What is the definition of a P.E.?
A pulmonary embolism is a blockage of an artery in the lungs caused by a clot that travels through the blood stream to the lungs

- Can be caused by trauma, remember to look for it
What is the Pathophysiology of a P.E.?
- Once the clot is stuck in a lung artery, it blocks the blood from nourishing that lung. The tissues on the other sude of the blockage may die if it doesn't receive enough blood from other sources

What is Laryngitis?
- Laryngitis is an inflammation of the voice box (larynx) due to overuse, irritation or infection. Normally your vocal cords open and close smoothly, forming sounds though their movement and vibration. But laryngitis, the vocal cords become inflamed or irritated. They swell, causing distortion of the sound produced by air passing over them. As a result, the voice sound hoarse. In some cases of laryngitis, the voice can become so faint as to be undetectable. Laryngitis may be acute or chronic. Although acute laryngitis usually is nothing more than an irritation and inflammation fro a virus, persistent hoarseness can signal a more serious problem.
