Explain cor pulmona, the description of pulmonary dyspnea is incorrect .

Cormonale dyspnea is a condition in which patients feel that they have insufficient air, strained breathing, and are accompanied by abnormal respiratory rate, depth, and rhythm due to respiratory diseases. In severe cases, nasal flaring, mouth opening, or orthopnea may occur. There are three types of inspiratory dyspnea, characterized by significant difficulty in inspiration.

In severe cases, the supracnal fossa, supraclavicular fossa, and intercostal space are markedly depressed during inspiration. It is accompanied by a dry cough and high-pitched inspiratory wheezing. It occurs in connection with narrowing of the large airways and obstruction.

Expiratory dyspnea is characterized by markedly labored expiration, prolonged expiratory time, and widespread wheezing. It is caused by weakened elasticity of lung tissue and spasm and stenosis of small bronchosm, such as emphysema, bronchial asthma, etc. Mixed dyspnea is characterized by a labored inhalation and exhalation, and shallow and rapid breathing.

It is caused by a reduction in the respiratory area due to extensive lung lesions, such as severe pneumonia, tuberculosis, massive pleural effusion, pneumothorax, etc. Common diseases include asthma, bronchiectasis, chronic obstructive pulmonary disease (COPD; Pneumonia, tuberculosis, and lung cancer can also cause pulmonary-induced dyspnea.

Pulmonary dyspnea is common in 1. Airway obstruction: such as inflammation of the larynx, trachea, bronchi, edema, stenosis or obstruction caused by tumors or foreign bodies, bronchial asthma, chronic obstructive pulmonary disease, etc.; 2. Lung diseases: such as pneumonia, lung abscess, tuberculosis, atelectasis, pulmonary congestion, pulmonary edema, diffuse pulmonary interstitial disease, bronchiolar alveolar carcinoma, etc.; 3. Diseases of the chest wall, thoracic cage and pleural cavity

Such as chest wall inflammation, severe thoracic deformity, pleural effusion, spontaneous pneumothorax, extensive pleural adhesions, tuberculosis, trauma, etc.; 4. Neuromuscular diseases: such as polio involving the cervical spinal cord, acute polyradiculoneuritis and myasthenia gravis involving respiratory muscles, and drugs causing paralysis of respiratory muscles; 5. Diaphragmatic dysfunction: such as diaphragmatic paralysis, large amount of ascites effusion, huge abdominal tumor, gastric distension and the end of pregnancy.

a.Can cause dysfunction of pulmonary ventilation and/or pulmonary ventilation.

b.This can lead to hypoxia and/or carbon dioxide retention.

c.It may be accompanied by abnormalities in Xiangluchai's respiratory rate and rhythm, and the depth of breathing is normal (correct answer) DThere may be a "three-recessed sign".

e.Clinically, it can be divided into three types.

a.Expiratory abrupt and cautious dyspnea.

b.Dyspnea on exertion.

c.Nocturnal dyspnea.

d.Orthopnea.

e.Acute pulmonary edema.

The answer is true: a
