The ABG shunt was 3.5 mm in diameter with a 1.2-mm diameter circular nozzle.

ABG = assisted bidirectional Glenn; BDG = bidirectional Glenn; C = central shunt; CO = mean cardiac output; HL = ventricular load; mBT = modified Blalock-Taussig shunt; OD = systemic oxygen delivery; Pao = aortic average pressure; Ppulm = mean pulmonary artery pressure; Psvc = superior vena caval average pressure; Psys = systolic average pressure; PVR = pulmonary vascular resistance; Qp = pulmonary flow rate; Qs = systemic flow rate; Qp/Qs = pulmonary to systemic flow ratio; Qshunt = flow rate through the ABG shunt; Satao = oxygen saturation in the aorta.
