Summary

This study looks at whether a special oxygen monitor (Oxygen Reserve Index) can give early warning of low oxygen levels in patients aged 65 and older having cancer surgery. Researchers will watch 44 patients during anesthesia to see if the monitor's alerts give doctors more time to act before oxygen drops too low. The goal is to improve safety for older adults during surgery.
