Copd has become the third leading cause of death after cardiovascular and cerebrovascular diseases and malignant tumors, and the "gold standard" for the diagnosis of chronic lung diseases such as COPD is lung function examination, Academician Zhong Nanshan has repeatedly stressed and called on people to pay attention to lung function examination, and proposed that "we should pay attention to lung function measurement like blood pressure".
What is a lung function test
Lung function examination is to determine the lung ventilation function through the measurement of respiratory volume, flow rate, pressure and the analysis of respiratory gas components, so as to understand the function of the respiratory system organs and tissues. Pulmonary function examination is one of the important examination items in the diagnosis, severity evaluation and curative effect evaluation of respiratory diseases. It is a common examination for chronic cough, shortness of breath, chest tightness and bronchial allergy, and is the gold standard in the diagnosis of COPD and asthma.
Purpose of pulmonary function examination
1. Early detection of respiratory tract and pulmonary disease;
2. Identify the cause of dyspnea and determine the location of airway obstruction;
3. Assess the severity of lung disease;
4. Evaluate surgical tolerance and the possibility of postoperative complications.
Who needs to have their lung function checked
1. Long-term chronic recurrent cough, sputum, suspected chronic bronchitis, bronchial asthma, interstitial lung disease and other diseases.
2. There is dyspnea, and the cause is unknown, and it is necessary to identify the cause and determine the location of airway obstruction.
3. People with chronic obstructive pulmonary disease, asthma, bronchiectasis and other diseases.
4. For patients undergoing thoracic surgery or upper abdominal surgery, preoperative pulmonary function examination can determine the operation tolerance and the possibility of postoperative complications.
5. Chest tightness and shortness of breath after activities, especially those whose symptoms gradually worsen during activities.
6. Long-term smoking or passive smoking, and long-term exposure to polluting gases and dust in the working environment may lead to occupational lung disease in high-risk groups.
Characteristics of pulmonary function examination
1. It is of great significance for clinical diagnosis and treatment: it is of great value in disease diagnosis, severity rating, efficacy evaluation and disease outcome.
2. Non-invasive: Compared with bronchoscopy which is invasive, chest X-ray examination with radiation, pulmonary function examination is almost non-invasive.
3. Repeated testing is convenient: Repeated testing can be performed at different times of the day or over a period of time to understand the changes, development and prognosis of the disease.
4. Cheap price: Although the charging standards are different in different regions, they are basically included in medical insurance.
5. Suitable for the management of chronic respiratory diseases: Because the examination can be repeated, long-term tracking and follow-up can be carried out for the management of chronic respiratory diseases, such as asthma and COPD.
