Ultrasound may predict ventilator weaning failure in ICU patients

This study looks at whether a special ultrasound test, called VExUS, can predict which ICU patients will struggle when doctors try to remove their breathing tube. About 350 adults who have been on a ventilator for more than 48 hours will have an ultrasound before a breathing trial. The goal is to see if fluid buildup in the body, detected by ultrasound, can forecast weaning failure. This is an observational study, meaning no changes are made to standard care, and it may help future patients by improving how doctors decide when to remove breathing support.
