  2. Chronic obstructive pulmonary disease - Wikipedia

    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 ...

  3. Pulmonary function testing - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_function_testing

    Pulmonary function testing (PFT) is a complete evaluation of the respiratory system including patient history, physical examinations, and tests of pulmonary function. The primary purpose of pulmonary function testing is to identify the severity of pulmonary impairment. [ 1 ]

  4. Spirometry - Wikipedia

    en.wikipedia.org/wiki/Spirometry

    Spirometry (meaning the measuring of breath) is the most common of the pulmonary function tests (PFTs). It measures lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled.

  5. FEV1/FVC ratio - Wikipedia

    en.wikipedia.org/wiki/FEV1/FVC_ratio

    In obstructive lung disease, the FEV1 is reduced due to an obstruction of air escaping from the lungs. Thus, the FEV1/FVC ratio will be reduced. [4] More specifically, according to the National Institute for Clinical Excellence, the diagnosis of COPD is made when the FEV 1 /FVC ratio is less than 0.7 or [8] the FEV 1 is less than 75% of predicted; [9] however, other authoritative bodies have ...

  6. Vital capacity - Wikipedia

    en.wikipedia.org/wiki/Vital_capacity

    A normal adult has a vital capacity between 3 and 5 litres. [3] A human's vital capacity depends on age, sex, height, mass, and possibly ethnicity. [ 4 ] However, the dependence on ethnicity is poorly understood or defined, as it was first established by studying black slaves in the 19th century [ 5 ] and may be the result of conflation with ...

  7. Peak expiratory flow - Wikipedia

    en.wikipedia.org/wiki/Peak_expiratory_flow

    The highest of three readings is used as the recorded value of the Peak Expiratory Flow Rate. It may be plotted out on graph paper charts together with a record of symptoms or using peak flow charting software. This allows patients to self-monitor and pass information back to their doctor or nurse.

  8. Ventilation/perfusion ratio - Wikipedia

    en.wikipedia.org/wiki/Ventilation/perfusion_ratio

    Ideally, the oxygen provided via ventilation would be just enough to saturate the blood fully. In the typical adult, 1 litre of blood can hold about 200 mL of oxygen; 1 litre of dry air has about 210 mL of oxygen. Therefore, under these conditions, the ideal ventilation perfusion ratio would be about 0.95.

  9. Spirometer - Wikipedia

    en.wikipedia.org/wiki/Spirometer

    A spirometer is the main piece of equipment used for basic Pulmonary Function Tests (PFTs). Lung diseases such as asthma, bronchitis, and emphysema may be ruled out from the tests. In addition, a spirometer often is used for finding the cause of shortness of breath, assessing the effect of contaminants on lung function, the effect of medication ...
