  Pulmonary embolism - Wikipedia, the free encyclopedia
Pulmonary embolism is a blockage of an artery in the lungs by a blood clot, fat, air or clumped tumor cells.
By far the most common form of pulmonary embolism is a thromboembolism, which occurs when a blood clot, generally a venous thrombus, becomes dislodged from its site of formation and embolizes to the arterial blood supply of one of the lungs.
Chronic pulmonary embolism leading to pulmonary hypertension (known as chronic thromboembolic hypertension) is treated with a surgical procedure known as a pulmonary thromboendarterectomy.

 Pulmonary artery - Wikipedia, the free encyclopedia
The pulmonary arteries carry blood from the heart to the lungs.
In the human heart, the pulmonary trunk (pulmonary artery or main pulmonary artery) begins at the base of the right ventricle.
Pulmonary hypertension occurs alone and as a consequence of a number of lung diseases.

 Pulmonary hypertension
Pulmonary hypertension is a rare lung disorder characterized by increased pressure in the pulmonary artery.
Pulmonary hypertension is present when the blood pressure in the circulation of the lungs is measured at greater than 25 mm of mercury (Hg) at rest or 30 mm Hg during exercise.
Pulmonary hypertension is rarely detected during routine physical examinations and, therefore, often progresses to later stages before being diagnosed.

 Pulmonary edema   (Site not responding. Last check: 2007-10-31)
Pulmonary edema is a condition in which fluid accumulates in the lungs, usually because the heart's left ventricle does not pump adequately.
Pulmonary edema is a common complication of heart disorders, and most cases of the condition are associated with heart failure.
Sometimes pulmonary artery catheterization is performed to confirm that the patient has pulmonary edema and not a disease with similar symptoms (called adult respiratory distress syndrome or "noncardiogenic pulmonary edema").

 Pulmonary embolism
The symptoms of pulmonary embolism can vary greatly, depending on how much of your lung is involved, the size of the clot and your overall health — especially the presence or absence of underlying lung or heart disease.
Although pulmonary embolism is a leading cause of hospital deaths, it's also a serious problem for nursing home residents, who are likely to have a number of risk factors for DVT, as well as for people immobilized at home.
In a pulmonary angiogram, a flexible tube (catheter) is inserted into a large vein — usually in your groin — and threaded through your heart into the pulmonary arteries.

Persistent pulmonary hypertension of the newborn is a cardiopulmonary disorder characterized by systemic arterial hypoxemia secondary to elevated pulmonary vascular resistance with resultant shunting of pulmonary blood flow to the systemic circulation.
Because of the high pulmonary vascular resistance, blood is diverted away from the lungs through the foramen ovale and the patent ductus arteriosus into the low resistance systemic and placental circuit.
Persistent pulmonary hypertension of the newborn in a pathophysiologic syndrome that results when the pulmonary vascular resistance fails to decrease after birth, despite improved alveolar oxygenation and lung expansion.

 Pulmonary Atresia - My Child Has - Children's Hospital Boston
Pulmonary atresia (PA) is a complicated congenital (present at birth) defect that occurs when the pulmonary valve, located between the right ventricle and pulmonary artery, is not formed properly.
The pulmonary valve has three leaflets that function like a one-way door, allowing blood to flow forward into the pulmonary artery, but not backward into the right ventricle.
Pulmonary atresia occurs due to the improper development of the heart during the first eight weeks of fetal growth.

 Pulmonary Hypertension Causes, Diagnosis, Symptoms, and Treatment on MedicineNet.com
Pulmonary hypertension results from constriction, or tightening, of the blood vessels that supply blood to the lungs.
Pulmonary hypertension can be caused by diseases of the heart and the lungs, such as chronic obstructive pulmonary disease (COPD) or emphysema, failure of the left heart ventricle, recurrent pulmonary embolism (blood clots traveling from the legs or pelvic veins obstructing the pulmonary arteries), or underlying diseases such as scleroderma.
Pulmonary hypertension can also be caused by chronic low blood oxygen levels as in some patients with sleep apnea.

Pulmonary Function Tests (PFTs) reveal the degree of respiratory muscle involvement, the progression of symptoms, early recognition of reversible complications, pending respiratory failure and the need for appropriate therapy as desired by the patient.
Pulse oximetry is the best alternative to expensive, painful arterial blood gases, requiring a needle puncture, which may not reveal abnormal oxygen and carbon dioxide levels in the blood until breathing problems are advanced.
People with ALS should know why pulmonary tests are performed and the meaning of their test findings to keep informed of their respiratory status and when treatment may be needed.

 eMedicine - Pulmonary Embolism : Article by Craig Feied, MD, FACEP, FAAEM, FACPh
Background: Pulmonary embolism (PE) is an extremely common and highly lethal condition that is a leading cause of death in all age groups.
The objective components of the Wells (Canadian Pulmonary Embolism Score) criteria, for example, have been shown to have little effect on the stratification power of the criteria; virtually all of the classification power is associated with a physician's subjective prejudgment of the likelihood of PE.
Pulmonary angiography remains the criterion standard for the diagnosis of PE but is rapidly being replaced by MDCTA, since the latter modality is significantly less invasive, is easier to perform, and offers equal sensitivity and specificity.

 Pulmonary Hypertension -- familydoctor.org   (Site not responding. Last check: 2007-10-31)
"Pulmonary" means "in the lungs," and "hypertension" means "high blood pressure." Pulmonary hypertension happens when the pulmonary arteries (the vessels that carry blood from the heart to the lungs) narrow so they can't carry as much blood.
When the cause of pulmonary hypertension isn't known, the disorder is called "primary" pulmonary hypertension.
Other causes are congestive heart failure, birth defects in the heart, chronic pulmonary thromboembolism (old blood clots in the pulmonary arteries), human immunodeficiency virus (HIV) infection, and certain medicines.
