  2. Pneumothorax - Wikipedia

    en.wikipedia.org/wiki/Pneumothorax

    Very rarely, both lungs may be affected by a pneumothorax. [6] It is often called a "collapsed lung", although that term may also refer to atelectasis. [1] A primary spontaneous pneumothorax is one that occurs without an apparent cause and in the absence of significant lung disease. [3]

  3. Atelectasis - Wikipedia

    en.wikipedia.org/wiki/Atelectasis

    Atelectasis is the partial collapse or closure of a lung resulting in reduced or absence in gas exchange. It is usually unilateral, affecting part or all of one lung. [2] It is a condition where the alveoli are deflated down to little or no volume, as distinct from pulmonary consolidation, in which they are filled with liquid.

  4. Tracheal deviation - Wikipedia

    en.wikipedia.org/wiki/Tracheal_deviation

    Image shows early occurrence of tracheal deviation. Tracheal deviation is a clinical sign that results from unequal intrathoracic pressure within the chest cavity.It is most commonly associated with traumatic pneumothorax, but can be caused by a number of both acute and chronic health issues, such as pneumonectomy, atelectasis, pleural effusion, fibrothorax (pleural fibrosis), or some cancers ...

  5. Transpulmonary pressure - Wikipedia

    en.wikipedia.org/wiki/Transpulmonary_pressure

    If 'transpulmonary pressure' = 0 (alveolar pressure = intrapleural pressure), such as when the lungs are removed from the chest cavity or air enters the intrapleural space (a pneumothorax), the lungs collapse as a result of their inherent elastic recoil. Under physiological conditions the transpulmonary pressure is always positive; intrapleural ...

    Before my thoracic endometriosis diagnosis, one doctor said, “I’ve only ever read about this in my textbooks. I didn’t think people actually got this.”

  7. Intrapleural pressure - Wikipedia

    en.wikipedia.org/wiki/Intrapleural_pressure

    At rest, there is a negative intrapleural pressure. This provides a transpulmonary pressure, causing the lungs to expand. If humans didn't maintain a slightly negative pressure even when exhaling, their lungs would collapse on themselves because all the air would rush towards the area of lower pressure. Intra-pleural pressure is sub-atmospheric.

  8. Closing capacity - Wikipedia

    en.wikipedia.org/wiki/Closing_capacity

    As the lungs age, there is a gradual increase in the closing capacity (i.e. The small airways begin to collapse at a higher volume/before expiration is complete). This also occurs with certain disease processes, such as asthma , chronic obstructive pulmonary disease , and pulmonary edema .

  9. Tracheobronchial injury - Wikipedia

    en.wikipedia.org/wiki/Tracheobronchial_injury

    If the bronchiole is completely obstructed, atelectasis occurs: the alveoli of the lung collapse. [4] Lung tissue distal to a completely obstructed bronchiole often does not become infected. Because it is filled with mucus, this tissue remains functional. [22] When the secretions are removed, the affected portion of the lung is commonly able to ...
