Hyperoxygenated ventilation during anaesthesia

In everyday work there is frequent discussion about the desired FiO2 values for ventilators. While clear guidelines are in place for induction and extubation there are no uniform specifications or recommendations for oxygen concentration during surgery. Oxygen is by far the most widely used medication in general anaesthesia. In addition to oxygenating the body oxygen also has other positive and negative effects. The central question is what intraoperative oxygen concentration can be used to achieve the best outcome in terms of tissue oxygenation. Reducing wound infections ensuring optimal wound healing and thus reducing postoperative complications is in the interests of both patients and the disciplines involved.
