What does PE mean in the medical field?

In the medical field, "PE" typically stands for "pulmonary embolism," which is a condition where one or more arteries in the lungs become blocked by a blood clot. This can lead to serious complications, including respiratory distress and decreased oxygen levels in the blood. PE often arises from deep vein thrombosis (DVT), where clots form in the deep veins of the legs and travel to the lungs. Prompt diagnosis and treatment are critical for improving outcomes.
