  2. Pulmonary angiography - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_angiography

    Selective pulmonary angiogram revealing significant thrombus (labelled A) causing a central obstruction in the left main pulmonary artery. Pulmonary angiography (or pulmonary arteriography,conventional pulmonary angiography, selective pulmonary angiography) is a medical fluoroscopic procedure used to visualize the pulmonary arteries and much less frequently, the pulmonary veins.

  3. Computed tomography angiography - Wikipedia

    en.wikipedia.org/wiki/Computed_tomography...

    CT pulmonary angiogram (CTPA) is used to examine the pulmonary arteries in the lungs, most commonly to rule out pulmonary embolism (PE), a serious but treatable condition. It has become the technique of choice for detection of pulmonary embolism due to its wide availability, short exam time, ability to see other diseases that may present like ...

    en.wikipedia.org/wiki/CT_pulmonary_angiogram

    CTPA was introduced in the 1990s as an alternative to ventilation/perfusion scanning (V/Q scan), which relies on radionuclide imaging of the blood vessels of the lung. It is regarded as a highly sensitive and specific test for pulmonary embolism. [1] CTPA is typically only requested if pulmonary embolism is suspected clinically.

    Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by chronic respiratory symptoms and airflow limitation. [8] GOLD 2024 defined COPD as a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea or shortness of breath, cough, sputum production or exacerbations) due to abnormalities of the airways (bronchitis ...

  6. BODE index - Wikipedia

    en.wikipedia.org/wiki/BODE_Index

    The BODE index, for Body-mass index, airflow Obstruction, Dyspnea, and Exercise, is a multidimensional scoring system and capacity index used to test patients who have been diagnosed with chronic obstructive pulmonary disease (COPD) and to predict long-term outcomes for them. The index uses the four factors to predict risk of death from the ...

  7. Obstructive shock - Wikipedia

    en.wikipedia.org/wiki/Obstructive_shock

    Risk factors are conditions that increase the risk of clotting. This includes genetic (factor V Leiden) and acquired conditions (cancer). [17] Trauma, surgery, and prolonged bed-rest are common risks. Covid-19 is a recent risk factor. [18] This obstruction increases the pulmonary vascular resistance. If large enough, the clot increases the load ...
