When chest tightness and breath-holding occur in young people, the measures that need to be taken depend on the cause of the chest tightness and breath-holding. In clinical practice, it is more common to see respiratory diseases that cause spontaneous pneumothorax or traumatic pneumothorax due to trauma or other reasons. At this time, bed rest should be taken in a timely manner, and if necessary, the gas in the pleural cavity should be pumped out through closed chest drainage so that the compressed normal lung tissue can be reopened and normal respiratory movements can be formed. In addition, it is also seen that hysteria occurs due to mental stress and emotional excitement, which causes hyperventilation, resulting in respiratory alkalosis. At this time, it is necessary to stay calm, give appropriate drugs to adjust the plant nervous function, such as B-complex vitamins, glutamate, and if necessary, give valium to stabilize the emotion, and follow up with the doctor at any time to adjust the treatment plan.
