How to distinguish the severity of COPD?

Chronic obstructive pulmonary disease (COPD) can be classified as mild, moderate, severe, and very severe COPD. Usually patients with mild COPD or no cough and phlegm, patients may not be aware of their abnormal lung function, moderate patients will have shortness of breath and shortness of breath increased significantly, severe COPD patients will react, seriously affecting the quality of life of patients, including severe COPD patients have significantly reduced quality of life, if there is an acute exacerbation may be life-threatening.

Chronic obstructive pulmonary disease (COPD) is a chronic obstructive pulmonary disease (COPD), which is characterized by incomplete reversible airflow limitation and is characterized by symptoms such as dyspnea and wheezing. Pulmonary function test is an objective index for judging airflow limitation and good reproducibility, which is of great significance for the diagnosis, severity evaluation, disease progression, prognosis and response of acute exacerbation of COPD. Chronic development of bronchitis is prone to form.

It is advisable to check explicitly**.

The key to COPD** is to prevent it, because each time** it will lead to worsening of symptoms, worsening lung function, and even death. It is recommended that patients pay attention to improving their own immunity, avoid, especially to prevent colds, and avoid bronchitis and other attacks. Eat more fresh vegetables and fruits, eat high-protein foods, suffer from COPD, according to the current symptoms are cough, wheezing, chest tightness, COPD patients should exercise appropriately in their daily life, eat a healthy diet, drink more water, **COPD disease TCM ** has the best effect, I hope that patients will recover their health as soon as possible.

Pulmonary bullae refer to the formation of an air-containing sac cavity in the lung tissue due to the increase in pressure in the alveolar cavity caused by various reasons, the rupture of the alveolar wall, and the fusion of each other. Pulmonary bullae are generally inflammatory lesions secondary to the small bronchi, and there are also some unclear idiopathic pulmonary bullae.

Hello, according to the national "Diagnostic Criteria for Chronic Obstructive Pulmonary Disease", COPD is divided into four grades: the first stage is mild (generally does not affect life and work), the second stage is moderate (the patient should rest**, can do light physical housework, and the disease response is strong), the third stage is severe (the patient has abnormal pain, inability to move, lack of appetite for food, accompanied by a certain degree of complications, such as low heart function (heart failure), and stage IV very severe (with significant complications and critical illness).

Diagnostic criteria for chronic obstructive pulmonary disease" can be found in the Ministry of Health and China.

Grade 1: mild COPD, FEV1 FVC % < 70% after inhalation of bronchodilators, FEV1 (1 second dose) greater than or equal to 80% (measured percentage of predicted value) with or without chronic symptoms (cough, sputum production);

Grade 2: moderate COPD, FEV1 FVC % < 70% after inhalation of bronchodilators, FEV1 (1 second dose) less than 80% (measured percentage of predicted value), greater than or equal to 50% (measured % of predicted value) with or without chronic symptoms (cough, sputum production, dyspnea);

Grade 3: severe COPD, FEV1 FVC% <70% after inhalation of bronchodilators, FEV1 (1 second volume) less than 50% (measured percentage of estimated value), greater than or equal to 30% (measured percentage of estimated value), with or without chronic symptoms (cough, sputum production, dyspnea);

Grade 4: Very severe COPD, FEV1 after inhalation of bronchodilators < 70% FVC%, FEV1 (1 second amount) less than 30% (measured percentage of the estimated value), accompanied by chronic symptoms (cough, sputum production, difficulty breathing) or respiratory failure.

Hello, chronic obstructive pulmonary emphysema, also known as COPD, refers to the expansion and overinflation of the distal air space at the end of the bronchi, and the elastic retraction of lung tissue is reduced.

All the elements that cause inflammatory changes in the bronchioles and the same group of plugs can lead to diffuse emphysema, the most common ** is chronic bronchitis, followed by bronchial asthma, bronchiectasis, smoking, air pollution infections, etc.

Smoking is one of the main causes of obstructive emphysema, so it is important for people with COPD to quit smoking.

COPD is the lungs of the body, chronic obstructive disease, the lungs will be damaged, the normal gas exchange of the human body will be affected, will cause the lungs and multiple organs to be in a state of hypoxia, the patient will show dyspnea, cough and sputum symptoms, will also cause weakness of the limbs and other symptoms, the disease may be caused by long-term inhalation of polluting gases, or harmful particles, you can take oral antibiotic drugs ** condition, when going out, it is best to wear a mask.

Chronic obstructive pulmonary disease (COPD) is short for chronic obstructive pulmonary disease. Chronic refers to the illness that persists and cannot be cured; Lung disease is when the disease occurs in the lungs; Obstructive refers to disorders characterized by incomplete reversible obstruction of the airways to varying degrees. Normal airways are responsible for transporting gas to the lungs, like the forks of a tree branch, and the airways become thinner and thinner.

