What is the role of a nebulizer?

A nebulizer is a medical device specifically designed to deliver medication in mist form, which can be inhaled directly into the lungs. This method allows for the rapid absorption of medication, particularly for conditions such as asthma or chronic obstructive pulmonary disease (COPD), where patients need quick relief from bronchoconstriction or inflammation in the airways. The mist produced by the nebulizer helps the medication reach deep into the respiratory tract, which can be more effective than oral medications or some other forms of delivery.

Other options, although they relate to respiratory care, do not accurately represent the primary function of a nebulizer. Sleep apnea is typically managed with devices like CPAP machines, while oxygen therapy involves administering oxygen but does not specifically relate to the mechanism of a nebulizer. Supporting ventilation usually refers to mechanical support for patients who are unable to breathe adequately, which also does not align with the specific purpose of a nebulizer in delivering medication. Thus, the ability of a nebulizer to provide medication in mist form is what makes this answer accurate.
