Oxygen therapy is the most common treatment modality for patients with hypoxemia in intensive care units, but target values for normoxemia are not clearly defined. Therefore, iatrogenic hyperoxemia is a very common situation. In intensive care units, FiO2 is usually adjusted according to hypoxia and hyperoxia is ignored in patients under mechanical ventilator support. Even though there are many side effects reported related to hyperoxemia and hyperoxemia is shown to be related to worse outcome than expected; clinicians still observe hyperoxemia frequently. Continuous ORi monitoring can be used for detecting and preventing hyperoxia. The ability to perform FiO2 titration with ORi may be an appropriate monitoring management to prevent the harmful effects of hyperoxia. In this study, it was aimed to investigate the effectiveness of ORi-guided FiO2 titration in preventing hyperoxia in patients undergoing mechanical ventilation in the intensive care unit and to determine the incidence of hyperoxia.
