Caustic agent inhalation injuries are assigned to which ISS body region?

Inhalation injuries caused by caustic agents primarily affect the respiratory system, which is part of the chest region. When caustic substances are inhaled, they can cause significant damage to the airway and lung tissues, leading to complications such as chemical burns, inflammation, and respiratory distress. The chest region encompasses not only the lungs but also the trachea, bronchi, and the entirety of the thoracic cavity where these injuries manifest.

In contrast, injuries classified under other body regions, such as the abdomen, head/neck, or extremities, do not pertain to the inhalation of caustic agents. For instance, abdominal injuries would involve trauma or burns to the digestive organs, while head/neck injuries would involve the skull, brain, or cervical structures. Extremities refer to damage to limbs, which is unrelated to inhalation-related injuries. This is why the appropriate assignment for caustic agent inhalation injuries is the chest region.
