Here's a breakdown:
* Pulmonary Embolism (PE): A blockage in one or more of the pulmonary arteries in the lungs. These arteries carry blood from the heart to the lungs.
* Cause: The blockage is usually caused by a blood clot that travels from the legs (deep vein thrombosis or DVT) or other parts of the body to the lungs.
* Symptoms: Symptoms can vary greatly depending on the size and location of the clot. Some common signs include:
* Shortness of breath
* Chest pain
* Coughing
* Rapid heartbeat
* Dizziness
* Swelling in the legs
* Diagnosis: Diagnosis is typically done through imaging tests like CT scans, X-rays, or a ventilation-perfusion scan.
* Treatment: Treatment involves medications to thin the blood and prevent further clots, and in some cases, surgery may be necessary to remove the clot.
It's important to note: If you experience any of the above symptoms, seek medical attention immediately. Pulmonary embolism can be life-threatening if not treated promptly.
