This study tested whether breathing air with low and then high oxygen before heart bypass surgery could help protect the heart from damage. 120 adults scheduled for bypass surgery took part. The approach is drug-free and aims to reduce complications after surgery.

This completed study looked at 1,000 patients who had heart surgery and were then moved to the ICU. Researchers tracked whether high or low oxygen levels increased the chance of developing delirium, a state of confusion. The goal was to understand how oxygen management might affe…

This study looked at how different oxygen levels during laparoscopic lower abdominal surgery affect stress markers in the lungs and blood. 76 adults were randomly assigned to receive either normal (35%) or high (80%) oxygen during surgery. Researchers measured changes in various …

This study tested whether giving 50% or 100% oxygen before removing a breathing tube after anesthesia leads to fewer drops in oxygen levels. 119 patients were monitored after surgery. The goal is to find the safest oxygen setting to prevent breathing problems during recovery.

This completed study looked at whether a new monitoring tool called Oxygen Reserve Index (ORi) can give earlier warning of low oxygen levels in patients having varicose vein surgery under spinal anesthesia. The study included 56 adults and compared standard oxygen monitoring with…

This study tested whether using a special oxygen monitor (Oxygen Reserve Index) during robotic surgery helps prevent lung collapse after the operation. 58 adults having robotic surgery under general anesthesia took part. Doctors measured lung health with ultrasound before and aft…

This study tested whether using a device called the Oxygen Reserve Index (ORI) to guide oxygen levels during rhinoplasty (nose job) surgery could reduce oxidative stress, a type of cell damage. Sixty healthy adults having rhinoplasty were split into two groups: one received stand…
