  2. Subcutaneous emphysema - Wikipedia

    Small cuts, or "blow holes", may be made in the skin to release the gas. [16] When subcutaneous emphysema occurs due to pneumothorax, a chest tube is frequently used to control the latter; this eliminates the source of the air entering the subcutaneous space. [2]

    They also equalize the pressure in adjacent alveoli and, combined with increased distribution of surfactant, thus play an important role in prevention of collapse of the lung. [ 6 ] Unlike adults, in children these inter-alveolar connections are poorly developed which aids in limiting the spread of infection.

  4. Emphysema - Wikipedia

    en.wikipedia.org/wiki/Emphysema

    Centrilobular emphysema, also called centriacinar emphysema, affects the centre of a pulmonary lobule (centrilobular) in the lung, the area around the terminal bronchiole and the first respiratory bronchiole, and can be seen on imaging as an area around the tip of the visible pulmonary artery. Centrilobular emphysema is the most common type ...

    en.wikipedia.org/wiki/Collateral_ventilation

    A study showed that those with emphysema had a ten-fold increase of collateral ventilation over healthy controls. [9] The intent of lung volume reduction is to achieve the complete collapse (atelectasis) of an entire lobe of the lung in order to reduce volume in the chest, restore elastic recoil and improve breathing. Interlobar collateral ...

    Further changes in blood flow can lead to decline in lung function. Emphysema is another disease of the lungs, whereby the elastin in the walls of the alveoli is broken down by an imbalance between the production of neutrophil elastase (elevated by cigarette smoke) and alpha-1 antitrypsin (the activity varies due to genetics or reaction of a ...

    Emphysema is a chronic lung condition that causes shortness of breath. The disease is generally caused by cigarette smoking (the 78-year-old Lynch is a lifelong smoker) or exposure to pollutants.

  8. Respiratory disease - Wikipedia

    en.wikipedia.org/wiki/Respiratory_disease

    Respiratory diseases, or lung diseases, [1] are pathological conditions affecting the organs and tissues that make gas exchange difficult in air-breathing animals. They include conditions of the respiratory tract including the trachea, bronchi, bronchioles, alveoli, pleurae, pleural cavity, the nerves and muscles of respiration.
