PEEP Titration in ARDS

Quick fact

No single PEEP level works for all ARDS patients—the optimal level can vary from 5 to 20 cm H₂O, and finding it often requires balancing oxygenation against the risk of overstretching healthy lung tissue.

Why this is interesting

Imagine inflating a deflated balloon inside a rigid box—how much air should you leave in it at the end of each breath? In ARDS, doctors face a similar puzzle: setting the ventilator's baseline pressure too low lets fragile air sacs collapse, too high can damage them.
