There are studies on higher mortality in burn patients with inhalation injury. Cancio 2004 found out, that inhalation injuries were linked to higher volumina of fluids applied, only when artificially ventilated. Could it be possible that the higher mortality of inhalation injuries at least partially is linked to the fact of hyperbaric ventilation, increasing the level of natriuretic peptide and causing capillary leakage in a higher amount than in non-ventilated, followed by higher needs of fluid?
