Pulmonary Embolism
What is it?
A blood clot in the lung.
It occurs when a clot, usually in the leg or pelvis, breaks free and gets stuck in a lung artery (pulmonary artery). The clot interrupts blood flow, making it more difficult for your lungs to provide oxygen to the rest of your body.
Symptoms:
-
Sudden, sharp chest pain often with shortness of breath
-
Sudden, unexplained shortness of breath, even without pain
-
Cough that may produce blood-streaked spit
-
Rapid heartbeat with shortness of breath
-
Fainting
-
Severe anxiety
-
Unexplained sweating
-
Swelling of one leg only, caused by a blood clot in the leg
Pulmonary embolism can be life-threatening. If you have symptoms of a pulmonary embolism, seek emergency medical help immediately.
