Testing how different oxygen levels affect surgery outcomes
Part of Heart & circulation, Injuries & trauma clinical trials.
This trial studies whether giving higher or lower oxygen during general anesthesia changes heart and lung outcomes after planned (non-emergency) non-heart surgery. It may help doctors choose safer oxygen settings during surgery for people at higher risk for heart problems.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You can sign a consent form and are having planned, non-emergency non-heart surgery under general anesthesia
- Your surgery is “elective/non-emergent” and not happening inside 12 hours of being scheduled
- You must have either known coronary artery disease or at least two heart risk factors, plus a high or intermediate surgical risk procedure
- Your oxygen level before surgery must be 90% or higher on room air
- You must not have had a major heart event in the last 30 days
- You should not have severe lung problems or require oxygen therapy at home

This study tests whether using a lower oxygen level during lung surgery with one lung collapsed is safe when guided by a brain oxygen monitor. It may help reduce lung injury while keeping the brain healthy.
This trial tests whether a lower or higher oxygen concentration during surgery can help protect lung function in older adults. It focuses on people 65 and older having laparoscopic gastrointestinal surgery.
This trial tests how the amount of oxygen given before removing the breathing tube after abdominal surgery affects oxygen levels after the tube is removed. It may help prevent low oxygen levels while you recover in the post-anesthesia care unit.
This study looks at how different oxygen levels during surgery affect recovery. It includes adults having surgery with a breathing tube, but excludes people having open-heart surgery, certain lung procedures, or who have had bleomycin chemotherapy.
This study is testing whether adjusting the amount of oxygen given during and after surgery can help reduce lung complications in people having lung surgery with a special breathing tube. The goal is to find a safer oxygen level that might keep your lungs healthier.
This study compares how much oxygen is needed and how well oxygen levels stay in a safe range after heart surgery in the ICU. It also tests whether using different oxygen monitors affects oxygen flow and oxygenation.
