ClinConnect Summary

This clinical trial is studying two methods, called the Oxygen Reserve Index (ORI) and regional cerebral oxygen saturation (rcSO2), to see which one is better at spotting low oxygen levels early in obese patients. This is important because some obese individuals are more likely to experience oxygen deficiency, especially during surgery. The study aims to understand not only how effective these methods are but also if changes in ORI and rcSO2 happen at the same time in these patients.

To participate in this trial, candidates need to be aged between 18 and 75 years and have a body mass index (BMI) between 30 and 40, meaning they are considered obese. They should be scheduled for elective surgery that requires intubation (where a tube is placed in the airway to help with breathing). However, individuals with serious heart or lung problems, those outside the specified age or BMI range, or those with a higher health risk classification (ASA >3) cannot participate. If eligible, participants can expect to undergo monitoring during their surgery to help researchers gather information about which method works best for detecting low oxygen levels.
