This restricts blood menstruum to the lungs, lowers oxygen levels in the lungs and increases blood pressure in the pulmonary arteries.

If a clot develops in a vein and information technology stays there, information technology's called a thrombus. If the clot detaches from the wall of the vein and travels to another part of your trunk, information technology's called an embolus.

If PEs are not treated quickly, they can crusade heart or lung impairment and fifty-fifty decease.

Who is at adventure of developing a blood clot?

People at take chances for developing a blood clot are those who:

Have been inactive or immobile for long periods of time due to bed residual or surgery.
Have a personal or family history of a blood clotting disorder, such as deep vein thrombosis (DVT) or pulmonary embolism (PE).
Have a history of cancer or are receiving chemotherapy.
Sit for prolonged periods.

People at risk for developing a pulmonary embolism include those who:

Are inactive for long periods of fourth dimension while traveling via motor vehicle, train or plane.

Take recently had trauma or injury to a vein, possibly subsequently a recent surgery, fracture or due to varicose veins.
Are pregnant or accept given birth in the previous 6 weeks.

When veins accept been injured, such as from a fracture or surgery (peculiarly in the pelvis, hip, knee or leg).
As a result of some other medical condition, such as cardiovascular disease (including congestive heart failure, atrial fibrillation and heart assault) or stroke.
When clotting factors in the blood are increased, elevated, or in some cases, lowered. Elevated clotting factors can occur with some types of cancer or in some women taking hormone replacement therapy or birth control pills. Abnormal or depression clotting factors may as well occur every bit a result of hereditary conditions.

Diagnosis and Tests

How is a pulmonary embolism detected?

Pulmonary embolism is usually detected through the following tests:

Computed tomography (CT) browse.
Lung browse.
Blood tests (including the D-dimer test).
Pulmonary angiogram.
Ultrasound of the leg -- helps to identify blood clots in patients who cannot have an X-ray due to dye allergies or who are too sick to go out their hospital room.
Magnetic resonance imaging (MRI) of the legs or lungs.

Anticoagulant medications include warfarin (Coumadin®), heparin, depression-molecular weight heparin (such as Lovenox® or Dalteparin®) and fondaparinux (Arixtra®).

Warfarin comes in tablet class and is taken orally (by mouth).
Heparin is a liquid medication and is given either through an intravenous (IV) line that delivers medication directly into the vein, or by subcutaneous (nether the skin) injections given in the hospital.
