Cerebral cortical oxygenation changes during OPCAB surgery Sudath P Talpahewa, FRCS, Raimondo Ascione, MD, Gianni D Angelini, FRCS, A.Timothy Lovell, FRCA The Annals of Thoracic Surgery Volume 76, Issue 5, Pages 1516-1522 (November 2003) DOI: 10.1016/S0003-4975(03)01072-5

Fig 1 Typical cerebral NIR parameter changes seen during OPCAB surgery. The two boxed areas identify the Trendelenburg positioning and right lateral tilting of the operating table during Cx and PDA grafting. (A = lifting heart; B = grafting of obtuse marginal; C = grafting of obtuse marginal completed; [Cyt-Ox] = cytochrome oxidase; Cx = circumflex artery; D = grafting of PDA; E = grafting of PDA completed; F = grafting of LAD; G = grafting of LAD completed; [HHb] = deoxyhemoglobin; LAD = left anterior descending artery; NIR = near infrared; [O2Hb] = oxyhemoglobin; OPCAB = off-pump coronary artery bypass; THI = tissue hemoglobin index; TOI = tissue oxygenation index.)
