Phrenic nerve injuries can be caused by blunt trauma to the neck, which can damage the nerve directly. Brainstem strokes can affect the neural pathways that control diaphragm movement, indirectly leading to phrenic nerve dysfunction. Spinal cord tumors can also impinge on the nerve roots that contribute to the phrenic nerve, leading to its injury. Apneustic breathing is a pattern of breathing, not a cause of phrenic nerve injury.
