving pressure (DP or ΔP) is calculated by taking the difference between the pressure at end inspiration (when flow is 0) and the pressure at end expiration (when flow is 0). This means that…
