Comparison of the Time to Reach End-Tidal Oxygen Value of 90 and Oxygen Reserve Index Decline Times During Preoxygenation in Sarcopenic and Non-Sarcopenic Patients

The purpose of this study is to compare the time required to reach an end-tidal oxygen (EtO2) value of 90% and the time until the Oxygen Reserve Index (ORI) drops below 0.55 during preoxygenation in sarcopenic and non-sarcopenic patients. The study aims to investigate the impact of sarcopenia on the oxygenation process.
