Changing positions to prevent low oxygen during sedation

This study tests whether a slightly raised head-and-shoulders position (semi-recumbent) helps prevent low oxygen levels after lung surgery. If you are having a small-incision lung removal, it may help you breathe better after the operation.

This study tests whether high-flow oxygen delivered through the nose helps children breathe better during a sedated procedure to look inside their lungs. Researchers want to see if this oxygen method prevents low blood oxygen levels during the procedure.

This study tests whether changing the angle of your head and upper body during a sedated endoscopy (a camera procedure to look at your stomach) helps keep your oxygen levels stable. Researchers want to find the safest position for patients during this common procedure.

This study tracks patients who receive propofol sedation (a common sleep medication) during routine endoscopy procedures to identify which patients are more likely to experience low blood pressure or low oxygen levels. Results may help doctors predict and prevent these complications.

This study compares two ways of giving oxygen (high-flow nasal oxygen vs a face mask) to see which one keeps brain oxygen levels more stable during procedures done with sedation. If you are having a planned procedure with sedation in a non-operating room setting, this trial might help improve your safety.

This study tests a special airway device designed to keep your oxygen levels stable during sedated gastrointestinal endoscopy (a procedure to look inside your stomach or intestines while you're lightly sedated). The device may help prevent breathing problems that can happen during this type of procedure.
