  1. Hemodynamics and oxygen consumption in lung injured lambs (surviving) supported by conventional mechanical ventilation (CMV; n = 6) or arteriovenous (AV)-extracorporeal membrane oxygenation (ECMO; n = 4) during a 6-hour period of study. Values are expressed as mean ± standard deviation. *P < 0.05, baseline (time 0) versus 2, 4, and 6 hours of study by repeated measures analysis of variance (ANOVA) followed by Dunnett multiple comparisons test. P < 0.05, CMV versus AV-ECMO groups; ANOVA followed by Bonferoni multiple comparisons test.
