Figure 1From: Metabolic acidosis may be as protective as hypercapnic acidosis in an ex-vivo model of severe ventilator-induced lung injury: a pilot study Effects of metabolic acidosis on VILI attenuation in the HP ventilation group, in terms of weight gain i.e. pulmonary edema formation. HPC group preparations gained significantly greater weight than their acidotic counterparts; however, both metabolic and hypercapnic acidosis had the same protective effect on weight gainBack to article page
