A simple breath: could guided breathing calm heart failure symptoms?

This trial tests whether nurse-guided breathing exercises can reduce shortness of breath and anxiety in people with advanced heart failure who come to the emergency department. Participants are randomly assigned to receive either standard care plus guided diaphragmatic and pursed-lip breathing exercises, or standard care alone. Researchers measure changes in breathing difficulty and psychological distress to see if this low-cost, drug-free approach offers extra relief.
