Abbreviation:<unk><unk>  life support (ECLS) becoming a more common term<unk>  circuit that oxygenates blood and removes carbon dioxide (functions as an out-of-body lung)
Can be high flow or low flow
Similar (but not identical) to cardiopulmonary bypass machine
Requires lower levels of anticoagulation and allows longer duration of treatment (time on pump)

Can be high flow or low flow
Requires lower levels of anticoagulation and allows longer duration of treatment (time on pump)
Veno-venous (VV)
Most common
Blood drained from central vein → oxygenator → vein near RA
Supports severe respiratory failure without cardiac dysfunction
Veno-arterial (VA): can be peripheral or central
Blood drained from central vein → oxygenator → aorta
Supports cardiac failure with or without respiratory failure
Veno-pulmonary artery
Blood drained from central vein → oxygenator → pulmonary artery
Short term right ventricular/respiratory support after LVAD placement
Hybrid (VVA or VAV)
Most common
Blood drained from central vein → oxygenator → vein near RA
Supports severe respiratory failure without cardiac dysfunction
Blood drained from central vein → oxygenator → aorta
Supports cardiac failure with or without respiratory failure
Blood drained from central vein → oxygenator → pulmonary artery
Short term right ventricular/respiratory support after LVAD placement
