Figure 2. Arterial blood oxygenation 5.5 h after exposure to 800 ppm chlorine for 4 min.
Arterial blood gas analysis was performed in rabbits 5.5 h after exposure to 800 ppm chlorine or air for 4 min. A) Ratio of the partial pressure of oxygen (PaO2) to the fraction of inspired oxygen (FiO2). B) Alveolar-arterial (A-a) gradient. a, p<0.05 vs. air. n=9–10 rabbits/group.
