pulmonary embolism (PE)

A pulmonary embolism (PE) occurs when a blood clot, often originating in the deep veins of the legs or pelvis, travels through the bloodstream and blocks an artery in the lungs. This blockage can impair blood flow, leading to reduced oxygen supply to the lungs and other parts of the body. PE can cause symptoms like sudden shortness of breath, chest pain, and rapid heartbeat. It is a serious condition that requires prompt diagnosis and treatment, often with blood thinners, to prevent complications or death. Risk factors include prolonged immobility, surgery, pregnancy, and certain medical conditions.