Chronic obstructive pulmonary disease, also known as chronic obstructive pulmonary disease (COPD), is a condition characterized by incomplete reversible airflow limitation. Chronic obstructive pulmonary disease (COPD) is a devastating lung disease characterized by progressive irreversibility.

COPD is the abbreviation of chronic obstructive pulmonary disease in English, which is translated into Chinese"Chronic obstructive pulmonary disease"Most of the chronic bronchitis and emphysema we often talk about belong to COPD.

The main manifestations are cough, sputum production, heavy in the morning, the sputum is viscous and not easy to cough up, and the sputum is mostly white mucus foam.

After infection or exposure to cold, the condition worsens rapidly, with increased sputum volume, viscosity, or yellowish purulent sputum. As the disease progresses, the patient has a cough and sputum throughout the year. However, not all patients with cough and sputum will develop COPD.

COPD is emphysema, which is a difficult disease that needs to be treated with compound Chuanbei ginkgo soup.

The clinical manifestations of COPD are cough, sputum production, shortness of breath or dyspnea, chest tightness, and other symptoms. Long-term recurrent cough is a prominent manifestation of COPD, breakfast is heavier, cough at night is less significant, cough usually coughs up a small amount of gray-white mucus sputum after coughing, patients have shortness of breath and dyspnea are the hallmark symptoms of COPD, the early stage only appears after exertion, the later condition worsens, and even when resting also feel shortness of breath. Patients in the advanced stage will have weight loss, loss of appetite, mental depression and other manifestations.

The full name of COPD is chronic obstructive pulmonary disease, which is a disease with a relatively high disability rate and mortality rate, and is actually a problem of chronic bronchitis and emphysema. This disease not only causes respiratory impairment in patients, but also affects the function of the circulatory system, which can be life-threatening in severe cases. It is necessary to use comprehensive conditioning methods such as drugs, oxygen, psychology, diet, and exercise.

COPD is the lungs of the body, chronic obstructive disease, the lungs will be damaged, the normal gas exchange of the human body will be affected, will cause the lungs and multiple organs to be in a state of hypoxia, the patient will show dyspnea, cough and sputum symptoms, will also cause weakness of the limbs and other symptoms, the disease may be caused by long-term inhalation of polluting gases, or harmful particles, you can take oral antibiotic drugs ** condition, when going out, it is best to wear a mask.

COPD should be distinguished from bronchial asthma, bronchiectasis, congestive heart failure, tuberculosis, bronchial lung cancer, bronchiolitis obliterans, etc. Differentiating from bronchial asthma can sometimes be difficult. COPD is more likely to develop after middle age, while asthma is more likely to start in childhood or adolescence.

Symptoms of COPD progresse slowly and worsen gradually, while symptoms of asthma fluctuate widely. COPD mostly has a history of long-term smoking and/or exposure to harmful gases and toxic particles, while asthma is often accompanied by specific constitution, allergic rhinitis and/or eczema, and some patients have a family history of asthma. Chronic obstructive pulmonary pulmonary airflow limitation is basically irreversible, while asthma is mostly reversible.

However, in some patients with prolonged asthma, airflow limitation cannot be completely reversed if airway remodeling has occurred; In contrast, a small number of patients with COPD with airway hyperresponsiveness may have partially reversible airflow limitation. Differentiation should be based on a thorough analysis of clinical and laboratory tests, with bronchial provocation, bronchiectasis, and/or diurnal variability of maximal expiratory flow (PEF) as necessary. In a small percentage of patients, the two disorders may overlap.

Chronic obstructive pulmonary disease, also known as chronic obstructive pulmonary disease, is most likely due to chronic bronchitis or pneumoconiosis. Chronic obstruction of the respiratory tract caused by other reasons, caused by the occurrence of COPD. In this case, chronic obstructive pulmonary disease can be detected and diagnosed through clinical manifestations and chest CT examination, as well as lung ventilation volume, bronchial provocation test and other tests, and it is recommended to pay attention to rest, improve one's own immunity, inject flu vaccine during the flu season, and avoid colds.

In addition to the chest imaging findings, pulmonary function tests are most important. Pulmonary function tests can be used as a gold standard in diagnosing and evaluating COPD to objectively determine the degree of airflow obstruction.

With a FV1 FVC of less than 70% after bronchodilator application, the diagnosis of COPD with airflow obstruction that cannot be completely reversed can be confirmed.

The severity was further graded according to the ratio of the predicted values measured by FEV1.
