What is Which among the following is the most common organ affected in blast injury? and explain in detail?
A primary injury is caused by a direct effect of blast overpressure on tissue. Primary blast injury affects air-filled structures such as the lungs, ears, and GI tract the following mechanisms: spalling (e.g., from lung parenchyma to alveolar space, causing tissue surfaces to explode geyser-like); shearing, due to differential ineia (e.g., pulmonary vessels and air spaces), resulting in ruptured vascular and bronchial pedicles; and implosion of flexible air spaces, which rebound to greater than original size, resembling miniexplosions.
