Patients with bronchial asthma can undergo nebulization, especially pediatric asthma patients who are more suited for nebulizer therapy. Nebulization inhalation is currently a safe and effective method for treating childhood asthma and is listed by the World Health Organization as the first choice for global asthma prevention and treatment. For severe asthma during acute exacerbations and attack periods, nebulization therapy is not recommended. When using nebulization therapy, it is important to regularly disinfect the nebulizer and replace it periodically. During severe bronchospasm, it is important to avoid using excessive doses of receptor agonists, and care should be taken to avoid too low drug concentrations during nebulization, as it is not conducive to the effectiveness of the treatment.
