  2. Minute ventilation - Wikipedia

    en.wikipedia.org/wiki/Minute_ventilation

    Minute ventilation (or respiratory minute volume or minute volume) is the volume of gas inhaled (inhaled minute volume) or exhaled (exhaled minute volume) from a person's lungs per minute. It is an important parameter in respiratory medicine due to its relationship with blood carbon dioxide levels .

  3. Control of ventilation - Wikipedia

    en.wikipedia.org/wiki/Control_of_ventilation

    The control of ventilation is the physiological mechanisms involved in the control of breathing, which is the movement of air into and out of the lungs. Ventilation facilitates respiration. Respiration refers to the utilization of oxygen and balancing of carbon dioxide by the body as a whole, or by individual cells in cellular respiration. [1]

  4. Respiratory system - Wikipedia

    en.wikipedia.org/wiki/Respiratory_system

    This information determines the average rate of ventilation of the alveoli of the lungs, to keep these pressures constant. The respiratory center does so via motor nerves which activate the diaphragm and other muscles of respiration. The breathing rate increases when the partial pressure of carbon dioxide in the blood increases.

  5. Pulmonary gas pressures - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_gas_pressures

    The alveolar oxygen partial pressure is lower than the atmospheric O 2 partial pressure for two reasons. Firstly, as the air enters the lungs, it is humidified by the upper airway and thus the partial pressure of water vapour (47 mmHg) reduces the oxygen partial pressure to about 150 mmHg.

  6. Lung volumes and capacities - Wikipedia

    en.wikipedia.org/wiki/Lung_volumes_and_capacities

    Lung volumes and lung capacities are measures of the volume of air in the lungs at different phases of the respiratory cycle. The average total lung capacity of an adult human male is about 6 litres of air. [1] Tidal breathing is normal, resting breathing; the tidal volume is the volume of air that is inhaled or exhaled in only a single such ...

  7. Spirometry - Wikipedia

    en.wikipedia.org/wiki/Spirometry

    Total lung capacity: the volume in the lungs at maximal inflation, the sum of VC and RV. TV: Tidal volume: that volume of air moved into or out of the lungs in 1 breath (TV indicates a subdivision of the lung; when tidal volume is precisely measured, as in gas exchange calculation, the symbol TV or V T is used.) RV

  8. Ventilation/perfusion ratio - Wikipedia

    en.wikipedia.org/wiki/Ventilation/perfusion_ratio

    Therefore, under these conditions, the ideal ventilation perfusion ratio would be about 0.95. If one were to consider humidified air (with less oxygen), then the ideal v/q ratio would be in the vicinity of 1.0, thus leading to concept of ventilation-perfusion equality or ventilation-perfusion matching. This matching may be assessed in the lung ...

  9. Pulmonary alveolus - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_alveolus

    A pulmonary alveolus (pl. alveoli; from Latin alveolus 'little cavity'), also called an air sac or air space, is one of millions of hollow, distensible cup-shaped cavities in the lungs where pulmonary gas exchange takes place. [1] Oxygen is exchanged for carbon dioxide at the blood–air barrier between the alveolar air and the pulmonary ...
