This study looked at whether using a special oxygen monitor (Oxygen Reserve Index) during robotic surgery can help prevent the lungs from partially collapsing after the operation. Fifty-eight adults having robotic surgery took part. The researchers measured lung health with ultra…

This study looked at whether using a special monitor called Oxygen Reserve Index (ORI) during nose surgery can prevent giving patients too much oxygen, which can cause cell stress. Sixty adults having rhinoplasty were randomly assigned to have oxygen levels guided by ORI or stand…

This study measured how giving higher or normal oxygen levels during laparoscopic lower abdominal surgery affects certain substances in the blood related to lung stress, inflammation, and blood vessel health. 76 adults took part, and researchers compared the two oxygen strategies…

This study involved 56 patients having spinal anesthesia for varicose vein surgery. Researchers tested a new monitoring tool called Oxygen Reserve Index (ORi) that can warn of low oxygen earlier than standard methods. The goal was to see how ORi relates to the level of numbness a…

This study tested whether giving 50% or 100% oxygen during breathing tube removal after general anesthesia leads to fewer drops in oxygen levels. 119 adults having various surgeries took part. The goal was to find the safest oxygen amount to prevent complications like low oxygen …

This study examined whether high or low oxygen levels after heart surgery increase the risk of delirium (sudden confusion). Researchers monitored 1000 patients in the ICU after cardiac surgery. The goal was to understand the relationship, not to test a new treatment.
