Ever had a patient swear it’s their lungs—but the problem’s really their heart? In this episode, we dig into cardiac dyspnea, the kind of shortness of breath that starts in the left ventricle, not the bronchi. You’ll learn how pressure backs up into the pulmonary circuit, why patients can’t lie flat without gasping, and what separates heart failure breathlessness from COPD or asthma. Perfect for paramedics who want to sharpen their clinical instincts and catch the subtle signs before the monitor does.
