On November 20, 2024, the world will celebrate the 23rd World Chronic Obstructive Pulmonary Disease Day (COPD Day), with the theme "Know Your Lung Function".
What is Chronic Obstructive Pulmonary Disease?
Chronic obstructive pulmonary disease (COPD) is a common, preventable and treatable chronic respiratory disease, which is characterized by persistent respiratory symptoms and restriction of airflow in and out of lung tissues, and the main symptoms are chronic cough, sputum production, shortness of breath or dyspnea.
The situation of COPD in China is severe, and it has become the third largest "killer" of residents' health, second only to ischemic heart disease and stroke. According to the statistics of the joint research network, the number of COPD patients in China has increased from 103.5 million in 2018 to 106.4 million in 2022, and the number of COPD patients is expected to reach 109.1 million by 2027.

atomizer
Nebulized inhalation therapy is the most widely used method for the treatment of COPD in recent years. The drug can be output into very fine aerosol particles through a nebulizer inhalation device, which can enter the airways and lungs to exert its efficacy. The particle size of the nebulizer directly affects where the drug is deposited in the respiratory tract. For COPD patients, the particle size of 3-5 microns is more suitable for the treatment of the disease.
The median particle size of the nebulizer is 3.5 microns, and the atomization rate is as high as 0.2-0.4ml/min, which is conducive to drug diffusion and absorption.

Oximeter
Home oximeters can estimate and monitor blood oxygen saturation and can help identify invisible hypoxia. For patients with COPD, especially those with long-term supplemental oxygen therapy, oxygen saturation is an important observation indicator.
The Jianao oximeter uses advanced algorithms to measure accurately, and the readings are clear and convenient.

Ventilators
The lung function of COPD patients is almost exhausted, and the contraction and relaxation of the alveoli cannot be like normal people, just like the balloon has no elasticity, resulting in air inhalation and exhaust gas cannot be discharged, resulting in hypoxia accompanied by carbon dioxide retention.
In this case, a ventilator is used to squeeze air into the lungs and pump carbon dioxide out of the alveoli through the pressure of the airflow, while also squeezing out the sputum and improving carbon dioxide retention – which fundamentally alleviates the damage of COPD to the body. Long-term ventilator ventilation for many patients with COPD during the stable period can significantly improve quality of life and survival.
