    Similarly, examination may reveal wheezing and prolonged expiratory phase, or may be quite normal. Consequently, a potential for under-diagnosis exists. Measurement of airflow, such as peak expiratory flow rates, which can be done inexpensively on the track or sideline, may prove helpful.

  5. 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.

  6. 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. [2]

  7. Crackles - Wikipedia

    en.wikipedia.org/wiki/Crackles

    Crackles are more common during the inspiratory than the expiratory phase of breathing, but they may be heard during the expiratory phase. Crackles are often described as fine, medium, and coarse. They can also be characterized as to their timing: fine crackles are usually late-inspiratory, whereas coarse crackles are early inspiratory.

  8. 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.

    It presents with a hyperinflated chest, expiratory wheeze and low oxygen. [5] Severe pneumonia is most common in very young children age three to 18 months and presents with sudden illness, ongoing cough, high fever, shortness of breath and a fast rate of breathing. [5] There are frequently wheezes and crackles on breathing in and out. [5]
