Doctors use simple scan to help patients breathe on their own sooner

This study aims to find a better way to predict when patients in intensive care can safely stop using a mechanical ventilator (breathing machine). Researchers will use ultrasound to measure how a patient's main breathing muscle (the diaphragm) moves and see if specific measurements can tell doctors who is ready to breathe on their own. The goal is to help patients get off the ventilator successfully the first time, avoid the need to go back on it, and potentially shorten their hospital stay.
