Figure 2From: Mechanical ventilation with heliox in an animal model of acute respiratory distress syndromeTotal histology score in an animal model of LPS-induced lung injury and healthy controls. The model was ventilated with heliox or oxygen-in-air (N = 8 per group). Healthy animals are marked by open dots and LPS animals by black dots. Data are mean ± SD. *P < 0.05; **P < 0.01.Back to article page
