  2. Zones of the lung - Wikipedia

    On the other hand, gravity causes a gradient in blood pressure between the top and bottom of the lung of 20 mmHg in the erect position (roughly half of that in the supine position). Overall, mean pulmonary venous pressure is ~5 mmHg. Local venous pressure falls to -5 at the apexes and rises to +15 mmHg at the bases, again for the erect lung.

  3. Alveolar macrophage - Wikipedia

    en.wikipedia.org/wiki/Alveolar_macrophage

    Micrograph showing hemosiderin-laden alveolar macrophages, as seen in a pulmonary hemorrhage. H&E stain.. An alveolar macrophage, pulmonary macrophage, (or dust cell) is a type of macrophage, a professional phagocyte, found in the airways and at the level of the alveoli in the lungs, but separated from their walls.

  4. Interstitial lung disease - Wikipedia

    en.wikipedia.org/wiki/Interstitial_lung_disease

    Interstitial lung disease (ILD), or diffuse parenchymal lung disease (DPLD), [3] is a group of respiratory diseases affecting the interstitium (the tissue) and space around the alveoli (air sacs) of the lungs. [4] It concerns alveolar epithelium, pulmonary capillary endothelium, basement membrane, and perivascular and perilymphatic tissues. It ...

  5. Diffuse alveolar damage - Wikipedia

    en.wikipedia.org/wiki/Diffuse_alveolar_damage

    The most important factor for treating DAD or ARDS is to treat the underlying cause of the injury to the lungs, [9] for example pneumonia or sepsis. These patients will have problems with oxygenation, meaning they will likely need a breathing tube , medications to keep them comfortable (sedative, paralytic, and/or analgesic), and a mechanical ...

  6. Pulmonary alveolus - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_alveolus

    Insufficient surfactant in the lungs of preterm infants causes infant respiratory distress syndrome (IRDS). The lecithin–sphingomyelin ratio is a measure of fetal amniotic fluid to indicate lung maturity or immaturity. [28] A low ratio indicates a risk factor for IRDS. Lecithin and sphingomyelin are two of the glycolipids of pulmonary surfactant.

  7. Idiopathic interstitial pneumonia - Wikipedia

    en.wikipedia.org/wiki/Idiopathic_interstitial...

    Idiopathic interstitial pneumonia (IIP), or noninfectious pneumonia [1] are a class of diffuse lung diseases. These diseases typically affect the pulmonary interstitium, although some also have a component affecting the airways (for instance, cryptogenic organizing pneumonitis). There are seven recognized distinct subtypes of IIP. [2]

  8. Idiopathic pulmonary fibrosis - Wikipedia

    en.wikipedia.org/wiki/Idiopathic_pulmonary_fibrosis

    Idiopathic pulmonary fibrosis (IPF) synonymous with cryptogenic fibrosing alveolitis [5] is a rare, progressive illness of the respiratory system, characterized by the thickening and stiffening of lung tissue, associated with the formation of scar tissue.

  9. Dead space (physiology) - Wikipedia

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

    In healthy lungs where the alveolar dead space is small, Fowler's method accurately measures the anatomic dead space using a single breath nitrogen washout technique. [4] [5] The normal value for dead space volume (in mL) is approximately the lean mass of the body (in pounds), and averages about a third of the resting tidal volume (450-500 mL).
