  1. Hyper Mass, fraction of non-air content in the hyperinflated compartment related to the total lung mass; Norm Mass, fraction of non-air content in the normally aerated compartment related to the total lung mass
  2. Poorly-aerated Mass fraction of non-air content in the poorly aerated compartment related to the total lung mass, Non-aerated Mass fraction of non-air content in the non aerated compartment related to the total lung mass. Data is presented as median, first and third quartiles
  3. aSignificant differences compared to ARDSnet-24h
