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]
Atelectasis is the partial collapse or closure of a lung resulting in reduced or absent 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.
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 ...

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 ...
Tension pneumothorax is an emergent condition in which air gets trapped in the space between the chest wall and the lung. This space is referred to as the pleural space. Because air can't escape from this space, the air pocket grows larger and larger, resulting in the lung collapse closest to the pneumothorax.
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.
When the rib cage moves out, it no longer pulls the lungs with it. Thus the lungs cannot expand, the pressure in the lungs never drops and no air is pulled into the bronchi. Respiration is not possible. The affected lung, which has a great deal of elastic tissue, shrivels in what is referred to as a collapsed lung. [citation needed]
