Figure 4.

Mean arterial partial pressure of oxygen (PaO2) vs. mean ventilation (A, r ²  = 0.7, P  = 0.16), mean arterial partial pressure of oxygen (PaO2) vs. mean global ventilation perfusion ratio (B, r ²  = 0.92, P  = 0.04, y  = 21 x  + 3.6), mean alveolar-arterial oxygen partial pressure gradient vs. mean of mean pulmonary artery pressure (C, r ²  = 0.97, P  = 0.017, y  = 1.3 x  + 8.9), mean alveolar-arterial oxygen partial pressure gradient vs. mean pulmonary vascular resistance (D, r ²  = 0.95, P  = 0.024, y  = 11.9 x – 6.5), mean pulmonary artery pressure vs. mean pulmonary artery wedge pressure (E, r ²  = 0.77, P  = 0.004, y  = 1.5 x  + 8.4), mean pulmonary artery pressure vs. cardiac output (F, r ²  = 0.47, P  = 0.003, y  = 9.5 x – 17.2). Data were averaged for 12 goats and r is Pearson’s correlation coefficient.
