	Pulmonary Embolism-Topic Overview
		Pulmonary embolism is the sudden blockage of an artery in the lung.
		The most common cause of pulmonary embolism is a blood clot that forms in a deep vein in your leg, breaks loose, travels to the lungs, and becomes trapped in one of the smaller lung arteries.
		To prevent future pulmonary embolism, a filter may be placed inside the large central vein (vena cava) of the body to trap clots and prevent them from traveling to the lungs.

	Embolism - Wikipedia, the free encyclopedia
		In medicine, an embolism occurs when an object (the embolus, plural emboli) migrates from one part of the body (through circulation) and cause(s) a blockage (occlusion) of a blood vessel in another part of the body.
		This forms a pulmonary embolism that can be a complication of deep-vein thrombosis.
		In the rare cases where there is a congenital hole in the heart (or some other abnormality of the circulation), it is possible that an embolus from a systemic vein can cross into the arterial system and land anywhere in the body.

	Embolism \| AHealthyMe.com
		In a pulmonary embolism, a common illness, blood flow is blocked at a pulmonary artery.
		A pulmonary embolism is caused by blood clots that travel through the blood stream to the lungs and block a pulmonary artery.
		Embolism can be prevented in high risk patients through antithrombotic drugs such as heparin, venous interruption, gradient elastic stockings, and intermittent pneumatic compression of the legs.

	Postgraduate Medicine: Early intervention in massive pulmonary embolism
		Massive pulmonary embolism is defined as pulmonary embolism accompanied by hypotension or shock, severe hypoxemic respiratory failure, acute right-sided heart dysfunction, or obstruction of the pulmonary vasculature that exceeds 50% as demonstrated by angiogram or ventilation-perfusion (V/Q) scan.
		Pulmonary embolism causes profound alterations in hemodynamics and gas exchange, the extent of which depends on the severity of pulmonary vascular obstruction and the prior state of the heart and lungs.
		The electrocardiogram is abnormal in 75% to 90% of patients with pulmonary embolism.

	The Analyst - Internet Health Report: Condition: Pulmonary Embolism
		Pulmonary embolism, a severe and life-threatening condition, is caused when the pulmonary artery is blocked by foreign matter such as a blood clot (thrombus), fat, air or tumor tissue.
		Signs and symptoms of pulmonary embolism may be similar to those of a heart attack or a lung disorder such as pneumonia.

	s031022a - Pulmonary Embolism
		Abstract: Pulmonary embolism (PE) is a common disorder that is accompanied by significant morbidity and mortality.
		The proportional reduction in the odds of suffering a deep venous thrombosis was roughly the same in patients having general surgery, traumatic orthopaedic surgery, and elective orthopaedic surgery (and in medical patients who were at increased risk of thromboembolism).
		For pulmonary embolism the numbers affected were smaller, but again the reductions were highly significant both in general surgery (16 (0.5%) v 58 (1.7%) pulmonary emboli; 2P < 0.0001) and in orthopaedic surgery (28 (2.7%) v 63 (6.1%) pulmonary emboli; 2P < 0.0002).

	► Arterial embolism
		This is caused when the artery that supplies the blood to that organ or body part is blocked by an embolus (blood clot or atherosclerotic plaque) that has moved in the bloodstream from its point of origin to a new location.
		Arterial embolism may be caused by a single embolus or multiple emboli.
		If an embolism involves the arteries supplying blood flow to the lungs, it is called not arterial embolism, but a pulmonary embolism, and it is a different condition (i.e., clots originated in the veins, not the arteries).

	Pulmonary embolism
		Pulmonary embolism is an obstruction of a blood vessel in the lungs, usually due to a blood clot, which blocks a coronary artery.
		Pulmonary embolism is caused by emboli that travel through the blood stream to the lungs and block a pulmonary artery.
		Pulmonary embolism can be diagnosed through the patient's history, a physical exam, and diagnostic tests including chest x ray, lung scan, pulmonary angiography, electrocardiography, arterial blood gas measurements, and leg vein ultrasonography or venography.

	Veins1.com - Arterial Embolism
		In many cases, an arterial embolism is caused by a blood clot that forms in the heart during abnormal heart pumping (arrhythmia) or after a heart attack.
		In a pulmonary embolism, one of the most dangerous types of embolism, the embolus lodges itself in the pulmonary artery on its way to the lungs, potentially resulting in lung tissue damage (infarction) as well as fluid build-up in the lungs.
		For pulmonary embolisms, chest x-rays are effective, and tests of lung function may point to embolism as an underlying cause of breathing difficulty or other pulmonary problems.

		A large pulmonary embolism may be relatively easy for a doctor to diagnose, especially when there are obvious preconditions, such as signs of a blood clot in a leg.
		Hospitalized people at high risk of developing pulmonary embolism (such as those with heart failure, an acute myocardial infarction, chronic lung disease, obesity, a stroke or other neurologic problem or who have had clots in the past) benefit from small doses of heparin even if they are not undergoing surgery.

		Morbidity and mortality from air embolism are directly related to the size of the embolus and the rate of entry.
		The patient should be hydrated to increase CVP, which decreases the risk of embolism, and to increase LAP, which minimizes the risk of paradoxical embolism to the left side of the circulation.

	American Family Physician: Controversies in Pulmonary Embolism and Deep Venous Thrombosis
		Among those in whom the condition is diagnosed, 2 percent die within the first day and 10 percent have recurrent pulmonary embolism; the death rate among the latter group is 45 percent.1 Thus, suspicion of pulmonary embolism and its prevention are critically important, even while consensus on diagnosis and optimal treatment is not at hand.
		Fortunately, among patients in whom pulmonary embolism was suspected and the lower extremity ultrasound examination was abnormal, the diagnosis was proved (high-probability lung scan or pulmonary arteriogram) in 90 percent.
		Overall, strategies that focus on the legs to diagnose pulmonary embolism will be helpful in patients with positive ultrasound examinations-perhaps 13 percent of patients who present with suspected pulmonary embolism.9 A negative leg study does not exclude pulmonary embolism in the remaining 87 percent of patients.
