Patients sitting with a sense of pressure on the chest, the common clinical reasons are mainly the following: First, patients due to lung malignant tumors or serious lung infection, often combined with a large amount of pleural effusion, when the bilateral lungs by the pleural fluid is severely compressed, the patient will have dyspnea and chest pressure, can improve the CT or ultrasound examination of the chest, strengthen the anti-infective treatment, leave a chest tube to drain the pleural fluid so as to reduce lung pressure, can gradually relieve the chest pressure, can gradually ease the pressure. The pressure on the chest can be gradually relieved. When the volume of anterior mediastinal tumor increases gradually, it will also cause chest compression. At this time, patients need to improve CT or magnetic resonance examination of mediastinum to make clear the specific location of the tumor, and then undergo surgery as soon as possible to remove the tumor. If necessary, postoperative chemotherapy and radiotherapy can be combined to avoid recurrence of tumor cells, so as to reduce the chest pressure symptoms.
