Used in respiratory therapy to administer medication directly to the lungs through inhalation. It is commonly used to treat conditions such as asthma, chronic obstructive pulmonary disease (COPD), bronchitis, and other respiratory disorders.

It is connected to a nebulizer machine, which converts liquid medication into a fine mist or aerosol which is inhaled by the patient through the mask, allowing the medication to reach the respiratory tract and provide targeted relief.
