Collection of air in the subcutaneous layers
Either bruise to lung; or bruise to heart; AMI like chest pain, arrhythmias and disturbances

The correct answer is: Collection of air in the subcutaneous layers

The correct answer identifies the condition known as subcutaneous emphysema, which is characterized by the accumulation of air in the subcutaneous tissue—the layers of skin beneath the surface. This phenomenon often occurs after trauma, such as a punctured lung or a severe chest injury, allowing air to migrate from the lungs or chest cavity into the soft tissues of the body. Understanding this condition is vital for EMTs because it may signal an underlying injury that requires immediate attention. Recognition of subcutaneous emphysema can help guide the appropriate interventions, such as monitoring for respiratory distress or other complications that may arise from thoracic injuries.
