2. Wheeze - Wikipedia

   en.wikipedia.org/wiki/Wheeze

   A wheeze is a clinical symptom of a continuous, coarse, whistling sound produced in the respiratory airways during breathing. [1] For wheezes to occur, part of the respiratory tree must be narrowed or obstructed (for example narrowing of the lower respiratory tract in an asthmatic attack), or airflow velocity within the respiratory tree must be heightened.

3. Respiratory sounds - Wikipedia

   en.wikipedia.org/wiki/Respiratory_sounds

   Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds.

4. Obstructive lung disease - Wikipedia

   en.wikipedia.org/wiki/Obstructive_lung_disease

   COPD is defined as a forced expiratory volume in 1 second divided by the forced vital capacity (FEV1/FVC) that is less than 0.7 (or 70%). [8] The residual volume, the volume of air left in the lungs following full expiration, is often increased in COPD, as is the total lung capacity, while the vital capacity remains relatively normal.

5. Pulmonary function testing - Wikipedia

   en.wikipedia.org/wiki/Pulmonary_function_testing

   Measurement of maximal inspiratory and expiratory pressures is indicated whenever there is an unexplained decrease in vital capacity or respiratory muscle weakness is suspected clinically. Maximal inspiratory pressure (MIP) is the maximal pressure that can be produced by the patient trying to inhale through a blocked mouthpiece.

   Certain breathing strategies help people with COPD enjoy physical activity. These strategies, primarily pursed-lip breathing and diaphragmatic breathing, move air through their lungs more efficiently.

7. 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 ...
