Finding the best air pressure for facemask breathing in severe obesity
Part of Lungs & breathing clinical trials.
This trial tests different air pressure levels during facemask breathing before surgery to find the one that avoids air going into the stomach while still providing enough oxygen. It is for people with a BMI of 40 or higher who are having planned surgery under general anesthesia.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 65 years old
- You are scheduled for planned (non-emergency) surgery under general anesthesia
- Your body mass index (BMI) is 40 or higher
- You have no history of stomach surgery, narrowed food pipe, or hiatal hernia
- You have not had food for at least 6 hours and clear liquids for at least 2 hours before surgery

This trial tests whether a personalized breathing setting during surgery can lower the risk of lung complications after weight-loss surgery. If you have a high risk of lung issues, you may be eligible.
This trial tests a personalized way of setting the breathing machine during weight-loss surgery to reduce lung stress. It compares a tailored approach with standard care in people with obesity.
This trial tests two different ways to keep your lungs inflated with air during bariatric (weight-loss) surgery. Researchers want to see which method helps you breathe better and recover faster after your procedure.
This study tests whether changing your head and body position helps with breathing mask ventilation before surgery in people with obesity.
This study tests the best air pressure to use with a mask to keep air out of the stomach when you first go to sleep for surgery. It helps make anesthesia safer and more comfortable for you.
This study tests different ways of using a breathing machine (ventilator) during laparoscopic surgery in people with obesity. The goal is to find a safer and more effective ventilation method for this group.
