Diseases & Conditions A-Z List - «P»:

  1. Pulmonary angiography Pulmonary angiography
    A pulmonary angiography is a procedure that uses a special dye (contrast material) and x-rays to see how blood flows through the lungs. How the Test is Performed This test is done in a hospital. You will be asked to lie on an x-ray table. Electrocardiogram (ECG) leads are taped to your arms and leg...
  2. Pulmonary arteriovenous fistula Pulmonary arteriovenous fistula
    Pulmonary arteriovenous fistula is a condition in which an abnormal connection (fistula) develops between an artery and vein in the lungs. As a result, blood passes through the lungs without receiving enough oxygen. Causes Pulmonary arteriovenous fistulas are usually the result of a genetic disease...
  3. Pulmonary aspergilloma (mycetoma) Pulmonary aspergilloma (mycetoma)
    Pulmonary aspergilloma is a mass caused by a fungal infection that usually grows in lung cavities. It can also appear in the brain, kidney, or other organs. Causes Aspergillomas are formed when the fungus aspergillus grows in a clump in a lung cavity, or invades previously healthy tissue, causing a...
  4. Pulmonary atresia Pulmonary atresia
    Pulmonary atresia is a form of congenital heart disease in which the pulmonary valve does not form properly. The pulmonary valve is an opening on the right side of the heart that regulates blood flow from the right ventricle (right side pumping chamber) to the lungs. In pulmonary atresia, a solid sh...
  5. Pulmonary edema Pulmonary edema
    Pulmonary edema is an abnormal build up of fluid in the air sacs of the lungs, which leads to shortness of breath Causes Pulmonary edema is usually caused by heart failure. As the heart fails, pressure in the veins going through the lungs starts to rise. As the heart fails, pressure in the veins go...
  6. Pulmonary embolus Pulmonary embolus
    A pulmonary embolus is a blockage of an artery in the lungs by fat, air, a blood clot, or tumor cells. Causes A pulmonary embolus is most often caused by a blood clot in a vein, especially a vein in the leg or in the pelvis (hip area). The most common cause is a blood clot in one of the deep veins ...
  7. Pulmonary function tests Pulmonary function tests
    Pulmonary function tests are a group of tests that measure how well the lungs take in and release air and how well they move gases such as oxygen from the atmosphere into the body's circulation. How the Test is Performed In a spirometry test, you breathe into a mouthpiece that is connected to an in...
  8. Pulmonary hypertension Pulmonary hypertension
    Pulmonary hypertension is abnormally high blood pressure in the arteries of the lungs. It makes the right side of the heart need to work harder than normal. Causes The right side of the heart pumps blood through the lungs, where it can receive oxygen. When the small arteries (blood vessels) of the ...
  9. Pulmonary nocardiosis Pulmonary nocardiosis
    Pulmonary nocardiosis is an infection of the lung with the bacteria, Nocardia asteroides. Causes Nocardia infection develops when you breathe in (inhale) the bacteria. The infection causes pneumonia -like symptoms. The infection can spread to any part of the body. People at highest risk for nocardi...
  10. Pulmonary tuberculosis Pulmonary tuberculosis
    Pulmonary tuberculosis (TB) is a contagious bacterial infection that mainly involves the lungs, but may spread to other organs. Causes Pulmonary tuberculosis (TB) is caused by the bacteria Mycobacterium tuberculosis (M. tuberculosis). You can get TB by breathing in air droplets from a cough or snee...
  11. Pulmonary valve stenosis Pulmonary valve stenosis
    Pulmonary valve stenosis is a heart valve disorder that involves the pulmonary valve. This valve separates the right ventricle (one of the chambers in the heart) and the pulmonary artery. The pulmonary artery carries oxygen-rich blood to the lungs. Stenosis occurs when the valve cannot open wide eno...
  12. Pulmonary veno-occlusive disease Pulmonary veno-occlusive disease
    Pulmonary veno-occlusive disease is an extremely rare form of high blood pressure in the lung area. See also: Primary pulmonary hypertension Causes In most cases, the cause of pulmonary veno-occlusive disease is unknown. The condition may be related to a viral infection. It may occur as a complica...
  13. Pulmonary ventilation/perfusion scan Pulmonary ventilation/perfusion scan
    A pulmonary ventilation/perfusion scan is a pair of nuclear scan tests. These tests use inhaled and injected radioactive material (radioisotopes) to measure breathing (ventilation) and circulation (perfusion) in all areas of the lungs. How the Test is Performed A pulmonary ventilation/perfusion sca...
  14. Pulse Pulse
    The pulse is the number of heartbeats per minute. How the Test is Performed The pulse is measured at the: Back of the knees Groin Neck Temple Top or inner side of the foot Wrist In these areas, an artery passes close to the skin. To measure the pulse at the wrist, place the index and middle finge...
  15. Pulse - weak or absent Pulse - weak or absent
    A weak pulse means you have difficulty feeling a person's pulse (heartbeat). An absent pulse means you cannot detect a pulse at all. See also: CPR Considerations An absent or weak pulse may affect all or one part of the body. If a pulse cannot be detected by a non-medical professional, it doesn't ...
