Introduction

Introduction The respiratory rate of a person with difficulty in breathing is 16-20 times/min in adults, and the ratio of the number of beats to the heart is 1:4. When the patient feels that the air is insufficient, the breathing is laborious, objectively, the patient has strong breathing, the respiratory muscles and the auxiliary respiratory muscles all participate in the respiratory movement, the ventilation increases, and the respiratory frequency, depth and rhythm change. Dyspnea is an important symptom of respiratory insufficiency. It is subjectively characterized by insufficient air or breathing, and objectively manifested as changes in respiratory rate, depth, and rhythm.

Cause

Cause

Stenosis, obstruction of the larynx, trachea, and large bronchi caused by various causes:

1 throat disease, such as acute laryngitis, laryngeal edema, throat, diphtheria, throat cancer.

2 tracheal diseases, such as bronchial tumors, tracheal foreign body or tracheal compression (gothal enlargement, lymphadenopathy or aortic aneurysm compression). The main manifestation is that the inspiratory exercise is strengthened, the inhalation is deep and laborious, and the heavy ones lean back when inhaling.

Pulmonary diffusion function measurement (DL)

The main manifestation is that the inspiratory exercise is strengthened, the inhalation is deep and laborious, and the heavy ones lean back when inhaling.

1. Blood routine examination: When the infection is increased, the white blood cell count is increased, the neutrophils are increased, and the eosinophil count is increased in the allergic disease.

2. Device examination: X-ray examination has obvious cardiopulmonary X-ray signs of dyspnea caused by heart and lung disease.

3. Bronchial angiography: bronchiectasis, bronchial adenoma and cancer.

4. Patients with heart disease can do electrocardiogram, echocardiography and other tests.

5. Perform lung function tests on chronic lung diseases such as chronic obstructive pulmonary disease (COPD) and bronchial asthma, and diagnose the nature and extent of lung function damage.
