Fig. 7From: Intravenous superoxide dismutase as a protective agent to prevent impairment of lung function induced by high tidal volume ventilationHourly measured serum NO during LTV (white) and HTV ventilation (black) and HTV ventilation with SOD administration (grey). Both LTV and HTV ventilation decreased serum NO. LTV ventilation decreased serum NO primarily during the first 2Â h of ventilation (PÂ <Â 0.05), whereas HTV ventilation decreased serum NO throughout most of the 5Â h of ventilation (PÂ <Â 0.05, except at 4Â h). Notably, SOD administration monotonically increased serum NO level during the course of HTV ventilationBack to article page
