The value of aerosol inhalation therapy through inhalation, while increasing humidity and liquefying sputum, has been established in the treatment of patients with chronic airway obstruction. Inhalation therapy can improve bronchial clearance. However, severe airway obstruction and respiratory insufficiency inhaled aerosol bronchodilator capacity is often limited. These patients require the use of respirators to assist in atomization therapy
