Ventilator-associated Lung Injury - Prevention

Prevention

Preventing alveolar overdistension – Alveolar overdistension is mitigated by using small tidal volumes, maintaining a low plateau pressure, and using pressure limited ventilation.

Preventing cyclic atelectasis – Applied positive end-expiratory pressure (PEEP) is the principal method used to keep the alveoli open and lessen cyclic atelectasis.

Open lung ventilation – Open lung ventilation is a ventilatory strategy that combines small tidal volumes (to lessen alveolar overdistension) and an applied PEEP above the low inflection point on the pressure-volume curve (to lessen cyclic atelectasis).

Non-conventional ventilation as a technique for management

High frequency ventilation is thought to reduce ventilator-associated lung injury, especially in the context of ARDS and acute lung injury.
