When young people have chest tightness and shortness of breath, the measures needed to be taken depend on the causes of chest tightness and shortness of breath. In clinical practice, respiratory system diseases are common. Spontaneous pneumothorax or traumatic pneumothorax are caused by trauma or other reasons. At this time, it is necessary to lie in bed and rest in time. If necessary, the air in the pleural cavity is pumped out through closed thoracic drainage, so that the compressed normal lung tissue is reopened to form normal respiratory movement. In addition, it is also seen in hysteria caused by mental pressure, emotional excitement and other reasons, which leads to excessive ventilation and respiratory alkalosis. At this time, it is necessary to keep calm and give appropriate drugs to adjust the autonomic nervous function.
