Spinal cord injuries are devastating events. In the U.S., most are the result of automobile collisions, but falls, penetrating injuries, and blunt trauma can also cause injury to the spinal cord, leading to a respiratory emergency. It is estimated that there are more than 18,000 spinal cord injuries each year in the U.S. When the injuries involve the cervical vertebrae, specifically the midsection (C3 through C5), they can disrupt the phrenic nerve, which controls the movement of the diaphragm, rendering the patient unable to breathe on their own.
