Summary

This study tested three different ultrasound techniques to see how well they confirm that a breathing tube is in the right place (windpipe vs. food pipe) in 200 emergency patients. Doctors compared these methods to standard checks like carbon dioxide monitoring and listening to the chest. The goal was to find the fastest and most accurate way to ensure patient safety during emergency intubations.
