When pulmonary embolism happens in the lungs, what makes it so fatal?

When pulmonary embolism happens in the lungs, what makes it so fatal?

Several things: A massive pulmonary embolus will essentially block most of the blood flow from the right ventricle to the lungs, preventing blood from getting oxygenated while putting a huge strain on the right ventricle. Since blood is then blocked from getting to the left side of the heart, systemic blood pressure severely drops along with oxygen delivery and things rapidly go down the tubes. ...Read more

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more

If you are really concerned you should contact your primary care physician. Otherwise if you do decide to go forth, if you have any shortness of breath or lightheadedness please leave! ...Read more

Is pulmonary embolism an obstruction in the main artery to the lung?

Is pulmonary embolism an obstruction in the main artery to the lung?

Any artery: A pulmonary embolism (pe) is a clot in any of the arteries in the lungs. If the clot is large, it will lodge in one of the larger arteries, and can be fatal. If the clot is smaller, it will travel into the lung until the vessel is small enough to trap it, and may not even cause much in the way of symptoms. Any pe is serious, and the source of the clot needs to be found to prevent recurrences. ...Read more
