Can ultrasound consistently measure the diaphragm? a study puts it to the test

This study looks at whether diaphragm ultrasound gives consistent results when performed by different anesthesiologists. Two doctors will each scan the diaphragm using three different methods, and their measurements will be compared to see which method is most reliable. The goal is to find a dependable way to assess diaphragm function, especially on the left side, which is often harder to image. Participants are adults having elective surgery, and the study focuses on improving measurement accuracy rather than testing a treatment.
