. An embolism is the lodging of an embolus, a blockage-causing piece of material, inside a blood vessel.

Pulmonary embolism is a blockage in one of the pulmonary arteries in the lungs. The pulmonary emboli result from thrombus or blood clot, amniotic fluid, fat, and air.

In this lecture, Dr. Ana Crawford presents the definition, etiology, and pathophysiology of pulmonary emboli.

She describes various etiologies of pulmonary emboli while discussing their effects on gas exchange and hemodynamics.
She addresses how pulmonary emboli can present clinically.
She outlines how an embolus will move from the lower systems and end up in the lungs.

Virchow's triad includes venous stasis, endothelial injury, and hypercoagulable state.

Venous thrombi (DVTs) can become emboli. The thrombi lodge in the lungs and disrupt the pulmonary perfusion and gaseous exchange in the lungs.

Pulmonary emboli increase dead space. V/Q mismatch, both physiological and pathological, is presented in the light of pulmonary emboli.
The causes and risk factors of fat embolism, amniotic fluid embolism, and air embolism have discussed.
