This can cause a steadily worsening oxygen shortage and low blood pressure. This leads to a type of shock called obstructive shock, which can be fatal unless reversed. [3] 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]
Severe injury to alveoli causes swelling of the tissues (edema) in the lungs, bleeding of the alveoli, loss of surfactant (decrease in lung compliance) and complete alveoli collapse . [ 1 ] [ 8 ] High flow rates are associated with rheotrauma , high volumes with volutrauma and pressures with barotrauma .
Macri's lungs were filled with dust when the towers collapsed and he later spent two months working on the site. The long hours on the site gave him vomiting spells and he was diagnosed with an already rapidly progressing stage four cancer only one year after the attack, despite being a non-smoker and cancer free before the attacks.

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.
Inflammation of the lungs, which can result when components of blood enter the tissue due to contusion, can also cause parts of the lung to collapse. Macrophages , neutrophils , and other inflammatory cells and blood components can enter the lung tissue and release factors that lead to inflammation, increasing the likelihood of respiratory ...
Chest tube clogging can lead to retained blood around the heart and lungs that can contribute to complications and increase mortality. [11] A common complication after thoracic surgery that arises within 30–50% of patients are air leaks. If a chest tube clogs when there is an air leak the patient will develop a pneumothorax.
Bridges have collapsed from collisions with ships before. Between 1960 and 2015, there were 35 major bridge collapses that happened after they were hit by a marine vessel, said Toby Mottram from ...
The septa are lined with atypical, hyperplastic type II pneumocytes, thus leading to the collapse of airspaces. Other diagnostic tests are useful in excluding other similar conditions, but history, X-ray, and biopsy are essential. These other tests may include basic blood work, blood cultures, and bronchoalveolar lavage. [citation needed]
