  2. Diaphragmatic breathing - Wikipedia

    en.wikipedia.org/wiki/Diaphragmatic_breathing

    Air enters the lungs as the diaphragm strongly contracts, but unlike during traditional relaxed breathing the intercostal muscles of the chest do minimal work in this process. The belly also expands during this type of breathing to make room for the contraction of the diaphragm. [3]

  3. Shallow breathing - Wikipedia

    en.wikipedia.org/wiki/Shallow_breathing

    Shallow breathing, thoracic breathing, costal breathing or chest breathing [1] is the drawing of minimal breath into the lungs, usually by drawing air into the chest area using the intercostal muscles rather than throughout the lungs via the diaphragm. Shallow breathing can result in or be symptomatic of rapid breathing and hypoventilation ...

  4. Muscles of respiration - Wikipedia

    en.wikipedia.org/wiki/Muscles_of_respiration

    The diaphragm is the major muscle responsible for breathing.It is a thin, dome-shaped muscle that separates the abdominal cavity from the thoracic cavity. During inhalation, the diaphragm contracts, so that its center moves caudally (downward) and its edges move cranially (upward).

  5. Respiratory examination - Wikipedia

    en.wikipedia.org/wiki/Respiratory_examination

    Diaphragmatic breathing, paradoxical movement of the diaphragm outwards during inspiration; Intercostal indrawing; Decreased chestchest movement on the affected side; An increased jugular venous pressure, indicating possible right heart failure [5] The anterior and posterior chest wall are also inspected for any abnormalities, which may include:

  6. Diaphragmatic excursion - Wikipedia

    en.wikipedia.org/wiki/Diaphragmatic_excursion

    Diaphragmatic excursion is the movement of the thoracic diaphragm during breathing. Normal diaphragmatic excursion should be 3–5 cm, but can be increased in well-conditioned persons to 7–8 cm. This measures the contraction of the diaphragm. It is performed by asking the patient to exhale and hold it.

  7. Complete breathing - Wikipedia

    en.wikipedia.org/wiki/Complete_breathing

    Clavicular breathing is the final stage of the overall chest expansion. It happens after the chest inhalation is complete. To get more air into the lungs, the upper ribs and collarbones are pulled upward by the neck, larynx and sternum muscles. This requires maximum chest expansion during inhalation, and only the upper lobe of the lung is ...

  8. Breathing - Wikipedia

    en.wikipedia.org/wiki/Breathing

    The lungs are not capable of inflating themselves, and will expand only when there is an increase in the volume of the thoracic cavity. [6] [7] In humans, as in the other mammals, this is achieved primarily through the contraction of the diaphragm, but also by the contraction of the intercostal muscles which pull the rib cage upwards and outwards as shown in the diagrams on the right. [8]

  9. Work of breathing - Wikipedia

    en.wikipedia.org/wiki/Work_of_breathing

    The normal relaxed state of the lung and chest is partially empty. Further exhalation requires muscular work. Inhalation is an active process requiring work. [4] Some of this work is to overcome frictional resistance to flow, and part is used to deform elastic tissues, and is stored as potential energy, which is recovered during the passive process of exhalation, Tidal breathing is breathing ...
