  2. Intrapleural pressure - Wikipedia

    en.wikipedia.org/wiki/Intrapleural_pressure

    Normally, the pressure within the pleural cavity is slightly less than the atmospheric pressure, which is known as negative pressure. [1] When the pleural cavity is damaged or ruptured and the intrapleural pressure becomes greater than the atmospheric pressure, pneumothorax may ensue. Intrapleural pressure is different from intrathoracic pressure.

  3. Transpulmonary pressure - Wikipedia

    en.wikipedia.org/wiki/Transpulmonary_pressure

    The alveolar pressure is estimated by measuring the pressure in the airways while holding one's breath. [2] The intrapleural pressure is estimated by measuring the pressure inside a balloon placed in the esophagus. [2] Measurement of transpulmonary pressure assists in spirometry in availing for calculation of static lung compliance.

  4. Zones of the lung - Wikipedia

    en.wikipedia.org/wiki/Zones_of_the_lung

    Local venous pressure falls to -5 at the apexes and rises to +15 mmHg at the bases, again for the erect lung. Pulmonary blood pressure is typically in the range 25–10 mmHg with a mean pressure of 15 mmHg. Regional arterial blood pressure is typically in the range 5 mmHg near the apex of the lung to 25 mmHg at the base.

  5. Alveolar pressure - Wikipedia

    en.wikipedia.org/wiki/Alveolar_pressure

    Image illustrating transpulmonary, intrapleural and intra-alveolar pressure. Alveolar pressure (P alv) is the pressure of air inside the lung alveoli. When the glottis is opened and no air is flowing into or out of the lungs, alveolar pressure is equal to the atmospheric pressure, that is, zero cmH 2 O. [1] [2]

  6. Pulmonary gas pressures - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_gas_pressures

    The partial pressure of carbon dioxide, along with the pH, can be used to differentiate between metabolic acidosis, metabolic alkalosis, respiratory acidosis, and respiratory alkalosis. Hypoventilation exists when the ratio of carbon dioxide production to alveolar ventilation increases above normal values – greater than 45mmHg.

  9. Respiration (physiology) - Wikipedia

    en.wikipedia.org/wiki/Respiration_(physiology)

    The process of breathing does not fill the alveoli with atmospheric air during each inhalation (about 350 ml per breath), but the inhaled air is carefully diluted and thoroughly mixed with a large volume of gas (about 2.5 liters in adult humans) known as the functional residual capacity which remains in the lungs after each exhalation, and ...
