Ultrasound of belly fat and lung pressure in spine surgery

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 uses ultrasound (a non-painful scanning method) to measure how well the diaphragm works around the time of surgery. It aims to learn whether diaphragm changes during surgery relate to breathing problems, especially in people undergoing abdominal, pelvic, or vascular operations.

This study uses lung ultrasound to see how different positions during surgery affect lung collapse after general anesthesia. It may help find ways to reduce breathing problems after an operation.

This study checks how reliable ultrasound is at measuring diaphragm movement in people having planned surgery. If you are having an elective surgery, you may be able to join and help researchers see if ultrasound is a consistent tool.

This study uses ultrasound images of the lungs before surgery to predict which patients might develop breathing problems afterward. It helps doctors understand how a simple scan can warn about complications, so they can prepare better care after your operation.

This trial tests a new way to set oxygen levels during spine surgery while lying face down. The goal is to see if it can prevent small air sacs in the lungs from collapsing after surgery, which may help you breathe easier.
