The standard treatment for acute respiratory distress syndrome (ARDS) is supportive in the form of low tidal volume ventilation applied after significant lung injury has already developed. Nevertheless, ARDS mortality remains unacceptably high (> 40%). Indeed, once ARDS is established it becomes refractory to treatment, and therefore avoidance is key. However, preventive techniques and therapeutics to reduce the incidence of ARDS in patients at high-risk have not been validated clinically. This review discusses the current data suggesting that preemptive application of the properly adjusted mechanical breath can block progressive acute lung injury and significantly reduce the occurrence of ARDS.
Core tip: In all patients at risk of developing acute lung injury or acute respiratory distress syndrome (ARDS), protective mechanical ventilation should be applied immediately upon intubation. However, the optimally protective breath to block progressive acute lung injury is not known. Recent clinical studies have shown that preemptive low tidal volume can both reduce and increase mortality. Application of preemptive airway pressure release ventilation has shown a great deal of promise at reducing ARDS occurrence in both animal and clinical studies.
