Of people with pulmonary contusion alone, 17% develop ARDS, while 78% of people with at least two additional injuries develop the condition. [6] A larger contusion is associated with an increased risk. In one study, 82% of people with 20% or more of the lung volume affected developed ARDS, while only 22% of people with less than 20% did so. [7]
2 ratio indicates reduced arterial oxygenation from the available inhaled gas): mild ARDS: 201 – 300 mmHg (≤ 39.9 kPa) moderate ARDS: 101 – 200 mmHg (≤ 26.6 kPa) severe ARDS: ≤ 100 mmHg (≤ 13.3 kPa) The Berlin definition requires a minimum positive end expiratory pressure (PEEP) of 5 cm H 2 O for consideration of the Pa O 2 /Fi O 2 ...
VALI is most common in people receiving mechanical ventilation for acute lung injury or acute respiratory distress syndrome (ALI/ARDS). [1] 24 percent of people mechanically ventilated will develop VALI for reasons other than ALI or ARDS. [1] The incidence is probably higher among people who already have ALI/ARDS, but estimates vary widely. [1]
The pathophysiology of acute respiratory distress syndrome involves fluid accumulation in the lungs not explained by heart failure (noncardiogenic pulmonary edema). It is typically provoked by an acute injury to the lungs that results in flooding of the lungs' microscopic air sacs responsible for the exchange of gases such as oxygen and carbon dioxide with capillaries in the lungs.

Benign conditions potentially leading to the formation of nodular GGOs include aspergillosis, acute eosinophilic pneumonia, focal interstitial fibrosis, granulomatosis with polyangiitis, IgA vasculitis, organizing pneumonia, pulmonary contusion, pulmonary cryptococcus, and thoracic endometriosis. Focal interstitial fibrosis presents a unique ...
U.S. farm industry groups want President-elect Donald Trump to spare their sector from his promise of mass deportations, which could upend a food supply chain heavily dependent on immigrants in ...
Flail chest is usually accompanied by a pulmonary contusion, a bruise of the lung tissue that can interfere with blood oxygenation. [5] Often, it is the contusion, not the flail segment, that is the main cause of respiratory problems in people with both injuries. [6] Surgery to fix the fractures appears to result in better outcomes. [7]
Former U.S. Rep. Adam Kinzinger is reflecting on a pivotal moment that helped shaped his life and career. In the new documentary The Last Republican — which opened at New York City's Film Forum ...
