Infection-induced lung injury is worsened after renal buffering of hypercapnic acidosis

Abstract

Our results demonstrate that infection-induced injury in vivo is worsened after renal buffering of hypercapnic acidosis independently of any changes in tidal volume. These findings have important implications for our understanding of the pathogenesis of infection-induced lung injury during the use protective ventilation strategies that permits buffered hypercapnia and during infective exacerbations of chronic lung diseases associated with sustained hypercapnia.
