1 Oxygen Delivery During Cardiopulmonary Bypass and Acute Renal Failure After Coronary Operations 
Marco Ranucci, MD, Federica Romitti, MD, Giuseppe Isgrò, MD, Mauro Cotza, CCP, Simonetta Brozzi, CCP, Alessandra Boncilli, CCP, Antonio Ditta, CCP  The Annals of Thoracic Surgery  Volume 80, Issue 6, Pages (December 2005) DOI: /j.athoracsur Copyright © 2005 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Relationship (rolling deciles nonlinear regression analysis) between the lowest hematocrit and lowest oxygen delivery during cardiopulmonary bypass and the acute renal failure rate/peak postoperative serum creatinine levels.

3 Fig 2 Receiver operating characteristic curve for the three variables being identified as independent risk factors for acute renal failure. —— = lowest hematocrit on CPB; ---- = pump flow indexed; —— = oxygen delivery indexed. (CPB = cardiopulmonary bypass; DO2 = two determinants of oxygen delivery; HCT = hematocrit.)

4 Fig 3 Acute renal failure rate in the study population according to the presence of the two risk factors (low hematocrit and low oxygen delivery). The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2005 The Society of Thoracic Surgeons Terms and Conditions
