Chest tightness can be relieved by lying down, which may be related to the improvement of blood supply, as well as the reduction of pressure in the pleural cavity and the relative smoothness of the respiratory tract, and is often seen in the cases of pneumothorax, bronchial tumor and heart disease.
1. Pneumothorax: after the occurrence of pneumothorax, the gas in the pleural cavity will enter into the chest cavity and affect the normal diastole of the chest cavity. After lying down, the gas in the pleural cavity may move, so that the pressure in the pleural cavity is relatively reduced and the symptom of chest tightness will be relieved to a certain extent.
2. Bronchial tumor: after the appearance of tumor in bronchial tube, it may press on the respiratory tract and cause local narrowing, when lying down, the local pressure may be reduced, and the symptoms of chest tightness will also be improved.
3. Heart disease: when heart disease patients lie down, due to the change of body position, there will be an increase in the performance of return blood volume, which can relieve myocardial ischemia to a certain extent and reduce chest tightness symptoms.
