Fig 1 Schematic layout of the dual-vent deairing apparatus (see text for details). (CPB = cardiopulmonary bypass; LV = left ventricle; RA = right atrium; SVC = superior vena cava.) The Annals of Thoracic Surgery 1998 66, 785-791DOI: (10.1016/S0003-4975(98)00572-4)
Fig 2 Index of microembolic activity (IMA) during each phase of the operation in group 1. (A = 5-minute period before placement of the first sutures; B = end of A to the beginning of cardiopulmonary bypass [CPB]; C = 10 minutes following the beginning of CPB; D = from C to the beginning of rewarming; E = beginning of rewarming to 34°C; F = 34°C to aortic declamping; G = aortic declamping until withdrawal of CPB; H = 20 minutes after CPB withdrawal.)

Fig 3 Index of mircroembolic activity (IMA) recorded after aortic declamping in all groups. (group 1 = conventional deairing; group 1a = surgeon conventional deairing with lowest median IMA; group 1b = F.P.M. conventional deairing; group 2 = dual-vent technique; group 3 = nonvented coronary artery bypass grafting.)
