When used in a standardized manner, nebulization is not harmful to the lungs. Nebulization mainly refers to aerosol inhalation therapy, the use of high-speed oxygen airflow, so that the drug solution to form a mist, inhaled by the respiratory tract, to play a clean airway, humidification of the airway, antispasmodic, anti-inflammatory, expectorant and other local or systemic therapeutic purposes. Nebulization therapy has the following advantages: less dosage, precise drug delivery, and fast effect. 1. Less drug dosage: nebulized therapy is to disperse the drug into tiny droplets, directly into the respiratory tract, the dosage is small, which will reduce the toxic side effects of the drug. 2. Precise drug delivery: nebulization can deliver the drugs directly to the diseased parts of the respiratory tract and lungs, directly to the lesions, and deliver the drugs more accurately. 3. Fast-acting: Compared with oral medication, nebulized medication reaches the lesions directly and has a fast-acting effect. Although nebulization is not harmful to the lungs and has the advantages mentioned above, it is necessary to go to the hospital for nebulization treatment to ensure the safety and efficacy of the treatment.
