Fig. 2From: The Regulation of Interleukin-8 by Hypoxia in Human Macrophages—A Potential Role in the Pathogenesis of the Acute Respiratory Distress Syndrome (ARDS)Correlation between PaO2/FiO2 ratio and raised IL-8 at admission. Initial PaO2/FiO2 ratio plotted against BAL IL-8 for trauma patients (n = 41). A negative correlation was observed between reduced PaO2/FiO2 ratio and raised BAL IL-8 (r = −0.56, P < 0.001).Back to article page
