Yang Cheng, a Chinese doctor at Chongqing Mingbo Hospital, pointed out that COPD is a destructive lung disease characterized by incomplete reversible airflow restriction. Do more prevention work in life, not only can improve their resistance, but also can effectively cooperate with the doctor's treatment. Now let's introduce what are the complications of COPD?

What are the complications of COPD?

1. Spontaneous pneumothorax

Spontaneous pneumothorax complicated with obstructive emphysema is not uncommon. It is mostly caused by the rupture of the subpleural pulmonary bulla and the air leaking into the pleural cavity. If the basic pulmonary function of the patient is poor, and the pneumothorax is tensional, even if the volume of gas is small, the clinical manifestation is also heavy, and the patient must be actively rescued. The patients with emphysema have high transparency of the lung field, often have pulmonary bullae, and the signs are not typical enough, which brings some difficulties to the diagnosis of localized pneumothorax.

2. Respiratory failure

Obstructive emphysema often suffers from serious respiratory impairment. Under the influence of some inducements, such as respiratory tract infection, dry and retention of secretions, improper oxygen therapy, excessive use of intravenous agents, surgery, etc., the ventilation and ventilation dysfunction is further aggravated, which can lead to respiratory failure.

3. Chronic pulmonary heart disease and right heart failure

Hypoxemia, carbon dioxide retention and destruction of alveolar capillary bed can cause pulmonary hypertension. In the compensatory period of cardiac function, there was no right heart failure. When the disease of the respiratory system is further aggravated and the arterial blood gas worsens, the pulmonary artery pressure is significantly increased, the heart load is aggravated, and factors such as myocardial hypoxia and metabolic disorder can induce right heart failure.

4. Gastric ulcer

Autopsy confirmed that about 18%~30% of patients with obstructive emphysema had gastric ulcer. Its pathogenesis has not yet been completely clear.

5. Sleep disordered breathing

Normal people's ventilation can be slightly reduced during sleep, while obstructive emphysema patients' ventilation is significantly reduced during sleep. Especially when the patient is awake, the arterial partial pressure of oxygen has been as low as 8. When it is about 00kPa (60mmHg), it is more dangerous to further reduce during sleep. The sleep quality of patients decreases, which may lead to arrhythmia and pulmonary hypertension.

Yang Cheng, a famous old Chinese doctor in Chongqing

Graduated from Hunan University of Traditional Chinese Medicine, he has been engaged in clinical work of traditional Chinese medicine for nearly 30 years. During his clinical work in the No. 1 Affiliated Hospital of Hunan University of Traditional Chinese Medicine, he was impressed by the decline of traditional Chinese medicine and devoted himself to studying the theory and practice of traditional Chinese medicine. During this period, based on the systematic study of the classical literature of Chinese medicine, the clinical experience of previous generations of physicians and the scientific research achievements of modern medicine, we have made great achievements in the treatment of difficult diseases in Chinese medicine, which has been unanimously recognized by the Chinese medicine industry. Later, he learned from many famous old Chinese doctors in China, inherited and carried forward the quintessence of Chinese medicine, learned from the strengths of many families, and developed a school of its own in terms of efficacy, which won the praise and trust of patients.
