Numbness

Diaphragmatic paralysis is caused by the damage to the phrenic nerve and the impulse of the nerve. The paralysis of one or both sides of the phrenic muscle rises and the movement is disturbed. Long-term diaphragmatic paralysis can cause diaphragmatic atrophy to form a thin film. One side diaphragm palsy can reduce the vital capacity by 37% and the ventilation volume by 20%. However, due to the compensatory effect, patients are usually asymptomatic and have shortness of breath only in the supine position. The left paralysis palsy may have gastrointestinal symptoms such as belching, abdominal distension, and abdominal pain due to an elevated gastric fundus. The bilateral diaphragmatic palsy showed cyanosis, marked dyspnea, sitting breathing, and hypoxemia.
