summary

What is contradictory movement of chest and abdomen? Thoracoabdominal contradictory movement refers to the contradictory state of thoracoabdominal movement in patients with emphysema, that is, the chest movement outward and the abdominal wall movement inward when inhaled. So, what is the reason for the contradictory movement of chest and abdomen? Let's introduce it to you.

What is contradictory movement of chest and abdomen?

The pathogenesis of obstructive pulmonary emphysema is still unclear. It is generally considered to be related to bronchial obstruction and protease Antiproteinase imbalance. Smoking, infection and air pollution cause bronchiolitis, narrow or blocked lumen. When inhaled, the bronchioles dilated and the air entered the alveoli; During exhalation, the lumen shrinks, the air is trapped, and the pressure in alveoli increases continuously, which leads to the excessive expansion and even rupture of alveoli.

The radial traction loss around the bronchioles causes the bronchioles to contract and narrow the lumen. The thickening of pulmonary vascular intima, the decrease of blood supply of alveolar wall and the weakening of alveolar elasticity contribute to the rupture of inflated alveoli. In the case of infection, the activity of protease in the body increases, and the activity of anti protease system in normal people increases accordingly, so as to protect the lung tissue from damage. α The deficiency of antitrypsin can weaken the inhibition of protease, so emphysema is more likely to occur. Smoking also has adverse effects on protease Antiproteinase balance.

The clinical manifestations were mild and the degree of emphysema was important. Early symptomless or only in labor, exercise feel shortness of breath, gradually unable to do the original work. With the development of emphysema, the degree of dyspnea increases, and even shortness of breath is felt when a little activity or even complete rest. In addition, you can also feel fatigue, weight loss, loss of appetite, upper abdominal fullness. The main cause of emphysema is chronic bronchitis, so in addition to shortness of breath, there are cough, expectoration and other symptoms, early only prolonged expiratory phase or no abnormal.

matters needing attention

We have plenty of protein and iron. Diet should eat lean meat, animal liver, tofu, soybean milk, etc. These foods are not only rich in high-quality protein and iron, but also have no disadvantages of increasing phlegm and heat. They are good for strengthening patients' physique, improving disease resistance and promoting the repair of damaged tissues. Eat more foods containing vitamin A, C and calcium. Food containing vitamin A, such as pig liver, egg yolk, cod liver oil, carrot, pumpkin, apricot, etc; It has the effect of moistening the lung and protecting the trachea. Foods containing vitamin C have anti-inflammatory, anti-cancer and anti cold functions, such as jujube, pomelo, tomato, green pepper, etc; Calcium containing foods can enhance the antiallergic ability of trachea, such as pig bone, green vegetables, tofu, sesame paste, etc. It should be noted that dairy products can thicken the sputum and make it difficult to discharge, thus aggravating the infection. Therefore, it is necessary to limit the intake of milk and its products.
