The effects and benefits of nebulization include treating coughs, thinning phlegm, and improving airway spasms. Side effects include the possibility of bacterial contamination of the nebulizer, plus the possibility of nausea, vomiting, and other discomforts while nebulizing. Nebulization generally uses high-speed airflow to disperse the medication into small suspended droplets that float in the air and are inhaled into the airway through respiration, so that the medication is fully dispersed across the bronchial mucosa to achieve the effect of treating the disease. Clinically used to treat bronchial asthma, bronchial infections, chronic obstructive pulmonary disease. For example, for coughing and sputum dilution, inhalation budesonide suspension, inhalation acetylcysteine solution and other medications are commonly used for nebulization treatment. To reduce local bronchial mucosal congestion, edema, dilute sputum and so on. In order to improve airway resistance, bronchodilators such as salbutamol inhalation aerosol and ipratropium bromide solution for inhalation are commonly used to relieve bronchospasm and reduce airway hyperresponsiveness. However, care should be taken that the nebulizer is not cleaned and bacteria multiply, which may exacerbate lung infections during nebulization. Nebulizer irritation of the throat may cause nausea, vomiting, and even worsening of cough during nebulization. It is recommended to use nebulization treatment under the guidance of a doctor to avoid adverse reactions.
