What should I do if my lung function is damaged

The lungs are an important respiratory organ in the human body, and the health of lung function directly affects the respiratory system. People often feel difficulty breathing, or even airway obstruction and poor tolerance. They should go to the hospital to check their lung function in time to determine whether they have poor lung function, so as to avoid serious diseases such as pneumonia and asthma, which will affect their health. So what other damages may there be to poor lung function?

project

Pulmonary function tests include ventilation function, gas exchange function, respiratory regulation function and pulmonary circulation function, etc. There are many examination items and measurement indicators. In the past, pulmonary function instruments were mainly based on mechanical and chemical methods for detection. The measurement was cumbersome, time-consuming and labor-intensive, and the detection error was large, which limited its widespread clinical application and medical workers had limited knowledge of it. In recent years, with the development of science and technology, the emergence of new detection technologies, especially the application of electronic computers, lung function testing technology has made great progress, and its importance in clinical practice has been increasingly recognized.

Purpose

Pulmonary function tests are mainly used for the following purposes:

1. Early detection of lung and respiratory tract lesions.

2. Identify the cause of dyspnea and determine the location of airway obstruction.

3. Assess the severity of lung disease.

4. Assess surgical tolerance and the possibility of postoperative complications.

5. Physical examination, assessment of labor intensity and tolerance;

6. Monitoring of critically ill patients, etc.

Features

1. Pulmonary function test is a physical examination method that does not cause any damage to the body and does not cause pain or discomfort.

2. Pulmonary function tests have the advantages of high sensitivity, convenient repeated testing and easy acceptance by patients.

3. Compared with chest X-ray, CT and other examinations, pulmonary function tests focus more on understanding the functional changes of the lungs and are an important means of examining respiratory diseases.

importance

1. Diagnose the patient's respiratory function status and determine the nature and extent of lung function damage.

2. Pulmonary function tests are required to diagnose COPD.

3. Pulmonary function tests help clinicians determine the severity of COPD and develop appropriate treatment plans based on the severity of the disease.

Object

1. People with recurrent upper respiratory tract infections: observe whether lung function is damaged

2. History of smoking and chronic cough - see if the small airway function has changed

3. Seasonal cough and asthma attacks - see if you have asthma

4. Regular review of chronic bronchitis - monitoring the course of the disease

5. Abnormal chest X-ray: Determine the degree of lung function damage

6. Risk assessment of anesthesia and surgery, and prediction of postoperative recovery

Asthma patients

During a typical asthma attack, pulmonary function tests first show obstructive lesions, but not all obstructive lesions are asthma. Further confirmation can be done by airway dilation test to confirm asthma. For patients with atypical asthma or asthma in remission or with negative airway dilation test, airway provocation test may be performed as appropriate to confirm asthma.

child

1. Repeated coughing or wheezing;

2. Cough lasts for more than 2 to 3 weeks and antibiotic treatment is ineffective;

3. Repeated "colds" develop into the lower respiratory tract and last for more than 10 days;

4. Assessment of the condition of children with asthma;

5. Acute onset of choking cough, hoarseness, and difficulty breathing;

6. Early differentiation of acute bronchitis, pneumonia and asthma in infants and young children;

7. Other respiratory diseases.

Performance

The manifestations of respiratory diseases in pulmonary function tests mainly include:

1. Obstructive lesions: refers to changes in airflow obstruction caused by narrowing of the respiratory tract due to various factors, among which asthma is the most obvious.

2. Restrictive lesions: refers to changes in which the respiratory movement of the lungs is restricted, resulting in a decrease in lung ventilation. Diseases such as emphysema, pleurisy, and hydropneumothorax all have varying degrees of decreased lung ventilation.

3. Mixed lesions: refers to both obstructive and restrictive lesions, such as chronic obstructive pulmonary disease, late-stage asthma, pneumoconiosis, and pediatric bronchopneumonia.

Detection

1. Because your nose is pinched, you should keep breathing through your mouth.

2. Hold your mouth as tightly as possible to ensure that there is no air leakage during the test.

3. Follow the operator's instructions as much as possible and exhale and inhale immediately

4. Inhale as much as possible, and then exhale with maximum force and speed.
