Abstract Introduction The aim of the study was to test the hypothesis that a pumpless arteriovenous extracorporeal membrane oxygenator interventional lung assist ILA does not significantly improve oxygenation in a lavage model of acute lung injury. Methods The study was designed as a prospective experimental study. The experiments were performed on seven pigs 48-60 kg body weight . The pigs were anesthetized and mechanically ventilated. Both femoral arteries and one femoral vein were cannulated and connected with ILA. Acute lung injury was induced by repeated bronchoalveolar lavage until the arterial partial pressure of O2 was lower than 100 Torr for at least 30 minutes during ventilation with 100 O2. Results ILA was applied with different blood flow rates through either one or both femoral arteries. Measurements were repeated at different degrees of pulmonary gas exchange impairment with the pulmonary venous admixture ranging from to
