Improvement of pulmonary gas exchange in patients and animals with acute lung injury nursed in the prone position was observed in recent years. The purpose of this study was to evaluate the effects of prone and supine positions on pulmonary and cardiovascular functions following experimental chlorine gas lung injury.<\/jats:p><jats:p><jats:bold>Methods: <\/jats:bold> Twenty anesthetized and mechanically ventilated pigs were exposed to chlorine gas (400\u2003p.p.m. in air) for 20\u2003min in the supine position, then assigned randomly to ventilation in the supine or prone positions (n=10 in each group). Hemodynamics, gas exchange, lung mechanics and oxygen transport were evaluated for 5\u2003h.<\/jats:p><jats:p><jats:bold>Results: <\/jats:bold> All animals showed severe pulmonary dysfunction immediately after chlorine gassing with a threefold increase in pulmonary vascular resistance index, a drop in arterial oxygenation (12.3\u00b11.3\u2003kPa to 5.4\u00b10.7\u2003kPa) and a fall in lung\u2010thorax compliance (22\u00b11\u2003ml\u2003cmH<jats:sub>2<\/jats:sub>O<jats:sup>\u22121<\/jats:sup> to 8\u00b12\u2003ml\u2003cmH<jats:sub>2<\/jats:sub>O<jats:sup>\u22121<\/jats:sup>).
