This study looked at whether having too much or too little oxygen after heart surgery raises the chance of delirium (sudden confusion). Researchers followed 1000 patients in the ICU after cardiac surgery. The goal was to understand how oxygen levels impact recovery and brain func…

This study looked at 119 adults to find out whether using 100% oxygen or 50% oxygen during breathing tube removal after general anesthesia leads to fewer drops in blood oxygen levels. The goal is to improve safety and reduce complications like low oxygen or collapsed lungs. The r…

This study tested whether a special oxygen monitor (Oxygen Reserve Index) can help prevent lung collapse (atelectasis) in adults having robotic surgery. 58 patients were monitored during surgery, and their lungs were checked with ultrasound afterward. The goal was to see if this …

This study looked at 56 varicose vein patients having spinal anesthesia to see how the level of numbness affects their need for extra oxygen. Researchers used a new tool called the Oxygen Reserve Index (ORi) that can warn of low oxygen earlier than standard monitors. The goal was…

This study looked at whether using a tool 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 standard care or ORI-guided oxygen levels. Researche…

This study looked at how giving more or less oxygen during laparoscopic lower abdominal surgery affects stress and inflammation in the body. 76 adults having planned surgery were randomly assigned to receive either normal oxygen or extra oxygen during the procedure. Researchers m…
