Pulmonary Embolism
Pulmonary embolism (PE) is a life-threatening condition that occurs when a blood clot, usually from the deep veins of the legs or pelvis, travels to the lungs and blocks a pulmonary artery. This obstruction can severely reduce oxygen flow to the lungs and other vital organs, leading to sudden death if not promptly diagnosed and treated. Unfortunately, PE is often misdiagnosed or not treated in time, making it a leading cause of preventable death in the United States.
