“…Conversely, in a multicenter prospective study conducted by 15 Spanish PICUs, the pediatric definition of VAE based on slighter PEEP increases (PEEP-PedVAE) was the least restrictive, and it was the only VAE definition that was independently associated with increased MV and length of ICU stay in children.

[ 46 ] Thus, a unified PedVAE definition is needed.…”
