Airway mucus-ciliary clearance function assay

The respiratory mucus-ciliary clearance function is measured to check the respiratory system's defense function. Airway testing provides a new approach to clinical and basic research in many lung diseases, where radioactive aerosol inhalation scans are non-invasive, reliable, and reproducible. In the mucus-ciliary removal system, there is a relatively thin layer of liquid glue around the cilia and a viscous gel layer on the outer layer. The cilia oscillate at a frequency of subseconds, pushing the mucus to the sensitive part of the bronchus or the pharynx. Basic Information Specialist Category: Respiratory Examination Category: Other Inspections Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: The lungs are healthy and have no symptoms of any disease. Positive: Long-term cough, expectoration, and varying degrees of difficulty breathing, especially after activity or during the cold season. In the compensatory period of cardiopulmonary function, the patient may have no symptoms when he is quiet. Once he is slightly active, symptoms such as shortness of breath, shortness of breath, palpitations, pain in the precordial area, fatigue, and chest tightness may occur. Pneumothorax, pulmonary bullae, emphysema, asthma, lung abscess, tuberculosis and other lung diseases. Tips: Pay attention to normal eating habits before check, pay attention to personal hygiene. Normal value The lungs are healthy and have no symptoms of any disease. Clinical significance Abnormal results: long-term cough, sputum and varying degrees of difficulty breathing, especially after activity or during the cold season. In the compensatory period of cardiopulmonary function, the patient may have no symptoms when he is quiet. Once he is slightly active, symptoms such as shortness of breath, shortness of breath, palpitations, pain in the precordial area, fatigue, and chest tightness may occur. Pneumothorax, pulmonary bullae, emphysema, asthma, lung abscess, tuberculosis and other lung diseases. People who need to be examined: patients with suspected pulmonary heart disease, pneumothorax, pulmonary bullae, emphysema, asthma, lung abscess, tuberculosis and other lung diseases. Positive results may be diseases: pneumothorax, pulmonary heart disease, emphysema, lung abscess, pulmonary bullae, tuberculosis, coronavirus infection precautions Forbidden before examination: Pay attention to normal eating habits and pay attention to personal hygiene. Requirements for inspection: Actively cooperate with the doctor. Inspection process The mucus-ciliary clearance function of the respiratory tract is one of the three major defense functions of the respiratory system. In the mucus-ciliary removal system, there is a relatively thin layer of liquid glue around the cilia and a viscous gel layer on the outer layer. The cilia oscillate at a frequency of subseconds, pushing the mucus to the sensitive part of the bronchus or the pharynx. The bronchiole cilia is not only shorter than the trachea and tracheal cilia, but the sway is slower, so the cilia gradually increase from the bronchiole to the trachea, and the mucus clearance rate increases gradually. The measurement was divided into 1 mucus flow rate measurement 2 and the clearance rate of the inhalation aerosol was measured. Respiratory mucus-ciliary clearance function (MCC) Radioactive aerosol inhalation scanning is the most common method for determining airway MCC. Inhaled aerosols must have substances that are incapable of permeating the airway epithelium and can only be removed by mucus-cilia, such as polystyrene labeled with radionuclides, iron oxide, and the like. After inhaling the radionuclide-labeled aerosol, the lungs are counted and visualized immediately using a counter or a camera to quantify the aerosol deposited in the lungs, and the resulting dynamic count or imaging of radioactivity in the lungs reflects Airway mucus-ciliary system for the removal of inhaled aerosols.
