ClinConnect Summary

This clinical trial is studying a method called high-flow nasal oxygenation during a process called preoxygenation, which happens before patients receive general anesthesia for surgery. The goal is to see if using high-flow nasal oxygen can help reduce a common problem called atelectasis, where part of the lung collapses, especially in obese patients. This condition can lead to breathing difficulties after surgery, so finding effective ways to prevent it is important.

To participate in this study, you need to be an adult who is scheduled for surgery lasting at least two hours and has a body mass index (BMI) of 30 or more. You will need to provide consent to take part. If you have certain medical conditions, such as severe heart or lung disease, or if you've had previous problems with breathing or surgeries in the head and neck area, you may not be eligible. Participants will receive high-flow nasal oxygen during the preoxygenation phase, and your progress will be monitored to help researchers understand the treatment's effectiveness. If you are interested in joining, the trial is currently recruiting participants.
