  3. Acute exacerbation of chronic obstructive pulmonary disease

    en.wikipedia.org/wiki/Acute_exacerbation_of...

    The definition of a COPD exacerbation is commonly described as "lost in translation", [9] meaning that there is no universally accepted standard with regard to defining an acute exacerbation of COPD. Many organizations consider it a priority to create such a standard, as it would be a major step forward in the diagnosis and quality of treatment ...

    en.wikipedia.org/wiki/Chronic_obstructive...

    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 ...

  5. Asthma-COPD overlap - Wikipedia

    en.wikipedia.org/wiki/Asthma-COPD_overlap

    ACO presents with symptoms of both asthma and COPD. [1] ACO presents in adulthood, usually after the age of 40 (after there has been significant tobacco smoke or other toxic fumes exposure), with symptoms of dyspnea (shortness of breath), exercise intolerance, sputum production, cough and episodes of symptomatic worsening known as exacerbations.

  6. Obstructive lung disease - Wikipedia

    en.wikipedia.org/wiki/Obstructive_lung_disease

    The most common cause of COPD is cigarette smoking. COPD is a gradually progressive condition and usually only develops after about 20 pack-years of smoking. COPD may also be caused by breathing in other particles and gases. [citation needed] The diagnosis of COPD is established through spirometry although other pulmonary function tests can be ...

  7. Emphysema - Wikipedia

    en.wikipedia.org/wiki/Emphysema

    When associated with significant airflow limitation, emphysema is a major subtype of chronic obstructive pulmonary disease (COPD), a progressive lung disease characterized by long-term breathing problems and poor airflow. [10] [11] Without COPD, the finding of emphysema on a CT lung scan still confers a higher mortality risk in tobacco smokers ...

    In 1994, a new definition was recommended by the American-European Consensus Conference Committee [6] [10] which recognized the variability in severity of pulmonary injury. [51] The definition required the following criteria to be met: acute onset, persistent dyspnea; bilateral infiltrates on chest radiograph consistent with pulmonary edema

  9. Respiratory failure - Wikipedia

    en.wikipedia.org/wiki/Respiratory_failure

    Increased airways resistance (chronic obstructive pulmonary disease, asthma, suffocation) Reduced breathing effort (drug effects, brain stem lesion, extreme obesity) A decrease in the area of the lung available for gas exchange (such as in chronic bronchitis) Neuromuscular problems (Guillain–Barré syndrome, [2] motor neuron disease)
