Abstract
For VILI what matters is a tidal volume in a ventilatable lung Tidal strain ≥ 1.5 and total stress around 20 cmH2O in man are possible thresholds. The stress risers allow to reach the threshold locally and a moltiplication of pressure is nearly 2 PEEP does not produce energy load and its positive effects may be due to the decraesed tidal volume
