  2. Pneumothorax - Wikipedia

    en.wikipedia.org/wiki/Pneumothorax

    Spontaneous pneumothorax is, as in humans, classified as primary or secondary, while traumatic pneumothorax is divided into open and closed (with or without chest wall damage). [63] The diagnosis may be apparent to the veterinary physician because the animal exhibits difficulty breathing in, or has shallow breathing.

  3. 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 ...

  4. Pulmonary laceration - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_laceration

    Therefore, pneumothorax is usually more of a problem than hemothorax. [8] A pneumothorax may form or be turned into a tension pneumothorax by mechanical ventilation, which may force air out of the tear in the lung. [12] The laceration may also close up by itself, which can cause it to trap blood and potentially form a cyst or hematoma. [8]

  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 ...

  6. Subcutaneous emphysema - Wikipedia

    en.wikipedia.org/wiki/Subcutaneous_emphysema

    Subcutaneous emphysema can be caused by medical procedures and medical conditions that cause the pressure in the alveoli of the lung to be higher than that in the tissues outside of them. [4] Its most common causes are pneumothorax or a chest tube that has become occluded by a blood clot or fibrinous material.

  7. Intrapleural pressure - Wikipedia

    en.wikipedia.org/wiki/Intrapleural_pressure

    Pneumothorax Condition; A person breathing at rest inhales and exhales approximately half a liter of air during each respiratory cycle, which is called tidal volume. The respiratory rate is directly affected by the concentration of carbon dioxide in the blood. Lungs do not collapse after forceful respiration because of the residual volume.

  8. Tracheobronchial injury - Wikipedia

    en.wikipedia.org/wiki/Tracheobronchial_injury

    Injuries to the tracheobronchial tree within the chest may occur due to penetrating forces such as gunshot wounds, but are more often the result of blunt trauma. [6] TBI due blunt forces usually results from high-energy impacts such as falls from height and motor vehicle accidents; the injury is rare in low-impact mechanisms. [2]

  9. Thorax - Wikipedia

    en.wikipedia.org/wiki/Thorax

    Pneumothorax is the condition where air or gas can build up in the pleural space. It can occur without a known cause or as the result of a lung disease or acute lung injury. [10] The size of the pneumothorax changes as air or gas builds up, so a medical procedure can release the pressure with a needle.
