Injury at this level of the spinal cord might injure the phrenic nerve. This nerve supplies the diaphragm, which permits inspiration and expiration. If this nerve is damaged, the impulses no longer reach the diaphragm and the diaphragm stops contracting.
The diaphragm is the large circular end of the chest-piece. This side of device allows medical professionals to listen to a wider area of the patients body and picks up higher frequency sounds than the bell half of the chest-piece.
