Ultrasound reveals best position to avoid lung collapse during surgery

This study looks at how often small areas of the lung collapse (atelectasis) during surgery when patients lie face-up versus face-down. Researchers will use lung ultrasound, a safe and radiation-free imaging method, to check lung health right after anesthesia and just before waking up. The goal is to understand which position leads to fewer lung problems, helping doctors improve care during routine surgeries. About 80 adults having planned surgery will take part, and no experimental treatments are given.
