Özet

Background: The inspiratory oxygen fraction (FiO(2)) is usually set between 60% and 100% during conventional extracorporeal circulation (ECC). However, this strategy causes partial oxygen pressure (PaO2) to reach hyperoxemic levels (>180 mmHg). During anesthetic management of cardiothoracic surgery it is important to keep PaO2 levels between 80-180 mmHg. The aim of this study was to assess whether adjusting FiO(2) levels in accordance with body temperature and body surface area (BSA) during ECC is an effective method for maintaining normoxemic PaO2 during cardiac surgery.
