The most common location of dry socket: in the socket of an extracted mandibular third molar (wisdom tooth). Since alveolar osteitis is not primarily an infection, there is not usually any pyrexia (fever) or cervical lymphadenitis (swollen glands in the neck), and only minimal edema (swelling) and erythema (redness) is present in the soft tissues surrounding the socket.
Overdistension of alveoli and cyclic atelectasis (atelectotrauma) are the primary causes for alveolar injury during positive pressure mechanical ventilation.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 ().
The membrane between alveoli and capillaries is torn; damage to this capillary–alveolar membrane and small blood vessels causes blood and fluids to leak into the alveoli and the interstitial space (the space surrounding cells) of the lung. [11] With more severe trauma, there is a greater amount of edema, bleeding, and tearing of the alveoli. [17]
Right side depicts what occurs after injury to the alveolus during the acute/exudative phase. Once the initial insult has damaged the alveoli and begun the process of DAD, the condition will typically progress in three phases: exudative, proliferative, and fibrotic. [6] Below are the description of the phases, paraphrased from Sweeney et al ...
Some patients rapidly recover from ALI and have no permanent sequelae. Prolonged inflammation and destruction of pneumocytes leads to fibroblastic proliferation, hyaline membrane formation, tracheal remodeling and lung fibrosis. This fibrosing alveolitis may become apparent as early as five days after the initial injury.
A physician will listen to the patient's lungs to help determine if there is likely a lower lung disease. Depending on the type of alveolar lung disease, the listener may hear "crackles" that indicate an excess of fluid in the lungs or an absence of lung sounds in certain regions which may indicate poor ventilation due to consolidation of pus ...

Whole lung lavage (WLL), also called lung washing, is a medical procedure in which the patient's lungs are washed with saline (salt water) by filling and draining repeatedly. It is used to treat pulmonary alveolar proteinosis , in which excess lung surfactant proteins prevent the patient from breathing.
