D ICD – Biphasic positive airway pressure ventilation BiPAP is increasingly used as an alternative procedure to conventional assisted control ventilation for patients with acute respiratory distress syndrome and acute lung injury.
The important aspect for future involves studies to define in more detail the mechanistic importance of other cell types like alveolar epithelial cells and the alveolar macrophages. Other chest injuries, such as those of the great thoracic and esophageal vessels, are less frequent but are especially severe. Surg Clin North Am, 69pp.
Histopathological evaluation of the lung tissue at 8 min, 4 hr, and 12 hr post-contusion revealed diffuse intra-alveolar hemorrhage with alveolar disruption, along with interstitial hemorrhagic injury that frequently involve peri-hilar areas and extended contusoon the visceral surface conhusion the pleura.
Clinically, patients have hypoxiemia, hypercarbia and increase in labored breathing of varying severity and duration [ 7 ]. Pleural complications, such as hemothorax and pneumothorax, are also frequent. Blood in the alveolar spaces provide an excellent medium for bacteria.

R pulmonary contusion Chest wall injury. Ventilation can re-open collapsed alveoli, but their repeated opening will be harmful, and positive pressure ventilation can also damage the lung by overinflation [ 80 ].
Computed tomography CT pulmomar very sensitive for diagnosing pulmonary contusion. The excess fluid interferes with gas exchange leading to hypoxia. Peak abnormalities in deflation P-V mechanics occurred at 24 h post-contusion [ 35 ].
Clinically, patients with pulmonary contusion manifest in hypoxemia, hypercarbia, and intensified labored breathing [ 1 ].
