What is a pulmonary embolism?

ANSWER

A pulmonary embolism usually happens when a blood clot called a deep vein thrombosis, often in your leg, travels to your lungs and blocks a blood vessel. That leads to low oxygen levels in your blood. It can damage the lung and other organs and cause heart failure, too.
