The nebulizer is a device specially used to treat upper respiratory diseases, such as cold, fever, cough, sputum, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumonia, and other diseases. The medicine enters the respiratory tract and lungs through breathing and inhalation and reaches the affected area directly. Therefore, nebulization treatment takes effect faster than oral medicine. And because the drug directly enters the respiratory tract, its dosage needs only one-tenth of the oral method, which significantly reduces the toxic and side effects of the drug, which is especially important for children and the elderly. Therefore, the atomization treatment is effective and safe.
