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

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 Using the 6-Minute Walk Test

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.

Inclusion Criteria:

• Patients who agree to participate in the study.
• Patients scheduled for major abdominal oncologic surgery.

Exclusion Criteria:

• Patients with severe cardiopulmonary disease.
• Patients with walking disabilities.
