  1. The arrows indicate the direction of change of each variable relative to respective NS. ↑: increase in relation to NS; ↓: decrease in relation to NS; →: no changes. ALIp, pulmonary acute lung injury; ALIexp, extrapulmonary acute lung injury; PCV, pressure-controlled ventilation; PSV, pressure support ventilation; NS, non-sigh; Ppeak,L, transpulmonary peak pressure; Pmean,L, transpulmonary mean pressure; P0.1, driving pressure; PaO2, mmHg, arterial oxygen partial pressure; mRNA IL-1β, mRNA interleukin (IL)-1 β, mRNA IL-6, mRNA interleukin (IL)-6, mRNA PCIII, mRNA type III procollagen.
