Summary

Oxygen therapy is the most common treatment modality for patients with hypoxemia, but target values for normoxemia are not clearly defined. Therefore, iatrogenic hyperoxemia is a very common situation. 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. Oxygen reserve index (ORi™) (Masimo Corp., Irvine, USA) can guide clinicians in detection of hyperoxia. ORi is a parameter which can evaluate partial pressure of oxygen (PaO2) rating from 0 to 1. There are growing evidences in ORi that it might be helpful to reduce hyperoxia in general anesthesia. 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, in patients who underwent major abdominal surgery; It was aimed to investigate the effectiveness of ORi-guided FiO2 titration in preventing hyperoxia.

Interventions

Type	Name	Description
PROCEDURE	Titration of fraction of inspired oxygen (FiO2) guided by ORI and oxygen saturation	* FiO2 will be titrated by reducing 10% if Ori\>0.01 and oxygen saturation ≥ 98% until Ori is 0.00. * FiO2 will not be changed if Ori is 0.00 and %95\<oxygen saturation≤%98 * FiO2 will be increased by 10% if oxygen saturation \<95 or PaO2\<60 mmHg
PROCEDURE	SpO2 (oxygen saturation)	Fraction of inspired oxygen (FiO2) is titrated guided by oxygen saturation in that range; %95\<oxygen saturation≤%98
