PEEP= Positive End-Expiratory Pressure; ICU= Intensive care Unit; PLE= Expiratory Transpulmonary Pressure; ElastanceL= Elastance of the Lung; ElastanceCW= Elastance of the Chest Wall; EELV= End-Expiratory Lung Volume; PaO2/FiO2= arterial partial pressure of oxygen to inspired fraction of oxygen ratio. § EELV is expressed as volume increment from the PEEP ICU level *p<0.05 compared to PEEP ICU (p < 0.05); # p<0.05 compared to PEEP INCREMENTAL
