Doctors test quick breath check to stop harmful IV fluids

This study tested whether watching how a patient's central blood pressure changes when they take a deep breath can predict if giving them more IV fluids will help their heart pump better. Researchers worked with 68 awake, breathing patients in intensive care who already had special monitoring lines in place. The goal was to find a quick, easy way to identify patients who won't benefit from extra fluids, to avoid giving unnecessary and potentially harmful treatments.
