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 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.
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 ...
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.”
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 .
The pathophysiology of type 3 respiratory failure often includes lung atelectasis, which is a term used to describe a collapsing of the functional units of the lung that allow for gas exchange. Because atelectasis occurs so commonly in the perioperative period, this form is also called perioperative respiratory failure.
Chest x-ray demonstrating severe atelectasis or collapse of the right lung and mediastinal shift towards the right. Atelectasis is the partial collapse of a lung that is reversible. There are numerous etiologies, including post-operative atelectasis, surfactant deficiency, mucus plugging, and foreign body aspiration.
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 ...
