In this case, if the collapse of the thorax caused by rib fractures will generally cause inflammation, contusion of the lung tissue, pneumothorax, hemothorax and other complications, leading to difficulty breathing, which may be life-threatening in severe cases. If there is no massive pneumothorax or hemothorax, there is no danger if there is no dyspnea. First, the chest should be fixed, and the collapsed ribs should be suspended to relieve the compression of the lung tissue. Only by stabilizing the respiratory function can the patient gradually improve. If the collapse is severe, the ribs should be surgically fixed after stabilization.
