A pulmonary embolism is a blood clot that travels from another part of the body to an artery in the lungs, suddenly stopping blood flow. These clots usually travel from the legs but can come from anywhere in the body.
Restricting blood flow to the lungs, a pulmonary embolism lowers oxygen levels in the lungs and increases blood pressure in your pulmonary arteries. Without quick treatment, a pulmonary embolism can cause heart or lung damage and can even be life-threatening.
