What is a pulmonary embolus?

Blood clot

Blood
A pulmonary embolus is an object, usually a blood clot, that has traveled from another part of your body to the lung, via the blood stream. Most PEs lodge in the branches of the pulmonary atery. Untreated (or even treated) PEs can be fatal or lead to significant injury.

Dr. Ted King answered:

What are the tests for pulmonary embolus?

PE testing

Embolus
If your history is strongly suggestive that you might have a pulmonary embolism-PE, then a blood test called a d-dimer might be ordered. If that is low, you don't have a clot. If high, the gold standard of testing for a PE is a spiral cat scan of the lungs with infusion. Ventilation-perfusion scans and pulmonary angiography are done infrequently these days as long as a CT scan can be done.

How much does a pulmonary embolus hurt?

Varies

Small emboli may cause no symptoms, but larger ones almost always cause significant distress from shortness of breath. Pleurisy is very common and very uncomfortable.

How do a pulmonary embolus and pulmonary infarct differ?

Embolus and infarct

Infarction
Embolus is clot migration to pulmonary artery causing clinical symptoms. Lung infarct means death or necrosis of lung tissue. Pulmonary embolus is only occasionally associated with infarct due to double blood supply.

Dr. Ted King answered:

What are the major signs and symptoms of pulmonary embolus?

PE symptoms

Embolus
Some patients with pulmonary embolism have no symptoms whatsoever. So, it is possible to have one and not know it, especially if it is a small clot. If the clot is big enough, most patients will have sudden onset of shortness of breath, chest pain that worsens when breathing deeply, a cough, and a fast pulse. Sometimes people with a PE are lightheaded, dizzy, clammy, and sweaty.

How long does pain from pulmonary embolus last?

Depends

Pleurisy
can be short, just at the time the embolus occurs, or can be longer if the patient develops pleurisy after the embolus.
