Venoarterial (1) and venovenous (2) rat ECMO models with tetrapolar electrodes for BIA. A, Fluid injection line at the right femoral vein; B, A-line monitor at the left femoral artery; C, Right external jugular vein for drainage; D(a), Right common carotid artery (A), D(b) left external jugular vein (B) for perfusion; E, Bipolar electrodes for BIA at the upper trunk; F, Bipolar electrodes for BIA at the lower trunk. BIA, bioelectrical impedance analysis; ECMO, extracorporeal membrane oxygenation.
