Nebulized inhalation is the most commonly used treatment for respiratory infectious diseases and allergic diseases. Nebulized inhalation is firstly considered in terms of drugs mainly hormones, including budesonide suspension, followed by beta agonists, salbutamol suspension (nebulized solution), terbutaline suspension (nebulized solution), both of which if combined can play the purpose of anti-inflammatory, antispasmodic and asthma. Nebulized inhalation also requires the cooperation of the patient, waiting for the mist to enter the respiratory tract as soon as possible to settle in the lungs, and requires a simple breath-holding action to allow the inhaled drug to settle in the lung gas for the purpose of anti-inflammatory, antispasmodic and asthma. If a pediatric patient cannot cooperate, face mask nebulizer inhalation can be given to the lung tissue through the nasal oropharynx to achieve anti-inflammatory, antispasmodic, and asthma, and to relieve the symptoms of cough, sputum, and dyspnea.
