Document Summary
These injuries can be life threatening resulting in hypoxemia, hypovolemia, and cardiac failure resulting in impaired perfusion and ventilation acute kidney injury, hypovolemic shock, and death. Blunt (more common: causes: mva (seatbelt, steering wheel, falls, bike crashes-handlebars, types: rib/ sternal fractures, flail chest, pulmonary contusion, flail chest: multiple ribs broken in 2 places. Fractured area will sink in when breathing in and come out when breathing out. Movement: pulmonary contusion: bruising internally on soft tissue of lung resulting in hemorrhage and localized edema. Can drain it: subcutaneous emphysema: air leaks out of pleural cavity and goes to the tissue, under the skin. Can happen from chest tube but not a serious complication, and can fix resolve on its own: pneumothorax: pleural space exposed to positive pressure and the lung collapses. Chest tube needed. (diminished or absent breath sounds). Dyspnea, tachypnea, chest pain, tracheal deviation toward affected side, hypoxemia (if large): simple/spontaneous pneumothorax: air enters pleural space through rupture of bleb/blister.
