Pulmonary dysfunction


If the C4 nerve in the brachial plexus nerve network is injured, there may be diaphragm paralysis or weakness. This issue may go undiagnosed because it may be hidden within the child's behavior. The child may seem extra tired, may not have a lot of strength or endurance and may lose function often. A physician may not "hear" any problems in the lungs, but if a pulmonary function test is administered, a reduction in pulmonary function is seen.
