Summary

In obese patients, the risk of perioperative complications such as rapid desaturation, atelectasis, difficult mask ventilation, difficult intubation, and hypoxia is higher compared to the normal population. Therefore, preoxygenation is even more critical in the obese patient group. In clinical practice, ETO2 is used as a practical indicator to evaluate sufficient oxygenation during preoxygenation. The Oxygen Reserve Index (ORiⓇ) is a new oxygenation monitoring parameter that is continuously and non-invasively measured by a specialized pulse oximetry device (Masimo, Irvine, CA).The primary objective of the investigators was to observe the correlation between ORIⓇ monitoring and ETO₂ during preoxygenation in obese patients.The secondary objective of the investigators was to evaluate the correlation of ORIⓇ with SpO₂ and PaO₂ in this patient population.
